From stable periodic orbits to many-body chaos: doubly tunable prethermalization via engineering of an emergent band structure
Jianan Wang, Yang Hou, Andrea Pizzi +3
We uncover a family of many-body periodic orbits in a periodically driven (Floquet) spin system away from the high-frequency limit. While linear stability analysis predicts that pe…
Anomalous Floquet Heating from Sparse Long-Range Interactions
Chenyue Guo, Andrea Pizzi, Hongzheng Zhao
Regular lattices of interacting particles under a periodic drive typically heat with rate which is exponentially suppressed in drive frequency . Here…
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…
Genuine quantum scars in many-body spin systems
Andrea Pizzi, Long-Hei Kwan, Bertrand Evrard +2
Chaos makes isolated systems of many interacting particles quickly thermalize and forget about their past. Here, we show that quantum mechanics hinders chaos in many-body systems:…
Quantum many-body scars from unstable periodic orbits
Bertrand Evrard, Andrea Pizzi, Simeon I. Mistakidis +1
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…
