Metastability, chaos and spectrum tomography for Bose-Hubbard rings and chains
Rajat, Doron Cohen
We analyze the metastability of Bose-Hubbard condensates for finite-size one-dimensional ring lattices and open chains, using a semiclassical tomographic perspective that emphasize…
Mesoscopic superfluid to superconductor transition
Yehoshua Winsten, Doron Cohen
Spectrum tomography for the energy () of a ring-shaped Bose-Hubbard circuit is illustrated. There is an inter-particle interaction that controls superfluidity (SF) and the t…
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…
Quantum tomography of the superfluid-insulator transition for a mesoscopic atomtronic ring
Yehoshua Winsten, Doron Cohen
We provide a phase-space perspective for the analysis of the superfluid-insulator transition for finite-size Bose-Hubbard circuits. We explore how the eigenstates parametrically ev…
Quantum measurement of work in mesoscopic systems
Anant Vijay Varma, Doron Cohen
Heat and work in thermodynamics refer to the measurement of changes in energy content of external bodies (baths and agents). We discuss the implications of quantum mechanics on the…
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…
