Higher structures in matrix product states
Shuhei Ohyama, Shinsei Ryu
For a parameterized family of invertible states (short-range-entangled states) in dimensions, we discuss a generalization of the Berry phase. Using translationally-invarian…

Discrete Higher Berry Phases and Matrix Product States
Shuhei Ohyama, Yuji Terashima, Ken Shiozaki
A -parameter family of invertible states gives a topological transport phenomenon, similar to the Thouless pumping. As a natural generalization of this, we can consider a family…
