Atomc simulates atomic fluids with the Metropolis Monte Carlo
method, using force biased displacements, cavity-biased insertions
and virial biased volume changes.
Thermodynamic integration (TI)
integrands for the calculation of the excess free energy of the
Lennard-Jones fluid near its triple point.
The integration path was non-linear in the coupling parameter,
k is the exponent used for the different calculations.
