Temporal fluctuations of correlators in integrable and chaotic quantum systems
Talía L. M. Lezama, Yevgeny Bar Lev, Lea F. Santos
We provide bounds on temporal fluctuations around the infinite-time average of out-of-time-ordered and time-ordered correlators of many-body quantum systems without energy gap dege…
Timescales of quantum and classical chaotic spin models evolving toward equilibrium
Fausto Borgonovi, Felix M. Izrailev, Lea F. Santos
We investigate quench dynamics in a one-dimensional spin model, comparing both quantum and classical descriptions. Our primary focus is on the different timescales involved in the…
Unitarity breaking in self-averaging spectral form factors
Apollonas S. Matsoukas-Roubeas, Mathieu Beau, Lea F. Santos +1
The complex Fourier transform of the two-point correlator of the energy spectrum of a quantum system is known as the spectral form factor (SFF). It constitutes an essential diagnos…
Quantum multifractality as a probe of phase space in the Dicke model
Miguel A. Bastarrachea-Magnani, David Villaseñor, Jorge Chávez-Carlos +3
We study the multifractal behavior of coherent states projected in the energy eigenbasis of the spin-boson Dicke Hamiltonian, a paradigmatic model describing the collective interac…
Periodically and quasiperiodically driven-anisotropic Dicke model
Pragna Das, Devendra Singh Bhakuni, Lea F. Santos +1
We analyze the anisotropic Dicke model in the presence of a periodic drive and under a quasiperiodic drive. The study of drive-induced phenomena in this experimentally accesible mo…
Quantum tunneling and level crossings in the squeeze-driven Kerr oscillator
Miguel A. Prado Reynoso, D. J. Nader, Jorge Chávez-Carlos +6
The quasi-energy spectrum recently measured in experiments with a squeeze-driven superconducting Kerr oscillator showed good agreement with the energy spectrum of its corresponding…
