Elasticity typically refers to a material's ability to store energy, whereas viscosity refers to a
material's tendency to dissipate it. In this review, we discuss fluids and solids for which this is …

The authors review the history, current status, physical mechanisms, experimental methods,
and applications of nonlinear magneto-optical effects in atomic vapors. They begin by …

Maxwell's equations, formulated 150 years ago, ultimately describe properties of light, from
classical electromagnetism to quantum and relativistic aspects. The latter ones result in …

The Hall effect usually occurs in conductors when the Lorentz force acts on a charge current
in the presence of a perpendicular magnetic field. Neutral quasi-particles such as phonons …

A random walk is a stochastic process in which particles or waves travel along random
trajectories. The first application of a random walk was in the description of particle motion in …

A tutorial discussion of the propagation of waves in random media is presented. To a first
approximation the transport of the multiple scattered waves is given by diffusion theory, but …

In the electrical Hall effect, a magnetic field, applied perpendicular to an electrical current,
induces through the Lorentz force a voltage perpendicular to the field and the current. It is …

It is unanimously accepted that the quantum and the classical descriptions of the physical
reality are very different, although any quantum process is" mysteriously" transformed …

The tunable refractive index of the magnetic fluid (MF) is a unique optical property, which
has attracted a lot of research interest in recent years. In this paper, a method based on the …

We discover a transition from extended to localized quasimodes for light in a gas of
immobile two-level atoms in a magnetic field. The transition takes place either upon …
