Generalized Thouless Pumps in 1+1-dimensional Interacting Fermionic Systems

Shuhei Ohyama, Ken Shiozaki, Masatoshi Sato

The Thouless pump is a phenomenon in which $\mathrm{U}(1)$ charges are pumped from an edge of a fermionic system to another edge. The Thouless pump has been generalized in various…
