Vortices in rotating Bose–Einstein condensates confined in homogeneous traps

Rindler-Daller, T. - In: Physica A: Statistical Mechanics and its Applications 387 (2008) 8, pp. 1851-1874

We investigate analytically the thermodynamical stability of vortices in the ground state of rotating 2D Bose–Einstein … condensates confined in asymptotically homogeneous trapping potentials in the Thomas–Fermi regime. Our starting point is the Gross …

Finite temperature theory of metastable anharmonic potentials

Zoli, M. - In: The European Physical Journal B - Condensed Matter and … 62 (2008) 2, pp. 221-231

The decay rate for a particle in a metastable cubic potential is investigated in the quantum regime by the Euclidean path integral method in semiclassical approximation. The imaginary time formalism allows one to monitor the system as a function of temperature. The family of classical paths,...

Enhanced fluxon transmission through impurities

Zolotaryuk, Y. - In: The European Physical Journal B - Condensed Matter and … 62 (2008) 3, pp. 349-355

Fluxon transmission through several impurities of different strength and type (i.e., microshorts and microresistors), placed in a long Josephson junction is investigated. Retrapping current on the impurities is computed as a function of the distance between them, their amplitudes and the...
