03.03.2011. :: IPB seminar: Faraday waves in BEC, Alexandru Nicolin

 

U cetvrtak, 3. marta 2011. godine u biblioteci Instituta za fiziku sa pocetkom u 11 casova, odrzace se predavanje pod nazivom:

Faraday waves in Bose-Einstein condensates

koje ce odrzati Alexandru Nicolin (National Institute for Physics and Nuclear Engineering - NIPNE, Bucharest, Romania), gost SCL.


Abstract:
The presentation will survey the emergence of Faraday waves in Bose-Einstein condensates focusing on the experimental results of Engels et al. (Phys. Rev. Lett. 98, 095301) and the theoretical work of Nicolin et al. (Phys. Rev. A 76, 063609 and Physica A 389, 4663). Engels et al. have showed experimentally that an elongated high-density cigar-shaped condensate subject to periodic modulation of its transverse confinement excites small amplitude longitudinal oscillations through a parametric resonance, i.e., Faraday waves. In my talk I will give a complete analysis of the instability using an effectively one-dimensional model that captures the main features of the experimental results and will provide extensive three-dimensional numerical results.
