The kinetic and interaction energies of a trapped Bose gas: Beyond the mean field
A. Yu. Cherny, A. A. Shanenko
The kinetic and interaction energies of a three-dimensional dilute ground-state Bose gas confined in a trap are calculated beyond a mean-field treatment. They are found to depend o…

Dilute Bose gas in two dimensions: Density expansions and the Gross-Pitaevskii equation
A. Yu. Cherny, A. A. Shanenko
A dilute two-dimensional (2D) Bose gas at zero temperature is studied by the method developed earlier by the authors. Low density expansions are derived for the chemical potential,…
