Classification of unitary operators by local generatability
Xu Liu, Adrian B. Culver, Fenner Harper +1
Periodically driven (Floquet) systems can exhibit possibilities beyond what can be obtained in equilibrium. Both in Floquet systems and in the related problems of discrete-time qua…

Emergent fermionic gauge theory and foliated fracton order in the Chamon model
Wilbur Shirley, Xu Liu, Arpit Dua
The Chamon model is an exactly solvable spin Hamiltonian exhibiting nontrivial fracton order. In this work, we dissect two distinct aspects of the model. First, we show that it exh…

Chiral Flow in One-dimensional Floquet Topological Insulators
Xu Liu, Fenner Harper, Rahul Roy
We propose a bulk topological invariant for one-dimensional Floquet systems with chiral symmetry which quantifies the particle transport on each sublattice during the evolution. Th…
