SUMMARY:Séminaire du LPTMS: Haggai Landa - LPTMS\, salle 201\, 2ème étag
 e\, Bât 100\, Campus d'Orsay - 12 Jan 16 11:00
DESCRIPTION:Quasi-bound states in periodically driven scattering\n\nHaggai 
 Landa (LPTMS)\n\nI will discuss the interaction of a cold atom co-trapped 
 with an ion in a Paul trap\, a platform which in recent years promises to 
 make possible investigations of ion-neutral interactions in the ultracold 
 regime. The main theoretical and experimental difficulty in this system is
  due to the time dependence of the ion trap\, which is periodically modula
 ted by an AC voltage. We present a general approach for obtaining eigenfun
 ctions of periodically driven time-dependent Hamiltonians and derive an ex
 plicit expansion for scattering problems with mixed cylindrical and spheri
 cal symmetry [1]. Using this method we study quasi-bound states of a spher
 ically-symmetric potential in three dimensions subject to an axial driving
  force. The analysis of the ion-atom system is completed by solving self-c
 onsistently the time-dependent wavefunctions of the atom together with the
  periodic force it exerts on the ion [2].\n[1]     H. Landa\, arXiv:
