Generalized Gross-Pitaevskii Equation for 2D Bosons with Attractive Interactions

Author(s): Michał Suchorowski, Fabian Brauneis, Hans-Werner Hammer, Michał Tomza, and Artem G. Volosniev We introduce a generalized Gross-Pitaevskii equation that provides a nonlinear framework for studying 2D attractive Bose systems. Its defining feature is the logarithmic density dependence of the coupling constant, which breaks the scale invariance inherent in the standard mean-field equations. This… [Phys. Rev.
