Reversibility and Irreversibility within the Quantum Formalism
The discussion on time-reversal in quantum mechanics exists at least since Wigner’s paper [17] in 1932. If and how the dynamics of the quantum world is time-reversible has been the subject of many controversies. Some have seen quantum mechanics as fundamentally time-irreversible, see for example von Neumann [16, p. 358], and some have seen in that the ultimate cause of time’s arrow and second l...
متن کاملCoherent Control of Quantum Entropy via Quantum Interference in a Four-Level Atomic System
The time evaluation of quantum entropy in a four-level double- type atomic system is theoretically investigated. Quantum entanglement of the atom and its spontaneous emission fields is then discussed via quantum entropy. It is found that the degree of entanglement can be increased by the quantum interference induced by spontaneous emission. The phase dependence of the atom-field entanglement is...
متن کاملThe Quantum Formalism and the GRW Formalism
The Ghirardi–Rimini–Weber (GRW) theory of spontaneous wave function collapse is known to provide a quantum theory without observers, in fact two different ones by using either the matter density ontology (GRWm) or the flash ontology (GRWf). Both theories are known to make predictions different from those of quantum mechanics, but the difference is so small that no decisive experiment can as yet...
متن کاملInterplay of causticity and vorticality within the complex quantum Hamilton-Jacobi formalism
Interference dynamics is analyzed in the light of the complex quantum Hamilton-Jacobi formalism, using as a working model the collision of two Gaussian wave packets. Though simple, this model nicely shows that interference in quantum scattering processes gives rise to rich dynamics and trajectory topologies in the complex plane, both ruled by two types of singularities: caustics and vortices, w...
متن کاملFormalism in quantum mechanics
Formalism in quantum mechanics There are two neutral B 0 –B 0 meson systems, B 0 d –B 0 d and B 0 s –B 0 s (generically denoted B 0 q –B 0 q , q = s, d), which exhibit the phenomenon of particle-antiparticle mixing [1]. Such a system is produced in one of its two possible states of well-defined flavor: |B 0 (bq) or |B 0 (bq). Due to flavor-changing interactions, this initial state evolves into ...
