Statistical mechanics of time independent nondissipative nonequilibrium states.
We examine the question of whether the formal expressions of equilibrium statistical mechanics can be applied to time independent nondissipative systems that are not in true thermodynamic equilibrium and are nonergodic. By assuming that the phase space may be divided into time independent, locally ergodic domains, we argue that within such domains the relative probabilities of microstates are g...
متن کاملRobustness of multiqubit entanglement in the independent decoherence model
We study the robustness of the Greenberger-Horne-Zeilinger “cat” class of multipartite states under decoherence. The noise model is described by a general completely positive map for qubits independently coupled to the environment. In particular, the robustness of N-party entanglement is studied in the large N limit when a the number of spatially separated subsystems is fixed but the size of ea...
متن کاملnon-corrective approach to pronunciation
the aim of this study has been to find answers for the following questions: 1. what is the effect of immediate correction on students pronunciation errors? 2. what would be the effect of teaching the more rgular patterns of english pronunciation? 3. is there any significant difference between the two methods of dealing with pronuciation errore, i. e., correction and the teaching of the regular ...
15 صفحه اولA random matrix approach to decoherence
In order to analyze the effect of chaos or order on the rate of decoherence in a subsystem, we aim to distinguish effects of the two types of dynamics by choosing initial states as random product states from two factor spaces representing two subsystems. We introduce a random matrix model that permits to vary the coupling strength between the subsystems. The case of strong coupling is analyzed ...
متن کاملDecoherence in Starobinsky Model
Starobinsky described an inflationary scenario in which quantum corrections to vacuum Einstein's equations drive the inflation. The quantum cos-mology of the model is studied by solving Wheeler-DeWitt equation. A connection between uncertainty requirement, randomness in initial states as well as curvature fluctuation is studied with a Schroedinger-type equation through a time parameter prescrip...
