Genuine quantum scars in Floquet chaotic many-body systems
Harald Schmid, Andrea Pizzi, Johannes Knolle
Unstable periodic orbits act as organizing structures for classical chaotic systems and underpin quantum scarring. Long known in single-particle systems, genuine quantum scars base…

Unstable periodic orbits galore and quantum hyperscarring in highly frustrated magnets
Andrea Pizzi, Claudio Castelnovo, Johannes Knolle
Highly frustrated magnets, with their macroscopically-degenerate classical ground states and massively-entangled quantum spin liquid phases, have been pivotal to the development of…

Quantum trails and memory effects in the phase space of chaotic quantum systems
Andrea Pizzi
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 su…
