LDPC stabilizer codes as gapped quantum phases: stability under graph-local perturbations
Wojciech De Roeck, Vedika Khemani, Yaodong Li +2
We generalize the proof of stability of topological order, due to Bravyi, Hastings and Michalakis, to stabilizer Hamiltonians corresponding to low-density parity check (LDPC) codes…
Classification of symmetry protected states of quantum spin chains for continuous symmetry groups
Bruno de Oliveira Carvalho, Wojciech De Roeck, Tijl Jappens
Symmetry protected states (SPT's) of quantum spin systems were studied by several authors. For one-dimensional systems (spin chains), there is an essentially complete and rigorous…
Producing suprathermal tails in the stationary velocity distribution
Thibaut Demaerel, Wojciech De Roeck, Christian Maes
We revisit effective scenarios for the origin of heavy tails in stationary velocity distributions. A first analysis combines localization with diffusive acceleration. That gets rea…
A many-body index for quantum charge transport
Sven Bachmann, Alex Bols, Wojciech De Roeck +1
We propose an index for pairs of a unitary map and a clustering state on many-body quantum systems. We require the map to conserve an integer-valued charge and to leave the state,…
How a small quantum bath can thermalize long localized chains
David J. Luitz, François Huveneers, Wojciech de Roeck
We investigate the stability of the many-body localized (MBL) phase for a system in contact with a single ergodic grain, modelling a Griffiths region with low disorder. Our numeric…
Reduced and Extended Weak Coupling Limit
J. Derezinski, W. De Roeck
We give an extended review of recent work on the extended weak coupling limit. Background material on completely positive semigroups and their unitary dilations is given, as well a…
