[超导基础理论和实验技术系列讲座（六十九）] Vortices in superconductors: All the physics in a single grip

We discuss physics of Abrikosov vortices in type II superconductors. Abrikosov vortices, which are the topological excitations of the superconducting order parameter, exhibit a wealth of fascinating properties and phenomena. An interplay of vortex-vortex interactions, thermal fluctuations, and disorder leads to a rich phase diagram and novel phases: Bose and vortex glasses and vortex Mott state. In a glassy state, vortices exhibit nonlinear glassy dynamics, vortex creep. The correspondence between the quantum mechanics and statistical physics makes vortex systems a perfect and unique laboratory for studying many-body quantum strongly correlated systems, in particular out-of-equilibrium Mott transition which is hardly available by other means. In two dimensions vortices mediate Berezinskii-Kosterlitz-Thouless transition bringing a new paradigm, topological phase transition. The duality between vortices and Cooper pairs in two dimensions results in novel superinsulating and Bose-metal states. Finally, vortices became a platform for new development in physics: a non-Hermitian Hamiltonian theory of out of equilibrium phase transitions.

[超导国家重点实验室学术报告] Resonant Inelastic X-ray Scattering study of Magnetic Excitations in high-Tc cuprate superconductors

Resonant Inelastic X-ray Scattering (RIXS) is a photon-in and photon-out technique which becomes popular in recent years due to the fast progress in the instrumentation and by importanttheoretical achievements. RIXS can be used in a very effective way to study the charge and spin excitations in strongly correlated 3d transition-metal systems.

[超导国家重点实验室学术报告] Thin film deposition and high-field transport properties of Fe-based superconductors

The Fe-based superconductors (FBS) are very interesting materials both for basic research as well as in view of potential applications. FBS are unconventional, anisotropic, partially quantum-critical, multi-band superconductors, and all of these characteristics reflect to some extend in the electrical transport properties. They usually show very high upper critical fields and concurrent high irreversibility fields at low temperatures. This opens the possibility of high in-field critical current densities Jc, interesting especially for high-field applications.
