basic page

New page

This page is mostly a long list of links to wikipedia. But there'll be a focus on:
* eventual practical applicability in small devices outside of highly specialized labs (avoiding nano kelvin only phenomena)
* relation to [[APM]] and [[gem-gum-tec]]
* less exotic stuff first
* giving a better overview than otherwhere exists (more than just a long list)

From the "Surface magnon polariton" page. See further down.

== Spinons, Orbitons, Holons ==

These three are interlinked originating from a single splitup but sometimes able to act independently. To check.

= Interaction based quasiparticles =

Adding interactions means there is a bit of a '''combinatoric explosion''' and thus a whole zoo of subtype-quasiparticles.

== Polarons (fermionic, various types of these) ==

Not to confuse with plaritons! 
See: [https://en.wikipedia.org/wiki/Polaron Polaron]

Wikipedia: "… describe an electron moving in a dielectric crystal where the atoms displace from their equilibrium positions to effectively screen the charge of an electron, known as a phonon cloud. This lowers the electron mobility and increases the electron's effective mass."

Wikipedia: "acoustic polaron, piezoelectric polaron, electronic polaron, bound polaron, trapped polaron, spin polaron, molecular polaron, solvated polarons, polaronic exciton, Jahn-Teller polaron, small polaron, bipolarons and many-polaron systems."

Wikipedia: "The possibility that polarons and bipolarons play a role in high-temperature superconductors has renewed interest in the physical properties of many-polaron systems and, in particular, in their optical properties."

'''This seems to be linked to the bounding mechanism in cooper pairs. To check.'''

== Polaritons (bosonic, various types of these) ==

Wikipedia: "… strong coupling of electromagnetic waves with an electric or magnetic dipole-carrying excitation." 
EM + exctitons or plasmons or ionic-crystal-phonons or magnons or ...
