Decoherence, quantum-classical correspondence, and coherent control in molecular dynamics.
Written in English
Next, quantum-classical correspondence in intrinsic decoherence dynamics is examined via purities and reduced density matrices in both the position and energy representations. Dependence of the correspondence on the nature of the coupling potentials and on the initial conditions are discussed.Decoherence effects on quantum and classical dynamics in reactive scattering problems are investigated. Through the study of dynamics of the isotopic analogues of the collinear H + H2 reaction and transmission over simple one-dimensional barrier potentials, the role of decoherence in improving quantum-classical correspondence is identified with suppressing resonance and tunnelling.Finally, the efficiency of 1+3 photon phase control in the presence of decoherence effects phase is carefully examined in several model cases which include from a population inversion in a two-level bound system to IBr photodissociation. Further, the ways to overcome the control loss caused by dephasing are discussed.

This review focuses on quantum-classical Liouville dynamics, one of several quantum-classical descriptions, and discusses the problems that arise when one attempts to combine quantum and classical mechanics, coherence and decoherence in quantum-classical systems, nonadiabatic dynamics, surface-hopping and mean-field theories and their relation Cited by: 7. The tools needed to elucidate the quantum-to-classical transition via the process of decoherence—that is, turning a pure, or coherent, quantum state into a statistical mixture—involve a full arsenal of the typical features peculiar to quantum mechanics: superposition, entanglement, nonclassical correlations, superselection, and so by: 1.

Coherent Control, Quantum Chaos, and Decoherence in Molecular Dynamics Mensive coherent control of quantum chaotic diffusion in periodically kicked dynam- ics is demonstrated in both a paradigm of quantum chaos and molecuiar systems in pulsed microwave fields.
The origin of the control in deviations from random matrixAuthor: Jiangbin Gong. Abstract: The environment -- external or internal degrees of freedom coupled to the system -- can, in effect, monitor some of its observables.
As a result, the eigenstates of these observables decohere and behave like classical states: Continuous destruction of superpositions leads to environment-induced superselection (einselection).Cited by: III. Chaos and Loss of Correspondence A.

chaotic dynamics and decoherence, and most recently, the tantalizing glimpses of the information-theoretic nature of the quantum have elucidated our understanding of the Universe.
During this period, Los Alamos has grown into a leading center tives—not a coherent. Decoherence offers a theoretical framework in which the measurement problem can be swept under the carpet (pushed into a system larger than that which we can observe).
The effect is that quantum mechanics can be studied and presented to a student without the need for the ad hoc ``wave collapse'' being presented as a primary tool of the theory. the environment caused by; (a) “reduction of the state vector”, i.

Given a system with a limited number of degrees of freedom, together with its interaction with the environment; can one evaluate a critical time (decoherence time) within which the system behaves fully quantum mechanically (including Einstein-Podolsky-Rosen (EPR)—entanglements), and after which it displays quasi-classical features?Author: F.

Manipulation of quantum interference requires that the system under control remains coherent, avoiding (or at least postponing) the phase randomization that can ensue from coupling to an uncontrolled environment. We show that closed-loop coherent control can be used to mitigate the rate of quantum dephasing in a gas-phase ensemble of potassium dimers (K2), which acts as a model Cited by: The book is very comprehensive; I cannot recommend it as a good technical introduction into the subject, though.
Many important developments (such as integro-differential master equations, instanton formalism for decoherence) are not discussed, sometimes only mentioned, and there is way too much philosophy of quantum mechanics (about half of the pp book, by my estimation)/5.
