A direct approach to one photon interference contributions in the coherent control of photodissociation

چکیده
Formally exact quantum mechanical expressions for cumulative transition matrix elements m jk(j ,E)5(n^ j um«uE ,j ,n&^E ,j ,num«uk&, central to one photon coherent control scenarios of photodissociation, are derived. The resultant approach bypasses the need for solving the complete state-to-state quantum mechanical reactive scattering problem to obtain control results. These exact expressions are implemented both quantum mechanically and via a semiclassical initial value representation method to investigate coherent control in the generic photodissociation of a triatomic into more than one product. The semiclassical approach is shown to provide an accurate description of bimolecular control in this system. © 2001 American Institute of Physics. @DOI: 10.1063/1.1372713#

Coherent Transport of Single Photon in a Quantum Super-cavity with Mirrors Composed of Λ-Type Three-level Atomic Ensembles
In this paper, we study the coherent transport of single photon in a coupled resonator waveguide (CRW) where two threelevel Λ-type atomic ensembles are embedded in two separate cavities. We show that it is possible to control the photon transmission and reflection coefficients by using classical control fields. In particular, we find that the total photon transmission and reflection are achieva...
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 کاملAcquiring molecular interference functions of X-ray coherent scattering for breast tissues by combination of simulation and experimental methods
Background: Recently, it has been indicated that X-ray coherent scatter from biological tissues can be used to access signature of tissue. Some scientists are interested in studying this effect to get early detection of breast cancer. Since experimental methods for optimization are time consuming and expensive, some scientists suggest using simulation. Monte Carlo (MC) codes are the best...
متن کاملMultiphoton dissociation for coherent and incoherent fields.
The purpose of this work is to derive photodissociation probabilities in intense fields, corresponding to coherent and incoherent laser sources, in order to stress the importance of using the correct statistical averaging over photon source properties, when comparing theoretical results with experimental values. Molecular photodissociation by intense laser fields is being actively studied. New ...
متن کاملCoherent Control of Photocurrent in a Strongly Scattering Photoelectrochemical System
A fundamental issue that limits the efficiency of many photoelectrochemical systems is that the photon absorption length is typically much longer than the electron diffusion length. Various photon management schemes have been developed to enhance light absorption; one simple approach is to use randomly scattering media to enable broadband and wide-angle enhancement. However, such systems are of...
