The grand potential
WebTo calculate the thermodynamic properties of a system of non-interacting fermions, the grand canonical partition function Zgr is constructed. The sum q runs over all of the possible macroscopic states, μ is the chemical potential, kB is Boltzmann's constant, and T is the absolute temperature. The energy and particle number of the macrostates ... WebThe grand potential plays a central role in adsorption thermodynamics. The grand potential is defined by Ω F i n iµ i PV (6) where F is the Helmholtz free energy. The independent variables of the grand potential are temperature, volume, and chemical potential. These variables are precisely the ones

WebValue of grand-potential at the initial point of the path. When the temperature of the initial point of the path is 0 K, the grand potential at a finite temperature evaluated using the low-temperature expansion should be used. The initial point of the path should be set to the finite temperature. Default : 0. Example : INITPOT = -0.016338475 WebOne can also introduce a new function of states, known as the The Grand Potential. It is built similarly to the way one built the Helmholtz function but this time by also making sure that the natural variable is the chemical potential (rather than the number of particles): ...
