Query: Quantum Many-body Scars in a Landau Level on a Thin Torus   We study a kinetically constrained pair hopping model that arises within a
Landau level in the quantum Hall effect. At filling $\nu = 1/3$, 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 $\nu = p/(2p+1)$, and show
that the model is equivalent to non-integrable spin-chains within particular
constrained Krylov Hilbert spaces. These lead to new examples of quantum
many-body scars which manifest as revivals and slow thermalization of
particular charge density wave states. Finally, we investigate the stability of
the quantum scars under certain Hamiltonian perturbations motivated by the
fractional quantum Hall physics.
