Quantum thermalization and the route to ergodicity
Amichay Vardi, Doron Cohen
We consider a minimal model for quantum thermalization of coupled chaotic subsystems. The route towards ergodicity is explored as a function of the coupling strength. The results a…
Eigenstate thermalization to non-monotonic distributions in strongly-interacting chaotic lattice gases
Vladimir A. Yurovsky, Amichay Vardi
We find non-monotonic equilibrium energy distributions, qualitatively different from the Fermi-Dirac and Bose-Einstein forms, in strongly-interacting many-body chaotic systems. The…
Non-Conventional Thermal States of Interacting Bosonic Oligomers
Amichay Vardi, Alba Ramos, Tsampikos Kottos
There has recently been a growing effort to understand in a comprehensive manner the physics and intricate dynamics of many-body and many-state (multimode) interacting bosonic syst…
Many-body adiabatic passage: Instability, chaos, and quantum classical correspondence
Anant Vijay Varma, Amichay Vardi, Doron Cohen
Adiabatic passage in systems of interacting bosons is substantially affected by interactions and inter-particle entanglement. We consider STIRAP-like schemes in Bose-Hubbard chains…
Characterization of hybrid quantum eigenstates in systems with mixed classical phasespace
Anant Vijay Varma, Amichay Vardi, Doron Cohen
Generic low-dimensional Hamiltonian systems feature a structured, mixed classical phase-space. The traditional Percival classification of quantum spectra into regular states suppor…
Chaos and bi-partite entanglement between Bose-Joephson junctions
Amichay Vardi
The entanglement between two weakly coupled bosonic Josephson junctions is studied in relation to the classical mixed phasespace structure of the system, containing symmetry-relate…
