Interactions enable Thouless pumping in a nonsliding lattice
Konrad Viebahn, Anne-Sophie Walter, Eric Bertok +5
A topological 'Thouless' pump represents the quantised motion of particles in response to a slow, cyclic modulation of external control parameters. The Thouless pump, like the quan…

Splitting of topological charge pumping in an interacting two-component fermionic Rice-Mele Hubbard model
E. Bertok, F. Heidrich-Meisner, A. A. Aligia
A Thouless pump transports an integer amount of charge when pumping adiabatically around a singularity. We study the splitting of such a critical point into two separate critical p…
