Floquet Gauge Pumps as Sensors for Spectral Degeneracies Protected by Symmetry or Topology
Abhishek Kumar, Gerardo Ortiz, Philip Richerme +1
We introduce the concept of a Floquet gauge pump whereby a dynamically engineered Floquet Hamiltonian is employed to reveal the inherent degeneracy of the ground state in interacti…

String order via Floquet interactions in atomic systems
Tony E. Lee, Yogesh N. Joglekar, Philip Richerme
We study the transverse-field Ising model with interactions that are modulated in time. In a rotating frame, the system is described by a time-independent Hamiltonian with many-bod…
