Dependence of pair correlation entropy, , and configurational energy, , on density, . The left panel shows results for silica at , 5500, 5000, 4500, and while the right panel shows isotherms for the 2SRP liquid at , 0.109, 0.082, 0.063, 0.045, 0.036, and 0.027 from top to bottom. The units of , , and are , , and for and , , and for the 2SRP system.
