 Leviton (quasiparticle)

A **leviton** is a type of quasiparticle that arises in one-dimensional electrical systems, particularly in the context of quantum Hall effects and edge states of topological insulators. It is essentially a theoretical construct that represents a fractional excitation of an electron with well-defined properties, allowing for the transport of charge in quantized units. Specifically, levitons are created when an electron is injected into a one-dimensional conducting channel in such a way that it effectively behaves as a traveling wave packet.
