[超导基础理论和实验技术系列讲座（九十）] 马衍伟：铁基超导线带材研究进展

Very high upper critical field and low anisotropy of iron-based superconductors (IBS) make them being particularly attractive for high-field applications, especially for the construction of nuclear magnetic resonance spectrometers, next-generation particle accelerators and ultra-high-field magnets.Conventional powder-in-tube method has been the most effective technique for fabricating IBS wires and tapes.Recently, significant progresses on the IBS wires have been made, in terms of both Jc enhancement and practical research. In this talk, the overview of the recent progress on Jc improvement and long wire fabrication will be provided.We also gives some advances relevant to practical applications, includingscalable process optimization, composite sheaths, multifilamentary fabrication, mechanical properties and superconductingjoints& coils

[超导基础理论和实验技术系列讲座（八十九）] The Advent of Two-dimensional Materials

Two-dimensional (2D) atomic crystals, best exemplified by graphene, have emerged as a new class of material that may impact future science and technology. 2D materials provides vast opportunities both on novel material properties that are different from those in the bulk, and better control of their material properties with external perturbations. In this talk I will illustrate a few examples ranged from semiconductors and high temperature superconductors. In particular, black phosphorus is a 2D semiconductor, and its superior material quality has recently enabled us to observe the quantum Hall effect; others include magnetic topological insulator and high temperature superconductor Bi2Sr2CaCu2O8+in the 2D limit. We explore their electronic properties while the doping and dimensionality of the 2D systems are modulated.

[超导基础理论和实验技术系列讲座（八十七）] Intertwined Orders in the Cuprate Superconductor and the Underlying Organization Principle

A sensible phenomenology of the complex phase diagram and rich phenomenon in the high-Tc cuprate calls for a microscopic understanding based on general principles. In this talk, I will identify a set of the most essential organization principles for the doped Mott insulator, which are argued to have captured the fundamental physics of the cuprate superconductor. Then I will exemplify their nature as the exotic long-range entanglement of many-body quantum mechanics by using the exact numerical tools of exact diagonalization and density matrix renormalization group, which are applied to some special cases of finite size/limited geometry to demonstrate the consequences of the general principle. Next, I will focus on the phase diagram relevant to the experiments in the cuprate, and show that it may be unified by a “parent”ground state ansatz constructed based on the organization principles. Here the superconducting state is of non-BCS nature with modified London equation and new elementary excitations. In particular, the two-gap structure and dichotomy between the nodal and antinodal regimes in the superconducting state, the origin of Fermi arc in the pseudogap regime, and the strange metal behavior in the high-temperature regime will be discussed as part of the emergent phenomenon.
