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.

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 interacting system play the same role as the excited electrons (above the Fermi surface) and the excited holes (below the Fermi surface) in the IPA.

A quasiparticle is a collection of quantum characteristics among particles operating in their own, particle-like way. And unlike neutrons, protons, or even atoms and molecules, they aren't independent structures floating about on their own in free space.

2024年12月10日 · For the first time, scientists have observed a collection of particles, also known as a quasiparticle, that's massless when moving one direction but has mass in the other direction. The quasiparticle, called a semi-Dirac fermion, was first theorized 16 years ago, but was only recently spotted inside a crystal of semi-metal material called ZrSiS.

2024年1月7日 · In general, quasiparticles are groups of particles with quantifiable physical properties, and they don’t actually violate any fundamental physical principles — even if they often take those principles in unexpected directions.

The term Quasiparticle describes a concept in physics in which energetically excited states in matter are treated as though they are elementary quantum particles in their own right. In fact they may be something less tangible like a vibration or a rotation.

2024年12月17日 · Quasiparticle, in physics, a disturbance, in a medium, that behaves as a particle and that may conveniently be regarded as one. A rudimentary analogy is that of a bubble in a glass of beer: the bubble is not really an independent object but a phenomenon, the displacement of a volume of beer by

2014年11月4日 · 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 the many-body problem that arises from the messy interactions of real quantum particles.
