Absolutely Stable Spatiotemporal Order in Noisy Quantum Systems
Max McGinley, Sthitadhi Roy, S. A. Parameswaran
We introduce a model of non-unitary quantum dynamics that exhibits infinitely long-lived discrete spatiotemporal order robust against any unitary or dissipative perturbation. Ergod…
Local resonances and parametric level dynamics in the many-body localised phase
S. J. Garratt, Sthitadhi Roy, J. T. Chalker
By varying the disorder realisation in the many-body localised (MBL) phase, we investigate the influence of resonances on spectral properties. The standard theory of the MBL phase…
Fock-space anatomy of eigenstates across the many-body localisation transition
Sthitadhi Roy, David E. Logan
We explore the Fock-space structure of eigenstates across the many-body localisation (MBL) transition in a disordered, interacting quantum spin-1/2 chain. Eigenstate expectation va…
Localisation in quasiperiodic chains: a theory based on convergence of local propagators
Alexander Duthie, Sthitadhi Roy, David E. Logan
Quasiperiodic systems serve as fertile ground for studying localisation, due to their propensity already in one dimension to exhibit rich phase diagrams with mobility edges. The de…
