SUMMARY:Higher Berry Phases\, Tensor Networks\, and Boundary Conformal Fie
 ld Theory - Shinsei Ryu (Princeton University)

DESCRIPTION:The higher Berry phase is a generalization of the Berry phase 
 in quantum mechanics to extended quantum systems\, such as quantum many-bo
 dy systems on spatial lattices and quantum field theories. In this talk\, 
 I will describe how higher Berry phases can be defined and calculated for 
 short-range entangled (invertible) quantum many-body systems using tensor 
 networks\, such as matrix product states and projected entangled pair stat
 es. I will also present a complementary formulation within the framework o
 f quantum field theory\, focusing in particular on boundary conformal fiel
 d theory in 1+1 dimensions.
