Nonlocal Theory of High-Temperature Superconductivity

Strong-coupling Theory of High-temperature Superconductivity

High-temperature superconductivity has transformed the landscape of solid state science, leading to the discovery of new classes of materials, states of matter, and concepts. However, despite being over a quarter of a century since its discovery, there is still no single accepted theory to explain its origin. This book presents one approach, the strong-coupling or bipolaron theory, which propos...

Half-Skyrmion theory for high-temperature superconductivity

We review the half-Skyrmion theory for copper-oxide high-temperature superconductivity. In the theory, doped holes create a half-Skyrmion spin texture which is characterized by a topological charge. The formation of the half-Skyrmion is described in the single hole doped system, and then the half-Skyrmion excitation spectrum is compared with the angle-resolved photoemission spectroscopy results...

Theory of high-temperature superconductivity and effective gravity

We argue that an approach involving effective gravity could play a crucial role in elucidating the properties of the high-temperature superconducting materials. In particular we propose that the high critical temperature might be naturally explained in a framework constructed as a direct condensed-matter analog of the RandallSundrum approach to a geometrization of the hierarchy problem in high-...
