Motivated by recent observations of ergodicity breaking due to Hilbert space fragmentation in 1D Fermi-Hubbard chains with a tilted potential [Scherg et al., arXiv:2010.12965], we show that the same system also hosts quantum many-body scars in a regime U≈Δ≫J at electronic filling factor ν=1. We numerically demonstrate that the scarring phenomenology in this model is similar to other known realizations such as Rydberg atom chains, including persistent dynamical revivals and ergodicity-breaking…

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
Weak ergodicity breaking from quantum many-body scars
The thermodynamic description of many-particle systems rests on the assumption of ergodicity, the ability of a system to explore all allowed configurations in the phase space. Recent studies on
Topological quantum many-body scars in quantum dimer models on the kagome lattice
It is demonstrated that bulk energies surrounding the scar are distributed according to the Gaussian ensemble expected of their respective symmetry sector, and contrast entanglement properties of the scar state with that of all other eigenstates.
Observing non-ergodicity due to kinetic constraints in tilted Fermi-Hubbard chains
Using analytical calculations, this work experimentally studies the relaxation of an initial charge-density wave and finds a remarkably long-lived initial-state memory over a wide range of parameters, which can be attributed to emergent kinetic constraints.

Emergent SU(2) Dynamics and Perfect Quantum Many-Body Scars.
A weak quasilocal deformation of the Rydberg-blockaded Hamiltonian is constructed, which makes the revivals virtually perfect and suggests the existence of an underlying nonintegrable Hamiltonian which supports an emergent SU(2)-spin dynamics within a small subspace of the many-body Hilbert space.
