quasi-particle [¦kwä·zē ¦pard·ə·kəl]

(physics)

An entity used in the description of a system of many interacting particles which has particlelike properties such as mass, energy, and momentum, but which does not exist as a free particle; examples are phonons and other elementary excitations in solids, and “dressed” helium-3 atoms in Landau's theory of liquid helium-3.

Physicists discover novel electronic properties in 2D carbon structure by Asian News International Each chapter presents about 15-20 problems within a text explaining a particular topic, among them inter-atomic forces and lattice vibrations, density of states, thermodynamics of non-interacting quasi-particles, and interactions and phase transitions. Solid state physics; problems and solutions, 2d ed by SciTech Book News The electrons on the flat surface form a disorganized liquid sea of electrons, and if some extra electrons are then added, strange quasi-particles called anyons emerge.
