Phase-matched four wave mixing and quantum beam splitting of matter waves in a periodic potential
Karen Marie Hilligsøe, Klaus Mølmer
We show that the dispersion properties imposed by an external periodic potential ensure both energy and quasi-momentum conservation such that correlated pairs of atoms can be gener…

Stability of gap solitons in a Bose-Einstein condensate
Karen Marie Hilligsoe, Markus K. Oberthaler, Karl-Peter Marzlin
We analyze the dynamical stability of gap solitons formed in a quasi one-dimensional Bose-Einstein condensate in an optical lattice. Using two different numerical methods we show t…
