In poetry:

Carrier came down to the Loire and slew,
Till all the ways and the waves waxed red:
Bound and drowned, slaying two by two,
Maidens and young men, naked and wed.

In science:

When a sound wave travels in the metal, it gives rise to a collective motion of the charge carriers producing a self-consistent electromagnetic field accompanying the wave.
Electromagnetic quantum waves and their effect on the low temperature magnetoacoustic response of a quasi-two-dimensional metal
We showed that these “quantum waves” may occur at low temperatures and weak charge carriers scattering provided that the Fermi surface warping is rather pronounced (t > ωp0/q).
Electromagnetic quantum waves and their effect on the low temperature magnetoacoustic response of a quasi-two-dimensional metal
This shows that the quantum waves generated by combined effects of the lattice vibrations and the collective motions of charge carriers providing the electroneutrality of the whole system, are accompanied by magnetic oscillations of the longitudinal spin density.

On the other hand, when (as in gravitational-wave interferometers) the light consists of a monochromatic carrier plus signals encoded in side bands with frequency Ω = ω − ωo ≪ ωo , then for all practical purposes, ˆE (t) does self commute.

E ) is the wave function describing an incoming (or outgoing) carrier in contact α in channel m in the absence of a modulation potential, and Jl is the l’th order Bessel function.
Photon-assisted transport in semiconductor nanostructures
F is the carrier Fermi wave vector, h is the Planck constant, NM n the density of substitutional Mn, m∗ is the effective mass of the carrier, and e is the electron charge. χ⊥ = M /B and χI I = ∂M /∂B are the transverse and longitudinal magnetic susceptibilities.

At present, however, technology for creating very short pulses has advanced a lot and experiments with pulses which are as short as a few cycles of the carrier wave have become possible .
Ultra-short pulses in linear and nonlinear media
The main idea is that we assume a broad, rather than a short, pulse in the sense that we introduce time scales that are slower than the oscillations of the carrier wave that is oscillating at a fixed frequency ˜ω with a wavenumber ˜β .
Ultra-short pulses in linear and nonlinear media
Because of the oscillations of the carrier wave, in the Fourier domain the signal will be concentrated around the frequencies ˜ω and − ˜ω .

The idea is to encode data on top of a carrier wave composed of chaotic laser oscillations.

If the spectral width of the carrier wave ∆ωc is much smaller than the mode separation ωr , it represents a regularly spaced comb of laser modes just like (2), with identical spectral line shapes.

According to (3) each round trip will shift the carrier wave with respect to the envelope by ∆ϕ = arg(C (t − T )) − arg(C (t)) = ωcT so that the frequency offset may also be identified by ωCE = ∆ϕ/T (14; 34; 38).

The appearance of coherence factors u and v in the coefficients of the SM-EI junction demonstrates that the electron-hole condensate strongly affects the transport and in general the wave function of carriers, by means of both inducing coherence on the SM side and altering transmission features.
