A General Conceptual Framework for Decoherence in Closed and Open Systems
نویسندگان
چکیده
In this paper we argue that the formalisms for decoherence originally devised to deal just with closed or open systems can be subsumed under a general conceptual framework, in such a way that they cooperate in the understanding of the same physical phenomenon. This new perspective dissolves certain conceptual difficulties of the einselection program but, at the same time, shows that the openness of the quantum system is not the essential ingredient for decoherence.

A general theoretical framework for decoherence in open and closed systems
A general theoretical framework for decoherence is proposed, which encompasses formalisms originally devised to deal just with open or closed systems. The conditions for decoherence are clearly stated and the relaxation and decoherence times are compared. Finally, the spin-bath model is developed in detail from the new perspective.

متن کاملDecoherence: A Closed-System Approach
The aim of this paper is to review a new perspective about decoherence, according to which formalisms originally devised to deal just with closed or open systems can be subsumed under a closed-system approach that generalizes the traditional account of the phenomenon. This new viewpoint dissolves certain conceptual difficulties of the orthodox open-system approach but, at the same time, shows t...
متن کاملBuilding a Comprehensive Conceptual Framework for Power Systems Resilience Metrics
Recently, the frequency and severity of natural and man-made disasters (extreme events), which have a high-impact low-frequency (HILF) property, are increased. These disasters can lead to extensive outages, damages, and costs in electric power systems. A power system must be built with “resilience” against disasters, which means its ability to withstand disasters efficiently while ensuring the ...
متن کاملDevelopment of a conceptual model for asthma management system in primary care
Introduction: Asthma is uncontrolled in more than half of asthma patients due to inadequate and incorrect management. The main reasons for inadequate management are non-adherence, inadequate knowledge of a general practitioner about patientchr('39')s clinical condition, and not following asthma management guidelines The purpose of this study was to develop a conceptual model for the asthma mana...
