A classification of -charge Thouless pumps in 1D invertible states
Sven Bachmann, Wojciech De Roeck, Martin Fraas +1
Recently, a theory has been proposed that classifies cyclic processes of symmetry protected topological (SPT) quantum states. For the case of spin chains, i.e.\ one-dimensional bos…

Derivation of Kubo's formula for disordered systems at zero temperature
Wojciech De Roeck, Alexander Elgart, Martin Fraas
This work justifies the linear response formula for the Hall conductance of a two-dimensional disordered system. The proof rests on controlling the dynamics associated with a rando…
