PSEUDOGAP Meaning and
Definition
-
The term "pseudogap" refers to a phenomenon observed in condensed matter physics, particularly in the study of superconductivity, that describes the suppression or partial disappearance of electronic states near the Fermi energy in certain materials.
In a conventional superconductor, the superconducting state is characterized by a complete energy gap in the electronic density of states below the Fermi energy. However, in some high-temperature superconductors or other strongly correlated systems, a pseudogap region is observed above the critical temperature, where the material is not in a superconducting state but displays similarities to it.
The pseudogap manifests as a partial or suppressed density of states, suggesting the formation of a new electronic phase or competing order that affects the behavior of the material. It is often accompanied by other anomalous properties, such as the temperature-dependent suppression of electrical conductivity and specific heat.
The exact nature of the pseudogap phenomenon remains a subject of ongoing research and debate. Various theories propose mechanisms such as the formation of charge order, spin fluctuations, or d-wave superconducting fluctuations as possible explanations. Understanding the origin and properties of the pseudogap is crucial for unraveling the complex behavior of high-temperature superconductors, as well as shedding light on the fundamental nature of quantum materials and their phase transitions.

Etymology of PSEUDOGAP
The term "pseudogap" is derived from the combination of two words: "pseudo" and "gap".
The word "pseudo" comes from the Greek word "pseudḗs" (ψευδής), meaning "false" or "lying". It is often used to denote something that imitates or resembles something else, but is not actually that thing. In the context of the "pseudogap", "pseudo" indicates that there is something resembling a gap, but it is not a true or complete gap.
The word "gap" refers to an opening or empty space. In science and physics, the term "gap" often refers to a range of forbidden energies in the electronic band structure of a material. In semiconductors or superconductors, there are energy gaps that separate filled states from empty states.
