Physical replicas and the Bose-glass in cold atomic gases
S. Morrison, A. Kantian, A. J. Daley +4
We study cold atomic gases in a disorder potential and analyze the correlations between different systems subjected to the same disorder landscape. Such independent copies with the…
Repulsively bound atom pairs: Overview, Simulations and Links
A. J. Daley, A. Kantian, H. P. Büchler +6
We review the basic physics of repulsively bound atom pairs in an optical lattice, which were recently observed in the laboratory, including the theory and the experimental impleme…
Repulsively bound atom pairs in an optical lattice
K. Winkler, G. Thalhammer, F. Lang +6
Throughout physics, stable composite objects are usually formed via attractive forces, which allow the constituents to lower their energy by binding together. Repulsive forces sepa…
Strongly correlated Fermi-Bose mixtures in disordered optical lattices
L. Sanchez-Palencia, V. Ahufinger, A. Kantian +3
We investigate theoretically the low-temperature physics of a two-component ultracold mixture of bosons and fermions in disordered optical lattices. We focus on the strongly correl…
Atomic Fermi-Bose mixtures in inhomogeneous and random lattices: From Fermi glass to quantum spin glass and quantum percolation
Anna Sanpera, Adrian Kantian, Laurent Sanchez-Palencia +2
We investigate atomic Fermi-Bose mixtures in inhomogeneous and random optical lattices in the limit of strong atom-atom interactions. We derive the effective Hamiltonian describing…
