# Bose-condensed atomic systems with nonlocal interaction potentials

@article{Yukalov2016BosecondensedAS, title={Bose-condensed atomic systems with nonlocal interaction potentials}, author={Vyacheslav I. Yukalov and E. P. Yukalova}, journal={Laser Physics}, year={2016}, volume={26} }

The general approach for describing systems with a Bose–Einstein condensate, where atoms interact through nonlocal pair potentials, is presented. Special attention is paid to nonintegrable potentials, such as the dipolar interaction potential. The potentials that are not absolutely integrable can have not well-defined Fourier transforms. Using formally these not defined Fourier transforms leads to unphysical conclusions. To make the Fourier transform well defined, the interaction potential has…
