Threshold for Chaos and Thermalization in One-Dimensional Mean-Field Bose-Hubbard Model
Amy C. Cassidy, Douglas Mason, Vanja Dunjko +1
We study the threshold for chaos and its relation to thermalization in the 1D mean-field Bose-Hubbard model, which in particular describes atoms in optical lattices. We identify th…
Relaxation in a Completely Integrable Many-Body Quantum System: An Ab Initio Study of the Dynamics of the Highly Excited States of Lattice Hard-Core Bosons
Marcos Rigol, Vanja Dunjko, Vladimir Yurovsky +1
In this Letter we pose the question of whether a many-body quantum system with a full set of conserved quantities can relax to an equilibrium state, and, if it can, what the proper…
Interferometry in dense nonlinear media and interaction-induced loss of contrast in microfabricated atom interferometers
Maxim Olshanii, Vanja Dunjko
In this paper we update the existing schemes for computation of atom-interferometric signal in single-atom interferometers to interferometry with dense Bose-condensed atomic sample…
