Stability and dynamics of vortex clusters in nonrotated Bose-Einstein condensates
V. Pietila, M. Mottonen, T. Isoshima +2
We study stationary clusters of vortices and antivortices in dilute pancake-shaped Bose-Einstein condensates confined in nonrotating harmonic traps. Previous theoretical results on…
Dynamically stable multiply quantized vortices in dilute Bose-Einstein condensates
J. A. M. Huhtamäki, M. Möttönen, S. M. M. Virtanen
Multiquantum vortices in dilute atomic Bose-Einstein condensates confined in long cigar-shaped traps are known to be both energetically and dynamically unstable. They tend to split…
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…
