Discrete time-crystalline response stabilized by domain-wall confinement

M Collura, A De Luca, D Rossini, A Lerose - Physical Review X, 2022 - APS
Discrete time crystals represent a paradigmatic nonequilibrium phase of periodically driven
matter. Protecting its emergent spatiotemporal order necessitates a mechanism that hinders …

Trotter errors from dynamical structural instabilities of floquet maps in quantum simulation

K Chinni, MH Muñoz-Arias, IH Deutsch, PM Poggi - PRX Quantum, 2022 - APS
We study the behavior of errors in the quantum simulation of spin systems with long-range
multibody interactions resulting from the Trotter-Suzuki decomposition of the time-evolution …

Unified light-matter Floquet theory and its application to quantum communication

G Engelhardt, S Choudhury, WV Liu - Physical Review Research, 2024 - APS
Periodically driven quantum systems can exhibit a plethora of intriguing nonequilibrium
phenomena that can be analyzed using Floquet theory. Naturally, Floquet theory is …

Photon-resolved Floquet theory I: Full-Counting statistics of the driving field in Floquet systems

G Engelhardt, JY Luo, VM Bastidas… - arXiv preprint arXiv …, 2024 - arxiv.org
Floquet theory and other established semiclassical approaches are widely used methods to
predict the state of externally-driven quantum systems, yet, they do not allow to predict the …

Self-ordered time crystals: Periodic temporal order under quasiperiodic driving

S Choudhury, WV Liu - arXiv preprint arXiv:2109.05318, 2021 - arxiv.org
A discrete time crystal is a remarkable non-equilibrium phase of matter characterized by
persistent sub-harmonic response to a periodic drive. Motivated by the question of whether …
