public class VirialHePCKLJSPYCorrection
Computes corrections to Percus-Yevick approximations of B4 and B5 for a helium pair potential.
Select the compressibility or virial route via boolean variable compressibility.
Use QFH boolean to change pair potential to the quadratic Feynman-Hibbs potential.
If determining which option is most efficient via short calculations to estimate standard error,
maintain a 50-50 split of steps between reference and target during data collection with
with adjustStepFreqFrequency = false;
