surfaceons

Surfaceons are hypothetical quasiparticles that are theorized to exist at the surface of certain materials. They are considered to be emergent phenomena arising from the collective behavior of electrons and atoms at the interface between a solid and its environment, such as a vacuum or another material. Unlike bulk phonons or magnons, surfaceons are localized to the surface and their properties are significantly influenced by the surface potential and termination.

The existence and properties of surfaceons are typically described within the framework of condensed matter physics. Their behavior can be studied using various spectroscopic techniques, including surface-sensitive electron energy loss spectroscopy (SEELFS) and scanning tunneling microscopy (STM). The energy and momentum of surfaceons are dependent on the specific material's surface structure, composition, and the nature of the surface reconstruction.

Research into surfaceons is motivated by their potential role in surface phenomena such as catalysis, friction, and adhesion. Understanding and controlling surfaceons could lead to advancements in materials science and nanotechnology. Theoretical models often employ concepts like surface phonons, surface plasmons, and surface magnons, which can be viewed as different types of surfaceons depending on the underlying excitations. The study of these quasiparticles helps to bridge the gap between microscopic quantum mechanical descriptions and macroscopic observable properties of materials.
