Example sentences
The particles associated with excitations of the electro-magnetic field are photons, and the particles associated with excitations of this deformation field are called phonons.
The idea is that in a quantum many-body system, a (low-energy) state can often be represented as a set of independent excitations of the field, which are called quasiparticles.
Nothing really beyond some local excitations of electrical fields and EM waves in certain frequency range.
In quantum field theory, the fundamental spacetime entity is a field, and quantized excitations of the field are interpreted as particles.
Aside from tiny losses like tunnelling, scattering from vacuum excitations and thermally-generated fields, etc., a perfect optical cavity will store light indefinitely.
In particular, the fractional quantum states/excitations aspect was completely missing in the Extremetech article.
They aren't excitations of individual electrons, but of the system as a whole.
These are not assumed particles, but natural excitations of a foundational harmonic field, much as photons arise from vibrations in the electromagnetic field.
Both electrons and electron holes are just excitations in a quantum field anyway...
CIE XYZ accounts for this by projecting SML excitations down to a 2D plane (XY) and making the third dimension a color-independent luminosity (Z).
When cooled to temperatures near absolute zero and exposed to strong magnetic fields, excitations form in the 2-D electron gas and give rise to anyons.
And then the particles are actually merely excitations of a field.
Quote examples
They are more like "particle analogs", which exist as excitations of some underlying matter.
Can anyone explain the significance of "a state with fractionalized excitations?"
Frenkel (1894-1952) developed his notion of “holes” and “collective excitations” in condensed-matter physics through extensive reflection on contemporary Soviet political thought.
"Particle analogs" are "excitations in the state of some underlying matter", but the underlying matter is just excitations in the state of some underlying wave function.
Proper noun examples
Excitations of this field look suspiciously similar to a particle, as in they are produced by the same mathematical formalism.
