Abstract: Using discrete molecular dynamics, we investigate the thermodynamical properties of a system interaction via ”Fermi-Jagla” pair potential, which is created by adding two Fermi distributions into ”Jagla” potential. Using this new potential with some certain parameters, we can get stable state with a lower temperature than that of the liquid-liquid critical poin (LLCP).We have successfully run constant-pressure simulations near the LLCP and confirm the negative slop of widom line.
