Statistical inference in non-Hamiltonian dynamics
We assume that the formal results of the maximum-entropy approach for the description of some quantal systems remain valid in the presence of a perturbation that cannot be formulated in terms of a Hamiltonian, if the dynamical laws for a convenient set of observables are known. As an example we stud...

| Sumario: | We assume that the formal results of the maximum-entropy approach for the description of some quantal systems remain valid in the presence of a perturbation that cannot be formulated in terms of a Hamiltonian, if the dynamical laws for a convenient set of observables are known. As an example we study the harmonic motion of a quantal object coupled to a heat reservoir (a) reversibly and (b) irreversibly. In case (b), the data concerning the evolution of the individual fluctuations permit the construction of a density matrix for all times. © 1985 The American Physical Society. |
