Abstract:
We study a kinetically constrained pair-hopping model that arises within a Landau level in the quantum Hall effect. At filling ν=1/3, the model exactly maps onto the so-called “PXP model,” a constrained model for the Rydberg atom chain that is numerically known to exhibit ETH-violating states in the middle of the spectrum or quantum many-body scars. Indeed, particular charge density wave configurations exhibit the same revivals seen in the PXP model. We generalize the mapping to fillings factors...     »
