Classicalization of Quantum Variables and Quantum-Classical Hybrids
arXiv:1412.6321 · doi:10.1016/j.physleta.2015.06.031
Abstract
The extraction of classical degrees of freedom in quantum mechanics is studied in the stochastic variational method. By using this classicalization, a hybrid model constructed from quantum and classical variables (quantum-classical hybrids) is derived. In this procedure, conservation laws such as energy are maintained, and Ehrenfest's theorem is still satisfied with modification. The criterion for the applicability of quantum-classical hybrids is also discussed.
