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…
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,…
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…
