Classical equations for quantum systems.
The origin of the phenomenological deterministic laws that approximately govern the quasiclassical domain of familiar experience is considered in the context of the quantum mechanics of closed systems such as the universe as a whole. A formulation of quantum mechanics is used that predicts probabilities for the individual members of a set of alternative coarse-grained histories that decohere, w...
متن کاملClassical Analogs for Quantum Systems
The wave mechanics lives in a configuration space; the classical, hamiltonian mechanics in a phase space. This is but one of the difficulties faced by all the attempts of building a coherent interpretation of the quantum phenomena in terms of classical concepts. The prescription of the right extension procedures from one formulation to another will play, in fact, an essential role in the compre...
متن کاملOn Classical, Fuzzy Classical, Quantum and Fuzzy Quantum Systems
In this paper we consider physical systems and the concept of their states in the context of the theory of fuzzy sets and systems. In section 1 we give a brief sketch on the fundamental difference between the theories of classical physics and quantum mechanics. In section 2 and 3 we introduce very shortly systems and their states in classical and quantum mechanics, respectively. Section 4 prese...
متن کاملde Multi - time equations , classical and quantum
Motivated by relativity, several authors have suggested introducing, in classical and quantum physics, a separate time coordinate for every particle in order to avoid the use of simultaneity surfaces, e.g. [1–8]. For example, multi-time wave functions have been used in the foundations of quantum mechanics for defining relativistic collapse [9] or de Broglie–Bohm [10] theories. In quantum physic...
متن کاملQuantum Dynamical Entropies for Classical Stochastic Systems
We compare two proposals for the dynamical entropy of quantum deterministic systems (CNT and AFL) by studying their extensions to classical stochastic systems. We show that the natural measurement procedure leads to a simple explicit expression for the stochastic dynamical entropy with a clear informationtheoretical interpretation. Finally, we compare our construction with other recent proposals.
