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…
Second order quantum phase transition of a homogeneous Bose gas with attractive interactions
P. Ziń, B. Oleś, M. Trippenbach +1
We consider a homogeneous Bose gas of particles with an attractive interaction. Mean field theory predicts for this system a spontaneous symmetry breaking at a certain value of the…
Fock-space quantum particle approach for the two-mode boson model describing BEC trapped in a double-well potential
V. S. Shchesnovich, M. Trippenbach
We develop the Fock-space many-body quantum approach for large number of bosons, when the bosons occupy significantly only few modes. The approach is based on an analogy with the d…
Spontaneous symmetry breaking of gap solitons in double-well traps
M. Trippenbach, E. Infeld, J. Gocalek +3
We introduce a two dimensional model for the Bose-Einstein condensate with both attractive and repulsive nonlinearities. We assume a combination of a double well potential in one d…
