Exactly solvable model of resonance tunneling of an electromagnetic wave in plasma containing shortscale inhomogeneities
Abstract
Different variants of resonance tunneling of a transverse electromagnetic wave through a plasma layer containing shortscale (subwavelength) inhomogeneities, including evanescence regions to which approximate methods are inapplicable, are analyzed in the framework of an exactly solvable onedimensional model. Complex plasma density profiles described by a number of free parameters determining the permittivity modulation depth, the characteristic scale lengths of plasma structures, their number, and the thickness of the inhomogeneous plasma layer are considered. It is demonstrated that reflectionfree propagation of the wave incident on the layer from vacuum (the effect of wavebarrier transillumination) can be achieved for various sets of such structures, including plasma density profiles containing a stochastic component. Taking into account cubic nonlinearity, it is also possible to obtain an exact solution to the onedimensional problem on the nonlinear transillumination of nonuniform plasma. In this case, the thicknesses of the evanescence regions decrease appreciably. The problem of resonance tunneling of electromagnetic waves through such barriers is of interest for a number of practical applications.

This paper considers the nonrelativistic Coulomb problem with shortrange interaction. The strong potential is modeled by a deltafunction interaction on a sphere r = r/sub 0/. Exact solutions to the Schroedinger equation are obtained for states with arbitrary angular momentum together with explicit analytic expressions for the scattering lengths, effective ranges, etc. The comparison of the exact solutions with the approximate formulas established earlier for arbitrary shortrange potential makes it possible to determine the limits of applicability of these approximations.

Exactly solvable model of two threedimensional harmonic oscillators interacting with the quantum electromagnetic field: The farzone CasimirPolder potential
We consider two threedimensional isotropic harmonic oscillators with the same frequency and interacting with the quantum electromagnetic field in the Coulomb gauge and within dipole approximation. Using a Bogoliubovtype transformation, we can obtain transformed operators such that the Hamiltonian of the system, when expressed in terms of these operators, assumes a diagonal form. We are also able to obtain an expression for the energy shift of the ground state, which is valid at all orders in the coupling constant. From this energy shift, the nonperturbative CasimirPolder potential energy between the two oscillators can be obtained. When approximated to the fourthmore » 
Interaction of attosecond electromagnetic pulses with atoms: The exactly solvable model
We consider the exactly solvable model of interaction of zeroduration electromagnetic pulses with an atom. The model has a number of peculiar properties which are outlined in the cases of a single pulse and two opposite pulses. In perspective, it can be useful in different fields of physics involving interaction of attosecond laser pulses with quantum systems. 
Exactly solvable wave equation with a linear confining potential I. Asymmetric model
A wave equation is presented which describes the confinement of a Dirac particle by means of a static linear potential. The model is exactly solvable and all solutions are tabulated. Also a complete set of commuting observables is given which can be used to characterize these solutions uniquely. The eigenvalues for the total angular momentum, j, and the energy squared, E/sup 2/, arrange themselves into linear and parallel Regge trajectories. Finally, a discussion is given of the highmass limit.
