Charmonium propagation through a dense medium

Coherent Neutrino Propagation in a Dense Medium

Motivated by the effect of matter on neutrino oscillations (the MSW effect) we have studied the propagation of neutrinos in a dense medium. The dispersion relation for massive neutrinos in a medium is known to have a minimum at nonzero momentum p ∼ GF ρ/ √ 2. We have studied in detail the origin and consequences of this dispersion relation for both Dirac and Majorana neutrinos both in a toy mod...

Doppler effects in the propagation of a few-cycle pulse through a dense medium.

This numerical study demonstrates that Doppler redshift exists in the reflected spectrum of a few-cycle pulse, propagating through a dense medium. It manifests itself in two different forms, a sharp low-frequency spike (LFS) located at the red edge of the reflected spectrum and a relatively broader redshift near the carrier frequency. With the variation of the laser and medium parameters, the d...

σ and ω meson propagation in a dense nuclear medium

Plane Wave Propagation Through a Planer Slab

An approximation technique is considered for computing transmission and reflection coefficients for propagation of an elastic pulse through a planar slab of finite width. The propagation of elastic pulse through a planar slab is derived from first principles using straightforward time-dependent method. The paper ends with calculations of enhancement factor for the elastic plane wave and it is s...

Propagation of a finite beam through a random medium.

The differential equation for the fourth-order statistical moment of the field of a finite beam propagating in a statistically homogeneous and isotropic two-dimensional random medium is solved numerically. Results are presented for the variance and covariance of irradiance scintillations of a Gaussian beam that propagates in a medium with a Gaussian correlation function. It is shown that the ra...
