According to van Leeuwen's theorem, when this state occurs in a magnetic system, all eddies must dissipate. As a consequence of ergodicity, the phase density of a system in this state is given by an arbitrary function of the Hamiltonian. In quantum mechanical systems, the existence of this condition is equivalent to the requirement that the time-derivative of the density matrix vanish. In addition
According to van Leeuwen's theorem, when this state occurs in a magnetic system, all eddies must dissipate. As a consequence of ergodicity, the phase density of a system in this state is given by an arbitrary function of the Hamiltonian. In quantum mechanical systems, the existence of this condition is equivalent to the requirement that the time-derivative of the density matrix vanish. In addition to CP violation and the existence of processes that violate baryon number, the non-existence of this state is necessary for baryogenesis, according to the Sakharov conditions. The transitivity of this state is expressed by the so-called zeroth law of thermodynamics. For 10 points, identify this steady state of a thermodynamic system in which the mean value of the system's temperature does not change with time.
