Nonlinear behavior of bosons in anisotropic optical lattices
A. Cetoli, E. Lundh
We investigate the behavior of an array of Bose-Einstein condensate tubes described by means of a Bose-Hubbard Hamiltonian. Using an anisotropic non-polynomial Schrodinger equation…
Mott transition in anharmonic confinement
Emil Lundh
Two effects are identified that affect the visibility of the Mott transition in an atomic gas in an optical lattice confined in a power-law potential. The transition can be made mo…
Long term dynamics of the splitting of a doubly quantized vortex in a two-dimensional condensate
Halvor M. Nilsen, Emil Lundh
We study the nonlinear dynamics of the splitting of a doubly quantized vortex in a trapped condensate. The dynamics is studied in detail by solving the Gross-Pitaevskii equation. T…
Transition from a two-dimensional superfluid to a one-dimensional Mott insulator
Sara Bergkvist, Robert Saers, Emil Lundh +3
A two-dimensional system of atoms in an anisotropic optical lattice is studied theoretically. If the system is finite in one direction, it is shown to exhibit a transition between…
