Conditions for order and chaos in the dynamics of a trapped Bose-Einstein condensate in coordinate and energy space
Roger R. Sakhel, Asaad R. Sakhel, Humam B. Ghassib +1
We investigate numerically conditions for order and chaos in the dynamics of an interacting Bose- Einstein condensate (BEC) confined by an external trap cut off by a hard-wall box…
Long-time averaged dynamics of a Bose-Einstein condensate in a bichromatic optical lattice with external harmonic confinement
Asaad R. Sakhel
The dynamics of a Bose-Einstein condensate are examined numerically in the presence of a one-dimensional bichromatic optical lattice with external harmonic confinement. The condens…
Properties of bosons in a one-dimensional bichromatic optical lattice in the regime of the Sine-Gordon transition: a Worm Algorithm Monte Carlo study
Asaad R. Sakhel
The properties of interacting bosons in a weak, one-dimensional, and bichromatic optical with a rational ratio of the constituting wavelengths and are numerically exami…
Self-interfering matter-wave patterns generated by a moving laser obstacle in a two-dimensional Bose-Einstein condensate inside a power trap cut off by box potential boundaries
Roger R. Sakhel, Asaad R. Sakhel, Humam B. Ghassib
We report the observation of highly energetic self-interfering matter-wave (SIMW) patterns generated by a moving obstacle in a two-dimensional Bose-Einstein condensate (BEC) inside…
Global and local condensate and superfluid fraction of a few hard core bosons in a cubic optical lattice plus external harmonic confinement
Asaad R. Sakhel
We explore the global and local condensate and superfluid (SF) fractions in a system of a few hard core (HC) bosons (N=8 and N=40) trapped inside a combined harmonic optical cubic…
Thermodynamic properties of an interacting hard-sphere Bose gas in a trap using the static fluctuation approximation
Saleem I. Qashou, Mohamed K. Al-Sugheir, Asaad R. Sakhel +1
A hard-sphere (HS) Bose gas in a trap is investigated at finite temperatures in the weakly-interacting regime and its thermodynamic properties are evaluated using the static fluctu…
