The University of Kent has an active research community studying a range of phenomena in theoretical and applied condensed matter physics. The School of Physical Sciences hosts the interdisciplinary Functional Materials Group, with major recent investments in both theory and experiment of correlated quantum matter.
Of particular interest to the quantiki community, several theory groups within the Quantum Materials and Magnetism are working with quantum information methods, including DMRG (groups of Sam Carr and Gunnar Möller), tensor networks (Gunnar Möller) and other entanglement based approaches (group of Jorge Quintanilla). Some overarching themes of our research are: relativistic quantum-mechanical effects (e.g. spin-orbit coupling) in rare earths and superconductors; topological aspects of condensed matter physics; light-matter interactions; ferroic complex oxides and their interfaces; and new quantum phases of matter.
Closely related experimental work is undertaken in the groups of Silvia Ramos (neutron scattering), and Emma Pugh (low temperature, high pressure, high field experiments).
Applications from Indian nationals are invited for the position of a Research Associate (initially for 1 year, extendable upto 3 years based on performance) under the project “Topology, quantum computation and spintronics with Dirac materials” in the School of Physical Sciences, NISER funded by DST Nanomisssion, Govt. of India.
Qualification - Candidate should have Ph.D degree in Physics (or, should have submitted the thesis), preferably in theory. Fellowship: Rs.24,000+HRA (as per DST norms) per month. Age: Maximum 35 years.
The SQC group is active in the field of Quantum computing with superconducting devices, in particular phase and flux qubits based on SQUIDs, and in fields related to these topics.
The IFN is an institute of the Italian CNR devoted to the study and fabrication of advanced devices for photonics, optoelectronics and electronics. Nanotechnologies play a prominent role in these research fields. The combined expertise in nanofabrication, materials and photonics creates a synergy able to compete in this very new and challenging field.
