A new method for the estimation of chemical potential in molecular simulation
the Reference Test Particle method
is proposed. This method is more efficient than the particle-insertion method and overcomes the drawback of underestimate obtained with the particle-removal method. Application of the new method to hard sphere fluids at ρσ3 = 0.50 and o.65 and Lennard-Jones fluids at ρσ3 = 0.65
0.70
0.80 and o.90 along the isotherm kT/ ε= 1.2 shows that the RTP method has the advantages of fast convergence
