Abstract Many of the static and dynamic properties of an atomic Bose–Einstein condensate (BEC) are usually studied by solving the mean-field Gross–Pitaevskii (GP) equation, which is a nonlinear partial differential equation for short-range atomic interaction. More recently, BEC of atoms with long-range dipolar atomic interaction are used in theoretical and experimental studies. For dipolar atomic interaction, the GP equation is a partial integro-differential equation, requiring complex algorithm for i... Title of program: (i) imag1d, (ii) imag2d, (iii) imag3d, (iv) real1d, (v) real2d, (vi) real3d Catalogue Id: AEWL_v1_0 Nature of problem These programs are designed to solve the time-dependent nonlinear partial differential Gross-Pitaevskii (GP) equation with contact and dipolar interactions in one, two or three space dimensions in a harmonic anisotropic trap. The GP equation describes the properties of a dilute trapped Bose-Einstein condensate.
