Path Integral Ground State

First release of the Path Integral Ground State program.

Main features:

• Solves the many body Schrödinger equation for a system of bosons with periodic boundary conditions.
• Valid for arbitrary dimensions.
• WORM algorithm for the evaluation of the One Body Density Matrix.
• Evaluates the energy per particle using the mixed estimator and the thermodynamic estimator.
• Evaluates the pair distribution function.
• Evaluates the static structure factor.
• You can custom the system of study changing the system_mod.f90 module.
