Physics When cuprate superconductors, which can conduct electricity without resistance up to temperatures on the order of 150 K, were first discovered almost 25 years ago, it was expected that the explanation for their extraordinary properties was around the corner and would lead to even higher transition temperatures T c.

Physicists are still searching for a convincing theory of high-temperature superconductivity. But at least the nature of the puzzle is becoming clearer. Mark Buchanan weighs the odds of a breakthrough in understanding.

The origin of the pseudogap in α-Ga
Journal of Physics: Condensed Matter, 2011Density functional theory, the free-electron empty lattice approximation and the nearly free-electron approximation are employed to investigate the electronic properties of partially covalent α-Ga. Whereas free-electron-like properties are revealed over a large energy range, a deep pseudogap at the Fermi level is characteristic of α-Ga.

Unlike conventional superconductors, the cuprate family of superconductors has an exotic phase above their transition temperature, Tc , where the material is neither superconducting nor in the normal state.

Pseudogap in the normal state of cuprates
Physica C: Superconductivity, 2000Abstract We show that underdoped cuprates are disordered materials with the diffusion coefficients of carriers as low as 10 −5 m 2 .s −1 . In these conditions Coulomb interaction between electrons must be taken into account. The main effect is to open a gap in the density of state (DOS) near the Fermi level (FL).

Abstract In this chapter, I explore some of the properties of the so-called pseudogapping construction. This construction is in important respects reminiscent of VP ellipsis, except that it leaves behind an element of the VP as a remnant.

The pseudogap state in high- superconductors
Physica A: Statistical Mechanics and its Applications, 2000Abstract We present two possible theoretical scenarios which may provide insight into the physics of the pseudogap state observed in underdoped cuprate superconductors.
