Probing local relaxation of cold atoms in optical superlattices
A. Flesch, M. Cramer, I. P. McCulloch +2
In the study of relaxation processes in coherent non-equilibrium dynamics of quenched quantum systems, ultracold atoms in optical superlattices with periodicity two provide a very…
Exploring local quantum many-body relaxation by atoms in optical superlattices
M. Cramer, A. Flesch, I. P. McCulloch +2
We establish a setting - atoms in optical superlattices with period 2 - in which one can experimentally probe signatures of the process of local relaxation and apparent thermalizat…
Do mixtures of bosonic and fermionic atoms adiabatically heat up in optical lattices?
M. Cramer, S. Ospelkaus, C. Ospelkaus +3
Mixtures of bosonic and fermionic atoms in optical lattices provide a promising arena to study strongly correlated systems. In experiments realizing such mixtures in the quantum de…
Exact relaxation in a class of non-equilibrium quantum lattice systems
M. Cramer, C. M. Dawson, J. Eisert +1
A reasonable physical intuition in the study of interacting quantum systems says that, independent of the initial state, the system will tend to equilibrate. In this work we study…
Inhomogeneous atomic Bose-Fermi mixtures in cubic lattices
M. Cramer, J. Eisert, F. Illuminati
We determine the ground state properties of inhomogeneous mixtures of bosons and fermions in cubic lattices by studying the Bose-Fermi Hubbard model including parabolic confining p…
