In condensed matter physics, a quasiparticle is a concept used to describe a collective behavior of a group of particles that can be treated as if they were a single particle.

quasiparticle, in physics, a disturbance, in a medium, that behaves as a particle and that may conveniently be regarded as one.

There is good theoretical (and experimen tal) evidence that these many-body states are well characterized in terms of a set of elementary excita tions, called quasi-particles, which for the …

A quasiparticle is a collection of quantum characteristics among particles operating in their own, particle-like way. Unlike fundamental bits of matter like electrons and quarks, quasiparticles aren't members …

The meaning of QUASIPARTICLE is a composite entity (such as a vibration in a solid) that is analogous in its behavior to a single particle.

Dec 1, 2016 · Landau's quasiparticles were elementary excitations of collections of particles. He suggested that these excitations could be treated as if they were particles themselves, with genuine …

Jan 1, 2024 · These particles, which he called quasiparticles, were excitations of the underlying quantum system that could be described by their own equations of motion. This was a major breakthrough in …

Enter the quasiparticle, a mathematical construct that makes near-impossible calculations not only possible, but also straightforward. Decades ago, researchers realized that they don't have to tackle …

A quasiparticle is defined as an emergent excitation in a condensed matter system that behaves like a particle and is not identical to the material's structural elements.
