Research project Frontiers of topological matter
This project focuses on frontiers of topological matter such as non-Abelian anyons from twists and defects in Moiré heterostructures and topological phenomena in open dissipative systems.
In particular we will consider two complementary frontiers:
(i) Non-Abelian anyons from twists and defects in Moiré heterostructures, including (a) the search for new hosts of non-Abelian fractional Chern insulators and (b) microscopic models of dislocations, primarily in twisted graphene-based multilayer systems, with the goal of identifying ideal premises for a class of non-Abelian anyons known as genons.
(ii) Dissipative topological matter (a) extending our recent work on non-Hermitian topology to the quantum many-body realm and (b) exploring possible applications of non-Hermitian topological sensing.
Albeit being distinct in detail, the parallel theoretical studies of these setups are expected to bring synergy, especially conceptually, by enabling cross-fertilisation between the topics, but also regarding the development of numerical and techniques. Recurring themes include proximity and commensurability effects and non-equilibrium responses to external probes.
