It is shown that the local thermodynamic description of the ground state of a many-electron system, earlier proposed by Ghosh, Berkowitz and Parr, is equivalent to a well defined approximation for the density matrix and therefore for the Wigner's distribution.

The Wigner representation of a quantum state, corresponding to a classically integrable Hamiltonian, has been shown to be intimately tied to a classical phase space torus of the same energy. The fact that the semiclassical approximation of the Wigner function there derived turns out to be singular o
