How periodic driving stabilises and destabilises Anderson localisation on random trees
Sthitadhi Roy, Roderich Moessner, Achilleas Lazarides
Motivated by the link between Anderson localisation on high-dimensional graphs and many-body localisation, we study the effect of periodic driving on Anderson localisation on rando…
Self-consistent theory of mobility edges in quasiperiodic chains
Alexander Duthie, Sthitadhi Roy, David E. Logan
We introduce a self-consistent theory of mobility edges in nearest-neighbour tight-binding chains with quasiperiodic potentials. Demarcating boundaries between localised and extend…
Measurement and entanglement phase transitions in all-to-all quantum circuits, on quantum trees, and in Landau-Ginsburg theory
Adam Nahum, Sthitadhi Roy, Brian Skinner +1
A quantum many-body system whose dynamics includes local measurements at a nonzero rate can be in distinct dynamical phases, with differing entanglement properties. We introduce th…
Localisation on certain graphs with strongly correlated disorder
Sthitadhi Roy, David E. Logan
Many-body localisation in interacting quantum systems can be cast as a disordered hopping problem on the underlying Fock-space graph. A crucial feature of the effective Fock-space…
