Higher Berry curvature from matrix product states
Ken Shiozaki, Niclas Heinsdorf, Shuhei Ohyama
The higher Berry curvature was introduced by Kapustin and Spodyneiko as an extension of the Berry curvature in quantum mechanical systems with finite degrees of freedom to quantum…

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…
