Isoenthalpic–isobaric ensemble : ウィキペディア英語版 | Isoenthalpic–isobaric ensemble
The isoenthalpic-isobaric ensemble (constant enthalpy and constant pressure ensemble) is a statistical mechanical ensemble that maintains constant enthalpy and constant pressure applied. It is also called the -ensemble, where the number of particles is also kept as a constant. It was developed by physicist H. C. Andersen in 1980.〔Andersen, H. C. ''Journal of Chemical Physics'' 72, 2384-2393 (1980).〕 The ensemble adds another degree of freedom, which represents the variable volume of a system to which the coordinates of all particles are relative. The volume becomes a dynamical variable with potential energy and kinetic energy given by .〔Hwee, Chiang Soo. ("Mechanical behavior of peptides in living systems using molecular dynamics." )〕 The enthalpy is a conserved quantity.〔(Other Statistical Ensembles )〕 == References == 〔
