Quantum scars as embeddings of weakly broken Lie algebra representations
Recently, much effort has focused on understanding weak ergodicity breaking in many-body quantum systems that could lead to wavefunction revivals in their dynamics far from equilibrium. An example of
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
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.

Hypergrid subgraphs and the origin of scarred quantum walks in the 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 have extensive multipartite entanglement
Recent experimental observation of weak ergodicity breaking in Rydberg atom quantum simulators has sparked interest in quantum many-body scars – eigenstates which evade thermalisation at finite
