Pair correlations of scattered atoms from two colliding Bose-Einstein Condensates: Perturbative Approach
J. Chwedenczuk, P. Zin, M. Trippenbach +4
We apply an analytical model for anisotropic, colliding Bose-Einstein condensates in a spontaneous four wave mixing geometry to evaluate the second order correlation function of th…
Quantum phase transition and critical fluctuations of an attractive Bose gas in a double well potential
P. Ziń, J. Chwedeńczuk, B. Oleś +2
We consider a Bose gas with an attractive interaction in a symmetric double well potential. In the Hartree approximation, the ground state solution spontaneously breaks the symmetr…
Single quantum realization of a collision of two Bose--Einstein condensates
J. Chwedenczuk, P. Zin, K. Rzazewski +1
We propose a method for simulating a single realization of a collision of two Bose--Einstein condensates. Recently in Ziń {\it et al.} (Phys. Rev. Lett. {\bf 94}, 200401 (2005)) we…
Statics and dynamics of BEC's in double square well potentials
E. Infeld, P. Ziń, J. Gocałek +1
In this paper we treat the behavior of Bose Einstein condensates in double square well potentials, both of equal and different depths. For even depth, symmetry preserving solutions…
Elastic scattering losses from colliding BEC's
Pawel Zin, Jan Chwedenczuk, Marek Trippenbach
Bragg diffraction divides a Bose-Einstein condensate into two overlapping components, moving with respect to each other with high momentum. Elastic collisions between atoms from di…
Quantum multimode model of elastic scattering from Bose Einstein condensates
P. Zin, J. Chwedenczuk, A. Perez +2
Mean field approximation treats only coherent aspects of the evolution of a Bose Einstein condensate. However, in many experiments some atoms scatter out of the condensate. We stud…
