Introduction to Unconventional Superconductivity
نویسنده
چکیده
This lecture gives a basic introduction into some aspects of the unconventional superconductivity. First we analyze the conditions to realize unconventional superconductivity in strongly correlated electron systems. Then an introduction of the generalized BCS theory is given and several key properties of unconventional pairing states are discussed. The phenomenological treatment based on the Ginzburg-Landau formulations provides a view on unconventional superconductivity based on the concept of spontaneous symmetry breaking. Finally some aspects of two examples of unconventional superconductors will be discussed: high-temperature superconductivity and spintriplet superconductivity in Sr2RuO4.

متن کاملSuperconducting materials classes: Introduction and overview
An introduction to and overview of the contents of this Special Issue are given. 32 classes of superconducting materials are discussed, grouped under the three categories ‘‘conventional’’, ‘‘possibly unconventional’’ and ‘‘unconventional’’ according to the mechanism believed to give rise to superconductivity. 2015 Published by Elsevier B.V.

Resonating valence bond states in a doped Mott insulator was proposed to explain superconductivity in cuprates in January 1987 by Anderson. A challenging task then was proving existence of this unconventional mechanism and a wealth of possibilities, with a rigor acceptable in standard condensed matter physics, in a microscopic theory and develop suitable many body techniques. Shortly, a paper...

To understand the mechanism of superconductivity in unconventional super onductors is one of the big challenges in the field of superconductivity. Based on the BCS theory, there is a direct relation between the pairing mechanism and the symmetry of the order parameter. Therefore, identification of the structure of the superconducting gap or the order parameter provides key information on the pa...
متن کاملSuperconductivity in ferromagnetic metals and in compounds without inversion centre
The symmetry properties and the general overview of the superconductivity theory in the itinerant ferromagnets and in materials without space parity are presented. The basic notions of unconventional superconductivity are introduced in broad context of multiband superconductivity which is inherent property of ferromanetic metals or metals without centre of inversion.
