simplesolv is a program to compute the solution of the equations of the Simplified approach to the Bose gas, as defined in [CJL19], [CJL20], [CHJL20].

simpleq v0.3 can be used to compute, among others:

- the solution, ground state energy, condensate fraction, momentum distribution and two-point correlation function for any equation in the Simplified approach, such as the Simple, Medium or Big equations, for any smooth potential.
- the solution, ground state energy and condensate fraction for the Simple equation with a hard core potential.

simpleq is written in Julia, and can run on any POSIX compliant system, including GNU/Linux and OSX, provided the Julia interpreter is installed. It requires the following Julia packages:
