New Approach for Stochastic Quantum Processes, their Manipulation and Control (2006)
The dissipation and decoherence (for example, the effects of noise in quantum computations), interaction with thermostat or in general with physical vacuum, measurement and many other complicated...
Regular and Chaotic Quantum Dynamic in Atom-Diatom Reactive Collisions (2006)
Gevorkyan, Ashot S., Bogdanov, Alexander V., Nyman, Gunnar
A new micro-irreversible 3D theory of quantum multichannel scattering in the three-body system is developed. The quantum approach is constructed on the generating trajectory tubes which allow taking...
Gevorkyan, Ashot S., Hu, Chin-Kun
A dielectric medium consisting of roughly polarized molecules is treated as a 3D disordered spin system (spin glass). A microscopic approach for the study of statistical properties of this system on...
Gevorkyan, Ashot S., Balint-Kurti, Gabriel G., Nyman, Gunnar
A new approach is described to the evaluation of the S-matrix in three-dimensional atom-diatom reactive quantum scattering theory. The theory is developed based on natural collision coordinates where...
New Perturbation Theory for Nonstationary Anharmonic Oscillator (1997)
Bogdanov, Alexander V., Gevorkyan, Ashot S.
The new perturbation theory for the problem of nonstationary anharmonic oscillator with polynomial nonstationary perturbation is proposed. As a zero order approximation the exact wave function of...
Bogdanov, Alexander V., Gevorkyan, Ashot S.
The system of oscillator interacting with vacuum is considered as a problem of random motion of quantum reactive harmonic oscillator (QRHO). It is formulated in terms of a wave functional regarded as...
Three Body Multichannel Scattering as a Model of Irreversible Quantum Mechanics (1997)
Bogdanov, Alexander V., Gevorkyan, Ashot S.
The new formulation of the theory of multichannel scattering on the example of collinear model is proposed. It is shown, that in the closed three-body scattering system the principle of quantum...
