This is a three-part text on the subject of superconductivity, an area of intense research activity worldwide. The first part covers the London, Pippard and Ginzburg-Landau theories, which are used to discuss a wide range of phenomena involving surface energies, vorticity, the intermediate and mixed states, boundaries and boundary conditions, the upper critical field in bulk, thin film and

In condensed matter physics, the resonating valence bond theory (RVB) is a theoretical model that attempts to describe high-temperature superconductivity, and in particular the superconductivity in cuprate compounds. It was first proposed by an American physicist P. W. Anderson and Indian theoretical physicist Ganapathy Baskaran in 1987. The theory states that in copper oxide lattices
material. At almost the same time, Anderson 8) proposed the mechanism of the high-tem-perature superconductivity based on the two-dimensional resonating valence band model. At that time, many scientists began to think that the superconductivity of Ba-doped La 2CuO 4 cannot be explained by the BCS theory. In February of 1987 Chu and others 9)
A generalization of the random-phase approximation of the theory of Coulomb correlation energy is applied to the theory of superconductivity. With no further approximations it is shown that most of the elementary excitations have the Bardeen-Cooper-Schrieffer energy gap spectrum, but that there are collective excitations also.
THEORY OF DIRTY SUPERCONDUCTORS P. W. ANDERSON Bell Telephone Laboratories, Murray Hill, New Jersey (Received 3 March 1959) Abstract B.C.S. type of theory (see BARDEEN, COOPER and SCHREIFFER, Phys. Rev. 108, 1175 (1957)) is sketched for very dirty superconductors, where elastic scattering from physical and chemical impurities is large compared …
P. W. Anderson, P. A. Lee, M. Randeria, T. M. Rice, N. Trivedi, F. C. Zhang One of the first theoretical proposals for understanding high temperature superconductivity in the cuprates was Anderson’s RVB theory using a Gutzwiller projected BCS wave function as an approximate ground state.

We consider a version of the symmetric Anderson impurity model (compactified) which has a non-Fermi-liquid weak-coupling regime. We find that in the Majorana fermion representation the perturbation theory can be conveniently developed in terms of Pfaffian determinants and we use this formalism to calculate the impurity free energy, self-energies, and vertex functions. To return to superconductivity, the claim of Sherman et al. 1 is that the Higgs mode is lowered below the double-gap threshold near the superconductor-insulator critical point, and that this
We provide and analyze a periodic Anderson model for studying magnetism and superconductivity in UTe2, a recently discovered candidate for a topological spin-triplet superconductor. The 24-band tight-binding model reproduces the band structure obtained from a DFT+U calculation consistent with an angle-resolved photoemission spectroscopy.

One theory for high- Tc superconductivity suggests the existence of chargons — the bosonic charge component of an electron — which can condense into a superconducting phase. Quantum spin.
