WebMar 6, 2024 · Grand potential is defined by Φ G = def U − T S − μ N where U is the internal energy, T is the temperature of the system, S is the entropy, μ is the chemical potential, and N is the number of particles in the system. The change in the grand potential is given by d Φ G = d U − T d S − S d T − μ d N − N d μ = − P d V − S d T − N d μ When the system is in thermodynamic equilibrium, Φ G is a minimum. This can be seen by considering that dΦ G is zero if the volume is fixed and the temperature and chemical potential have stopped evolving. Landau free energy.
