Quantum many-body scars from unstable periodic orbits
Unstable periodic orbits (UPOs) play a key role in the theory of chaos, constituting the
“skeleton” of classical chaotic systems and “scarring” the eigenstates of the corresponding …

Periodic classical trajectories and quantum scars in many-spin systems
We numerically investigate the stability of exceptional periodic classical trajectories in rather
generic chaotic many-body systems and explore a possible connection between these …

Stabilizer Scars
Quantum many-body scars are eigenstates in non-integrable isolated quantum systems that
defy typical thermalization paradigms, violating the eigenstate thermalization hypothesis and …

Quantum trails and memory effects in the phase space of chaotic quantum systems
A Pizzi - arxiv preprint arxiv:2412.04310, 2024 - arxiv.org
The eigenstates of a chaotic system can be enhanced along underlying unstable periodic
orbits in so-called quantum scars, making it more likely for a particle launched along one …

Exploring the properties of quantum scars in a toy model
S Sinha, S Sinha - arxiv preprint arxiv:2411.03234, 2024 - arxiv.org
We introduce the concept of ergodicity and explore its deviation caused by quantum scars in
an isolated quantum system, employing a pedagogical approach based on a toy model …
