Percolation in Fock space as a proxy for many-body localisation
Sthitadhi Roy, J. T. Chalker, David E. Logan
We study classical percolation models in Fock space as proxies for the quantum many-body localisation (MBL) transition. Percolation rules are defined for two models of disordered q…
Exact solution of a percolation analogue for the many-body localisation transition
Sthitadhi Roy, David E. Logan, J. T. Chalker
We construct and solve a classical percolation model with a phase transition that we argue acts as a proxy for the quantum many-body localisation transition. The classical model is…
Landau levels, Bardeen polynomials and Fermi arcs in Weyl semimetals: the who's who of the chiral anomaly
Jan Behrends, Sthitadhi Roy, Michael H. Kolodrubetz +2
Condensed matter systems realizing Weyl fermions exhibit striking phenomenology derived from their topologically protected surface states as well as chiral anomalies induced by ele…
Nonequilibrium quantum order at infinite temperature: spatiotemporal correlations and their generating functions
Sthitadhi Roy, Achilleas Lazarides
Localisation-protected quantum order extends the idea of symmetry breaking and order in ground states to individual eigenstates at arbitrary energy. Examples include many-body loca…
Anomalous thermalization and transport in disordered interacting Floquet systems
Sthitadhi Roy, Yevgeny Bar Lev, David J. Luitz
Local observables in generic periodically driven closed quantum systems are known to relax to values described by periodic infinite temperature ensembles. At the same time, ergodic…
