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…

Proposal for Realizing Quantum Scars in the Tilted 1D Fermi-Hubbard Model.
It is demonstrated that correlated fermions in tilted optical lattices provide a platform for understanding the interplay of many-body scarring and other forms of ergodicity breaking, such as localization and Hilbert space fragmentation.
Disorder-free localization and many-body quantum scars from magnetic frustration
Geometrical frustration has led to rich insights into condensed matter physics, especially as a mechansim to produce exotic low energy states of matter. Here we show that frustration provides a
Correspondence Principle for Many-Body Scars in Ultracold Rydberg Atoms
The theory of quantum scarring -- a remarkable violation of quantum unique ergodicity -- rests on two complementary pillars: the existence of unstable classical periodic orbits and the so-called
Quantum many-body scars from virtual entangled pairs
We study weak ergodicity breaking in a one-dimensional, nonintegrable spin-1 XY model. We construct for it an exact, highly excited eigenstate, which despite its large energy density, can be
Quantum Many-Body Scars: A Quasiparticle Perspective
Weakly interacting quasiparticles play a central role in the low-energy description of many phases of quantum matter. At higher energies, however, quasiparticles cease to be well-defined in generic
Exact many-body scars and their stability in constrained quantum chains
Quantum scars are non-thermal eigenstates characterized by low entanglement entropy, initially detected in systems subject to nearest-neighbor Rydberg blockade, the so called PXP model. While most of
Slow thermalization of exact quantum many-body scar states under perturbations
Quantum many-body scar states are exceptional finite energy density eigenstates in an otherwise thermalizing system that do not satisfy the eigenstate thermalization hypothesis. We investigate the
Hypergrid subgraphs and the origin of scarred quantum walks in many-body Hilbert space
Following the recent observation of wave function revivals in large Rydberg atom quantum simulators, much effort has focused on understanding the emergence of many-body scars in non-integrable
Quantum Many-Body Scars in Optical Lattices.
The dynamics are shown to be governed by kinetic constraints which appear via density-assisted tunneling in a high-frequency expansion and the optimal driving parameters for the kinetically constrained hopping are found which leads to small isolated subspaces of scared eigenstates.
Low-complexity eigenstates of aν= 1/3 fractional quantum Hall system
We identify the the ground-state of a truncated version of Haldane's pseudo-potential Hamiltonian in a thin cylinder geometry as being composed of exponentially many fragmented matrix product states.


Quantum many-body scars from magnon condensation
We study the eigenstate properties of a nonintegrable spin chain that was recently realized experimentally in a Rydberg-atom quantum simulator. In the experiment, long-lived coherent many-body
Exact Quantum Many-Body Scar States in the Rydberg-Blockaded Atom Chain.
It is shown that the nearby many-body scar states can be well approximated as "quasiparticle excitations" on top of the exact E=0 scar states and proposed a quasiparticles explanation of the strong oscillations observed in experiments.
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.
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
Periodic Orbits, Entanglement, and Quantum Many-Body Scars in Constrained Models: Matrix Product State Approach.
A manifold of locally entangled spin states is introduced, representable by low-bond dimension matrix product states, and it is found that they feature isolated, unstable periodic orbits, which capture the recurrences and represent nonergodic dynamical trajectories.
Dynamics and level statistics of interacting fermions in the lowest Landau level
We consider the unitary dynamics of interacting fermions in the lowest Landau level, on spherical and toroidal geometries. The dynamics are driven by the interaction Hamiltonian which, viewed in the
Beyond the Tao-Thouless limit of the fractional quantum Hall effect: spin chains and Fermi surface deformation
We discuss the relationship between the fractional quantum Hall effect in the vicinity of the thin-torus, a.k.a. Tao-Thouless (TT), limit and quantum spin chains. We argue that the energetics of
Geometric quench and nonequilibrium dynamics of fractional quantum Hall states
We introduce a quench of the geometry of Landau level orbitals as a probe of non-equilibrium dynamics of fractional quantum Hall states. The quench protocol can be experimentally implemented as a
Competing density-wave orders in a one-dimensional hard-boson model
We describe the zero-temperature phase diagram of a model of bosons, occupying sites of a linear chain, which obey a hard-exclusion constraint: any two nearest-neighbor sites may have at most one
Ising models of quantum frustration
We report on a systematic study of two-dimensional, periodic, frustrated Ising models with quantum dynamics introduced via a transverse magnetic field. The systems studied are the triangular and
