Quantum effect of inductance on geometric Cooper-pair transport
J. Salmilehto, M. Möttönen
We introduce a model for a flux-assisted Cooper-pair pump, the sluice, which is used to study geometric charge transport. Our model allows for a nonvanishing loop inductance going…
Vortex splitting and phase separating instabilities of coreless vortices in F=1 spinor Bose-Einstein condensates
M. Takahashi, V. Pietila, M. Mottonen +2
The low lying excitations of coreless vortex states in F = 1 spinor Bose-Einstein condensates (BECs) are theoretically investigated using the Gross-Pitaevskii and Bogoliubov-de Gen…
Stability of coreless vortices in ferromagnetic spinor Bose-Einstein condensates
V. Pietila, M. Mottonen, S. M. M. Virtanen
We study the energetic and dynamic stability of coreless vortices in nonrotated spin-1 Bose-Einstein condensates, trapped with a three-dimensional optical potential and a Ioffe-Pri…
Collapse and revival of excitations in Bose-Einstein condensates
M. Mottonen, S. M. M. Virtanen, M. M. Salomaa
We study the energies and decay of elementary excitations in weakly interacting Bose-Einstein condensates within a finite-temperature gapless second-order theory. The energy shifts…
