Lattice model constructions for gapless domain walls between topological phases

HIGHLIGHTS

• who: Chenfeng Bao from the Perimeter Institute for Theoretical Physics, Waterloo, Ontario N L, Canada Tsinghua University have published the Article: Lattice model constructions for gapless domain walls between topological phases, in the Journal: (JOURNAL) of 14/04/2022
• what: The low-energy Hilbert space of the model is again made up of closed string states. This model has a Z2 symmetry iu03c0 z z x z u03c4u0304 u03c4u0304 Sdw=u03c4u0304n exp - u03c4u0304n - 1, 4 n n+1 n n which the authors will show in Sec III is indeed the Z2 symmetry inherited from . . .
