# Hypergrid subgraphs and the origin of scarred quantum walks in the many-body Hilbert space

@inproceedings{Desaules2021HypergridSA, title={Hypergrid subgraphs and the origin of scarred quantum walks in the many-body Hilbert space}, author={Jean-Yves Desaules and Kieran Bull and Aiden Daniel and Zlatko Papi'c}, year={2021} }

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 systems. Here we explore the origin of scarred wavefunction revivals in a family of models obtained by deforming the graph adjacency matrix of the PXP model – the effective model of Rydberg atoms in the strong Rydberg blockade regime. We consider deformations that either enhance the Rydberg…

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.

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.
