Nonstationary Selfconsistent Solutions in Quantum Field Theory
نویسنده
چکیده
Polaron problem is considered. Bogoliubov group variables for the spacetime translations group are defined. The scheme of secondary quantization for the scalar field interacting with charged quantum field is proposed. Scalar field is assumes to have nonzero classical component. Polaron is treated as a result of interaction of charged particle and neutral field classical component. The system state space is constructed. Expressions for integrals of motion in zero-point order with respect to inverted powers of coupling constant are given as a derivatives with respect to symmetry group generators.

Equivalent sets of solutions of the Klein-Gordon equation with a constant electric field
In connection with the problem of choosing the inand out-states among the solutions of a wave equation with one-dimensional potential we study nonstationary and ”stationary” families of complete sets. A nonstationary set consists of the solutions with the quantum number pv = p 0 v − p3. It can be obtained from the nonstationary set with quantum number p3 by a boost along x3-axis (along the dire...
متن کاملMoving Charges, Detectors and Mirrors in a Quantum Field with Backreaction
This is a progress report on our current work on moving charges[1, 2], detectors[3], and moving mirrors[4, 5] in a quantum field treated in a fully relativistic way via the Feynman-Vernon influence functional method[6], which preserves maximal quantum coherence of the system with selfconsistent back-reaction from the field.
متن کاملLight Propagation in Nonlinear Waveguide and Classical Two-Dimensional Oscillator
The quantum optical problem of the propagation of electromagnetic waves in a nonlinear waveguide is related to the solutions of the classical nonstationary harmonic oscillator using the method of linear integrals of motion [Malkin et.al., Phys Rev.2D (1970) 1371]. An explicit solution of the classical oscillator with a varying frequency, corresponding to the light propagation in an anisotropic ...
متن کاملModeling groundwater velocity uncertainty in nonstationary composite porous media
R R E C T E Summary Despite the intensive research over the past decades in the field of stochastic subsurface hydrology, our ability to analyze and model heterogeneous groundwater systems remains limited. Most existing theories are either too restrictive to handle practical complexity or too expensive to be applied to realistic problem sizes. In this paper we present approximate, closed-form e...
متن کاملQuantum Kinetic Theory for Laser Plasmas. Dynamical Screening in Strong Fields
A quantum kinetic theory for correlated charged-particle systems in strong time-dependent electromagnetic fields is developed. Our approach is based on a systematic gauge-invariant nonequilibrium Green's functions formulation. Extending our previous analysis [I] we concentrate on the selfconsistent treatment of dynamical screening and electromagnetic fields which is applicable to arbitrary none...
