Ultracold Bose gases in time-dependent 1D superlattices: response and quasimomentum structure
Markus Hild, Felix Schmitt, Ilona Türschmann +1
The response of ultracold atomic Bose gases in time-dependent optical lattices is discussed based on direct simulations of the time-evolution of the many-body state in the framewor…
Bose-Fermi mixtures in 1D optical superlattices
F. Schmitt, M. Hild, R. Roth
The zero temperature phase diagram of binary boson-fermion mixtures in two-colour superlattices is investigated. The eigenvalue problem associated with the Bose-Fermi-Hubbard Hamil…
Response of Bose gases in time-dependent optical superlattices
M. Hild, F. Schmitt, R. Roth
The dynamic response of ultracold Bose gases in one-dimensional optical lattices and superlattices is investigated based on exact numerical time evolutions in the framework of the…
Quantum phases of atomic boson-fermion mixtures in optical lattices
R. Roth, K. Burnett
The zero-temperature phase diagram of a binary mixture of bosonic and fermionic atoms in an one-dimensional optical lattice is studied in the framework of the Bose-Fermi-Hubbard mo…
Short-Range Correlations in He-4 Liquid and Small He-4 Droplets described by the Unitary Correlation Operator Method
R. Roth, H. Feldmeier
The Unitary Correlation Operator Method (UCOM) is employed to treat short-range correlations in both, homogeneous liquid and small droplets of bosonic He-4 atoms. The dominating sh…
