Construction of a giant vortex state in a trapped Fermi system
Emil Lundh
A superfluid atomic Fermi system may support a giant vortex if the trapping potential is anharmonic. In such a potential, the single-particle spectrum has a positive curvature as a…
Dynamical stability of a doubly quantized vortex in a three-dimensional condensate
Emil Lundh, Halvor M. Nilsen
The Bogoliubov equations are solved for a three-dimensional Bose-Einstein condensate containing a doubly quantized vortex, trapped in a harmonic potential. Complex frequencies, sig…
One-dimensional extended Bose-Hubbard model with a confining potential: a DMRG analysis
Laura Urba, Emil Lundh, Anders Rosengren
The extended Bose-Hubbard model in a quadratic trap potential is studied using a finite-size density-matrix renormalization group method (DMRG). We compute the boson density profil…
Directed transport and Floquet analysis for a periodically kicked wavepacket at a quantum resonance
Emil Lundh
The dynamics of a kicked quantum mechanical wavepacket at a quantum resonance is studied in the framework of Floquet analysis. It is seen how a directed current can be created out…
