Zhao H, Vovrosh J, Mintert F, et al., Quantum Many-Body Scars in Optical Lattices
The concept of quantum many-body scars has recently been put forward as aroute to describe weak ergodicity breaking and violation of the EigenstateThermalization Hypothesis. We propose a simple setup to generate quantummany-body scars in a doubly modulated Bose-Hubbard system which can be readilyimplemented in cold atomic gases. The dynamics are shown to be governed bykinetic constraints which appear via density assisted tunneling in ahigh-frequency expansion. We find the optimal driving parameters for thekinetically constrained hopping which leads to small isolated subspaces ofscared eigenstates. The experimental signatures and the transition to fullythermalizing behavior as a function of driving frequency are analyzed.
