Quantum Magnetism with Mesoscopic Bose-Einstein Condensates
A. Gallemí, G. Queraltó, M. Guilleumas +2
Lattice gases in the strongly correlated regime have been proven to simulate quantum magnetic models under certain conditions: the mapping of the double-well system onto the Lipkin…
Multidimensional Josephson vortices in spin-orbit coupled Bose-Einstein condensates: snake instability and decay through vortex dipoles
A. Gallemí, M. Guilleumas, R. Mayol +1
We analyze the dynamics of Josephson vortex states in two-component Bose-Einstein condensates with Rashba-Dresselhaus spin-orbit coupling by using the Gross-Pitaevskii equation. In…
Coherent Quantum Phase Slip in two-component bosonic Atomtronic Circuits
A. Gallemí, A. Muñoz Mateo, R. Mayol +1
Coherent Quantum Phase Slip consists in the coherent transfer of vortices in superfluids. We investigate this phenomenon in two miscible coherently coupled components of a spinor B…
Persistent currents with non-quantized angular momentum
A. Muñoz Mateo, A. Gallemí, M. Guilleumas +1
We analyze the generation of persistent currents in Bose-Einstein condensates of ultracold gases confined in a ring. This phenomenon has been recently investigated in an experiment…
Phase-slips and vortex dynamics in Josephson oscillations between Bose-Einstein condensates
Marta Abad, Muntsa Guilleumas, Ricardo Mayol +3
We study the relation between Josephson dynamics and topological excitations in a dilute Bose-Einstein condensate confined in a double-well trap. We show that the phase slips respo…
