Two hundred and nine senior scientists from across Europe were awarded grants in today’s announcement, representing a total of €507 million in research funding. ̽��ֱ��UK has 51 grantees in this year’s funding round, the most of any ERC participating country.

ERC grants are awarded through open competition to projects headed by starting and established researchers, irrespective of their origins, who are working or moving to work in Europe. ̽��ֱ��sole criterion for selection is scientific excellence. ERC Advanced Grants are designed to support excellent scientists in any field with a recognised track record of research achievements in the last ten years. Apart from strengthening Europe’s knowledge base, the new research projects will also lead to the creation of some 1,900 new jobs for post-doctoral fellows, PhD students and other research staff.

Professor Melinda Duer from the Yusuf Hamied Department of Chemistry has been awarded a grant for her EXTREME project to explore the chemistry that happens when a biological tissue stretches or breaks.

So-called mechanochemistry leads to molecules being generated within the tissue that may be involved in communicating tissue damage to cells. Detecting and understanding this chemistry is highly relevant for understanding ageing, and for developing new therapeutics for degenerative diseases and cancer.

“This award means I can do the research I’ve been dreaming about for the last ten years,” said Duer. “I am extremely grateful to the European Research Council for giving me this amazing opportunity. ̽��ֱ��ERC is one of the few organisations that understands the need for longer-term funding for high-risk, high-reward research, which is essential for this project. I really couldn’t be more delighted and I can’t wait to get started!”

Professor Manish Chhowalla, from the Department of Materials Science and Metallurgy, received funding for his 2D-LOTTO project, for the development of energy-efficient electronics.

“This grant will enable our research group to realise the next generation of energy-efficient electronics based on two-dimensional semiconductors,” he said. “ ̽��ֱ��funding will also support a team of students, early career researchers and senior academics to address the challenges of demonstrating practical tunnel field effect transistors.”

Professor Henning Sirringhaus from the Cavendish Laboratory received funding for his NANO-DECTET project, for the development of next-generation energy materials. “Worldwide, only about a third of primary energy is converted into useful energy services: the other two thirds are wasted as heat in the various industrial, transportation, residential energy conversion and electricity generation processes,” said Sirringhaus. “Given the urgent need to mitigate the dangerous consequences of climate change, a waste of energy on this scale needs to be addressed immediately.

“Thermoelectric waste-heat-to-electricity conversion could offer a potential solution, but the performance of thermoelectric materials is currently insufficient. In this project we will use the unique physics of molecular organic semiconductors, as well as hybrid organic-inorganic semiconductors, to make efficient, low-temperature thermoelectric materials.”

Professor Marcos Martinon-Torres from the Department of Archaeology received funding for his REVERSEACTION project, which will study how societies in the past cooperated. “Many prehistoric societies did pretty well at maintaining rich and complex lives without the need for permanent power hierarchies and coercive authorities,” he said. “Arguably, they chose to cooperate, and not just to ensure survival. ̽��ֱ��lack of state structures did not stop them from developing and sustaining complex technologies, making extraordinary artefacts that required exotic materials, challenging skills and labour arrangements. I’m keen to understand why, but also how they managed.

“This grant couldn’t have come at a better time, as collective action is increasingly recognised as the only way to tackle some of our greatest global concerns, and there is value in studying how people collaborated in the past. With our labs freshly revamped through our recent AHRC infrastructure grant, we are ready to take on a new large-scale, challenging archaeological science project.”

Professor Marta Mirazon Lahr, also from the Department of Archaeology, was awarded funding for her NGIPALAJEM project, which will bring a new understanding of how the evolution of our species is part of a broader and longer African evolutionary landscape.

“My research is in human evolution, a field that advances through technical breakthroughs, new ideas, and critically, new fossils,” said Lahr. “A big part of my work is to find new hominin fossils in Africa, which requires not only supportive local communities and institutions, but long-term planning and implementation, a dedicated team, significant funds and the time to excavate, study, compare and interpret new discoveries. This new grant from the ERC gives me all this and more – and I just can’t wait to get started!”

Professor Richard Samworth’s RobustStats project will develop robust statistical methodology and theory for large-scale data. “Large-scale data are usually messy: they may be collected under different conditions, and data may be missing or corrupted, which makes it difficult to draw reliable conclusions,” said Samworth, from the Department of Pure Mathematics and Mathematical Statistics. “This grant will allow me to focus my time on developing robust statistical methodology and theory to address these challenges. Equally importantly, I will be able to build a group of PhD students and post-docs that will dramatically increase the scale and scope of what we are able to achieve.

Professor Zoran Hadzibabic from the Cavendish Laboratory was awarded funding for his UNIFLAT project. One of the great successes of the last-century physics was recognising that complex and seemingly disparate systems are fundamentally alike. This allowed the classification of the equilibrium states of matter into classes based on their basic properties. At the heart of this classification is the universal collective behaviour, insensitive to the microscopic details, displayed by systems close to phase transitions.

A grand challenge for modern physics is to achieve such a feat for the far richer world of the nonequilibrium collective phenomena. “Our ambition is to make a leading contribution to this worldwide effort, through a series of coordinated experiments on homogeneous atomic gases in two-dimensional (2D) geometry,” said Hadzibabic. “Specifically, we will study in parallel three problems – the dynamics of the topological Berezinskii-Kosterlitz-Thouless phase transition, turbulence in driven systems, and the universal spatiotemporal scaling behaviour in isolated quantum systems far from equilibrium. Each of these topics is fascinating and of fundamental importance in its own right, but beyond that we will experimentally establish an emerging picture that connects them.”

Dr Helen Williams from the Department of Earth Sciences said: “By funding the EarthMelt project, the ERC has given me the amazing opportunity to study the early evolution of the Earth and its transition from a largely molten state to the habitable planet we know today. This funding will also help me to develop exciting new instrumentation and analytical techniques, and, most importantly, mentor and support the next generation of PhD students and postdoctoral researchers working in geochemistry.”

Professor Sir Richard Friend from the Cavendish Laboratory has been awarded funding for his Spin Control in Radical Semiconductors (SCORS) project, which will explore the electronic properties of organic semiconductors that have an unpaired electron to give net magnetic spin. ̽��ֱ��project is based on a recent discovery that this unpaired electron can couple strongly to light, allowing very efficient luminescence in LEDs. Friend’s group will explore new combinations of optical excited states with magnetic spin states. This will allow new designs for LEDs and solar cells, and opportunities to control the ground state spin polarisation in spintronic devices.

Professor Christopher Hunter’s InfoMols project is focused on synthetic information molecules. “ ̽��ֱ��aim of our project is replication and evolution with artificial polymers,” said Hunter, from the Yusuf Hamied Department of Chemistry. “ ̽��ֱ��timeframe for achieving such a breakthrough is unpredictable, and it is the flexibility provided by an ERC award that makes tackling such challenging targets possible.”

Professor Mark Gross from the Department of Pure Mathematics and Mathematical Statistics received funding for his Mirror symmetry in Algebraic Geometry (MSAG) project, and Professor Geoffrey Khan from the Faculty of Asian and Middle Eastern Studies was awarded funding for ALHOME: Echoes of Vanishing Voices in the Mountains: A Linguistic History of Minorities in the Near East.

Twelve ̽��ֱ�� of Cambridge researchers have won advanced grants from the European Research Council (ERC), Europe’s premier research funding body. Their work is set to provide new insights into many subjects, such as how to deal with vast scales of data in a statistically robust way, the development of energy-efficient materials for a zero-carbon world, and the development of new treatments for degenerative disease and cancer. Cambridge has the most grant winners of any UK institution, and the second-most winners overall.

Quantum projects launched to solve universe’s mysteries

sc604 — Wed, 13 Jan 2021 09:00:00 +0000

UK Research and Innovation (UKRI) is supporting seven projects with a £31 million investment to demonstrate how quantum technologies could solve some of the greatest mysteries in fundamental physics. Researchers from the ̽��ֱ�� of Cambridge have been awarded funding on four of the seven projects.

Just as quantum computing promises to revolutionise traditional computing, technologies such as quantum sensors have the potential to radically change our approach to understanding our universe.

̽��ֱ��projects are supported through the Quantum Technologies for Fundamental Physics programme, delivered by the Science and Technology Facilities Council (STFC) and the Engineering and Physical Sciences Research Council (EPSRC) as part of UKRI’s Strategic Priorities Fund. ̽��ֱ��programme is part of the National Quantum Technologies Programme.

AION: A UK Atom Interferometer Observatory and Network has been awarded £7.2 million in funding and will be led by Imperial College London. ̽��ֱ��project will develop and use technology based on quantum interference between atoms to detect ultra-light dark matter and sources of gravitational waves, such as collisions between massive black holes far away in the universe and violent processes in the very early universe. ̽��ֱ��team will design a 10m atom interferometer, preparing the construction of the instrument in Oxford and paving the way for larger-scale future experiments to be located in the UK. Members of the AION consortium will also contribute to MAGIS, a partner experiment in the US.

̽��ֱ��Cambridge team on AION is led by Professor Valerie Gibson and Dr Ulrich Schneider from the Cavendish Laboratory, alongside researchers from the Kavli Institute for Cosmology, the Institute of Astronomy and the Department of Applied Mathematics and Theoretical Physics. Dr Tiffany Harte will co-lead the development of the cold atom transport and final cooling sequences for AION, and Dr Jeremy Mitchell will co-lead the data readout and network capabilities for AION and MAGIS, and undertake data analysis and theoretical interpretation.

“This announcement from STFC to fund the AION project, which alongside some seed funding from the Kavli Foundation, will allow us to target key open questions in fundamental physics and bring new interdisciplinary research to the ̽��ֱ�� for the foreseeable future,” said Gibson.

“Every physical effect, known or unknown, leaves its fingerprint on the phase evolution of a coherent quantum system such as cold atoms; it only requires sufficiently sensitive detectors,” said Schneider. “We are excited to contribute our cold-atom technology to this interdisciplinary endeavour and to develop atom interferometry into a powerful detector for fundamental physics.”

̽��ֱ��Quantum Sensors for the Hidden Sector (QSHS) project, led by the ̽��ֱ�� of Sheffield, has been awarded £4.8 million in funding. ̽��ֱ��project aims to contribute to the search for axions, low-mass ‘hidden’ particles that are candidates to solve the mystery of dark matter. They will develop new quantum measurement technology for inclusion in the US ADMX experiment, which can then be used to search for axions in parts of our galaxy’s dark matter halo that have never been explored before.

“ ̽��ֱ��team will develop new electronic technology to a high level of sophistication and deploy it to search for the lowest-mass particles detected to date,” said Professor Stafford Withington from the Cavendish Laboratory, Co-Investigator and Senior Project Scientist on QSHS. “These particles are predicted to exist theoretically, but have not yet been discovered experimentally. Our ability to probe the particulate nature of the physical world with sensitivities that push at the limits imposed by quantum uncertainty will open up a new frontier in physics.

“This new window will allow physicists to explore the nature of physical reality at the most fundamental level, and it is extremely exciting that the UK will be playing a major international role in this new generation of science.”

Professor Withington is also involved in the Determination of Absolute Neutrino Mass using Quantum Technologies, which will be led by UCL. ̽��ֱ��project aims to harness recent breakthroughs in quantum technologies to solve one of the most important outstanding challenges in particle physics – determining the absolute mass of neutrinos. One of the universe’s most abundant particles neutrinos are a by-product of nuclear fusion within stars, therefore being key to our understanding of the processes within stars and the makeup of the universe. Moreover, knowing the value of the neutrino mass is critical to our understanding of the origin of matter and evolution of the universe. They are poorly understood however, and the researchers aim to develop pioneering new spectroscopy technology capable to precisely measure the mass of this elusive but important particle.

Professor Zoran Hadzibabic has received funding as part of the Quantum Simulators for Fundamental Physics project, led by the ̽��ֱ�� of Nottingham. ̽��ֱ��project aims to develop quantum simulators capable of providing insights into the physics of the very early universe and black holes. ̽��ֱ��goals include simulating aspects of quantum black holes and testing theories of the quantum vacuum that underpin ideas on the origin of the universe.

Researchers will use cutting-edge quantum technologies to transform our understanding of the universe and answer key questions such as the nature of dark matter and black holes.
