Quantum transport, Majorana fermions and other exotic excitations in condensed matter systems
Tuesday, 18th June 2019
Department of Physics, University of Warwick
Organisers: A. Chakrabarti (Presidency University, Kolkata), R.A. Römer (Warwick), S. Das (IISER Kolkata), N. Wilson (Warwick)
Background and Purpose
Transport of quasi-particle excitations in the quantum coherent regime is full of surprises even in the simplest models of non-interacting systems. The lattice structure, interplay of spin and orbital degrees of freedom, its composition and deviation, if any, from perfect periodicity, determines whether the material is an insulator or a metal, or a semi-metal, a Weyl metal or a Dirac metal. This is of course foremost due to the quantum, and hence wave-like, nature of such excitations. When long range entanglement induced by many-body interactions are taken into account, similar surprises in the form of exotic collective excitations can arise, given birth to phenomena such as exotic superconductivity and magnetism hosting excitation with fractional quantum numbers (like fraction charges) and fraction/non-abelian statistics (like Majorana fermions). In this workshop, we want to bring together some of the practitioners of various fields of quantum transport, ranging from the non-interacting approaches in non-standard environments to the Majorana and many-body approaches. The aim of the workshop is to understand each other’s approaches and strategies, be these analytical, numerical or experimental.
