Zoo of quantum phases and excitations of cold bosonic atoms in optical lattices
Ofir E. Alon, Alexej I. Streltsov, Lorenz S. Cederbaum
Quantum phases and phase transitions of weakly- to strongly-interacting bosonic atoms in deep to shallow optical lattices are described by a {\it single multi-orbital mean-field ap…
On interacting fermions and bosons with definite total momentum
Ofir E. Alon, Alexej I. Streltsov, Lorenz S. Cederbaum
Any {\it exact} eigenstate with a definite momentum of a many-body Hamiltonian can be written as an integral over a {\it symmetry-broken} function . For two particles, we solve…
Continuous configuration-interaction for condensates in a ring
Ofir E. Alon, Alexej I. Streltsov, Kaspar Sakmann +1
A continuous configuration-interaction approach for condensates in a ring is introduced. In its simplest form this approach utilizes for attractive condensates the Gross-Pitaevskii…
