Floquet Engineering of Hilbert Space Fragmentation in Stark Lattices
Li Zhang, Yongguan Ke, Ling Lin +1
The concept of Hilbert space fragmentation (HSF) has recently been put forward as a routine to break quantum ergodicity. Although HSF exists widely in models with dynamical constra…

Calculations of Chern number: equivalence of real-space and twisted-boundary-condition formulae
Ling Lin, Yongguan Ke, Li Zhang +1
Chern number is a crucial invariant for characterizing topological feature of two-dimensional quantum systems. Real-space Chern number allows us to extract topological properties o…
