Dynamics, quantum states and Compton scattering in nonlinear gravitational waves

Journal of High Energy Physics
The classical dynamics and the construction of quantum states in a plane wave curved spacetime are examined, paying particular attention to the similarities with the case of an electromagnetic plane wave in flat spacetime.

Specifics of magnetotelluric studies in Antarctica

Записки Горного института
One of the priority areas of scientific research in Antarctica is the study of its deep structure. Most of the continent is covered with a thick ice sheet, so the main geoscientific data are acquired using geophysical methods, among which magnetotelluric

Diffraction by an impedance half-plane dependence on the impedance parameter

Archives of Acoustics, 2014
The problem of plane wave diffraction by an impedance half-plane is considered. The aim of the paper is to analyze how the solution depends on the complex impedance parameter. The Senior solution is analytically continued from real positive values of the

Inhomogeneous Plane Waves

Archive for Rational Mechanics and Analysis, 1984
After an extended survey of the Gibbs-Synge theory of bivectors (complex vectors) the paper uses that theory to find results on the polarization of inhomogeneous plane waves. The link between bivectors and plane waves is that the field (e.g. displacement u or electric field E) corresponding to a train of such waves is described in terms of two ...

Multipole expansion of a plane wave

Journal of Mathematical Physics, 2002
The spherical components of the multipole expansion of a plane wave with arbitrary spin are obtained in terms of spin-weighted spherical harmonics. It is shown that the expansion coefficients are essentially spin-weighted spherical harmonics evaluated at the direction of propagation of the wave.

Colliding almost-plane gravitational waves: Colliding plane waves and general properties of almost-plane-wave spacetimes

Physical Review D, 1988
It is well known that when two precisely plane-symmetric gravitational waves propagating in an otherwise flat background collide, they focus each other so strongly as to produce a curvature singularity. This paper is the first of several devoted to almost-plane gravitational waves and their collisions.

Stability of Periodic Plane Waves

SIAM Journal on Applied Mathematics, 1987
Given a nonlinear partial differential equation for which an explicit solution is known, standard linear stability theory can be used to study the stability of such a solution by determining the variational equation obtained by linearizing the given equation about the solution. This method is applied to explicit plane wave solutions of the Schrödinger,
