- Abstract: Motivated by the recent discovery of ergodicity breaking in geometrically
frustrated systems, we study the quench dynamics of interacting hardcore bosons
on a sawtooth ladder. We identify a set of initial states for which this system
exhibits characteristic signatures of localization like initial state memory
retention and slow growth of entanglement entropy for a wide parameter regime.
Remarkably, this localization persists even when the many-body spectrum is
thermalizing. We argue that the localized dynamics originates from an
interaction induced quantum interference. Our results show that the sawtooth
ladder can be a fertile platform for realizing non-equilibrium quantum states
of matter.

Isolated interacting quantum systems generally thermalize, yet there are several counterexamples for the breakdown of ergodicity.
Recently, ergodicity breaking has been observed in systems subjected to linear potentials, termed Stark many-body localization.
Here, we experimentally explore initial-state dependent dynamics using a ladder-type superconducting processor with up to 24 qubits.

We experimentally investigate non-equilibrium dynamics following rapid quenches in a many-body system composed of 3 to 200 strongly interacting qubits in one and two spatial dimensions.
We discover that scar revivals can be stabilized by periodic driving, which generates a robust subharmonic response akin to discrete time-crystalline order.
