- Abstract: The characteristics of nonstatic quantum light waves in the coherent state in
a static environment is investigated. It is shown that the shape of the wave
varies periodically as a manifestation of its peculiar properties of
nonstaticity like the case of the Fock-state analysis for a nonstatic wave. A
belly occurs in the graphic of wave evolution whenever the wave is maximally
displaced in the quadrature space, whereas a node takes place every time the
wave passes the equilibrium point during its oscillation. In this way, a belly
and a node appear in turn successively. Whereas this change of wave profile is
accompanied by the periodic variation of electric and magnetic energies, the
total energy is conserved. The fluctuations of quadratures also vary in a
regular manner according to the wave transformation in time. While the
resultant time-varying uncertainty product is always larger than (or, at least,
equal to) its quantum-mechanically allowed minimal value ($\hbar/2$), it is
smallest whenever the wave constitutes a belly or a node. The mechanism
underlying the abnormal features of nonstatic light waves demonstrated here can
be interpreted by the rotation of the squeezed-shape contour of the Wigner
distribution function in phase space.

As a light wave becomes nonstatic, an additional phase, the so-called geometric phase, takes place in its evolution.
As the wave becomes highly nonstatic, the phase factor of the electromagnetic wave evolves in a rectangular manner.
The electromagnetic field in this case very much resembles that of a standing wave.

Mean energy increases when the frequency returns to its initial value, and the increment coefficient is determined by the exponent in the power law of the frequency crossing zero.
If the frequency becomes imaginary, the absolute value of mean energy increases exponentially, even in the adiabatic regime.
Small corrections to the leading terms of simple adiabatic approximate formulas are crucial in this case, due to the unstable nature of the motion.

Atoms confined in a three-dimensional dissipative optical lattice oscillate inside potential wells, hopping to adjacent wells, thereby diffusing in all directions.
Illumination by a weak probe beam modulates the lattice, yielding propagating atomic density waves, referred to as Brillouin modes which travel perpendicular to the direction of travel of the probe.
A systematic measurement of the transmitted probe spectra as a function of off-axis probe angle is presented, which is consistent with the velocity- and frequency-matching predictions from the detailed model.

In two spatial dimensions, the symmetry of the box or microstrip antenna is an important feature that has often been overlooked in the literature.

The principle is to decompose the evolution of a quantum system into two wave functions.
For Schr"odinger, the particles are extended and the square of the module of the (internal) wave function of an electron corresponds to the density of its charge in space.
