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 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…

SPT indices emerging from translation invariance in two dimensional quantum spin systems
Tijl Jappens
We consider SPT-phases with on-site (where is any finite group) symmetry for two-dimensional quantum spin systems. We then impose translation invariance in one direction an…
