[超导国家重点实验室学术报告]vdW magnet spintronics

Electrical control of quantum magnetic states is essential for both academic interest and next-generation spintronic device applications, which is one central focus of quantum materials and devices. Very recently, 2D van-der-Waals (vdW) magnetic materials have rapidly flourished to become star members in the field of 2D materials and device physics, providing enormous opportunities to open and advance diverse research directions from fundamental physics to device applications

[超导国家重点实验室学术报告]Symmetry Manipulation to Unlock Exotic Superconductivity对称性调控：迈向非常规超导

晶体结构及其对称性是决定材料物理性质的关键因素，这在过渡金属二硫族化合物（TMD）超导体中尤为突出。一方面，通过插层调控TMD的层间距，可在体相材料中实现二维超导；另一方面，调节TMD层间堆叠方式，则能诱导出反演对称性破缺的超导态，并伴随丰富的物理现象。此外，手性结构因缺乏镜像对称面与反演中心，同样可破坏空间反演对称性。因此，基于晶体结构对称性调控及手性结构体系的探索，是发现新颖超导物性的有效策略。

[超导基础理论和实验技术系列讲座 (一百三十二) ]从铜基、铁基和镍基超导体的共性谈非常规高温超导

Bardeen-Cooper-Schrieffer在1957年创立了著名的BCS理论，第一次让人类认识到超导发生的根本原因是电子系统配对以后发生凝聚，形成一个宏观量子相干态。该理论认为电子配对是通过交换虚声子而发生的，因此在该理论框架下高温超导就需要好的库伦屏蔽、高德拜温度和强的电声子耦合。

借助各种表界面超晶格的构造来实现新颖量子物态的构筑是近年来凝聚态物理研究中的热点问题。以石墨烯为代表，通过构造具有(√3×√3)R30°超晶格周期的凯库勒畸变（Kekulé-distortion）可以实现狄拉克锥向布里渊区中心折叠并打开能隙。本报告将介绍多种表界面元素掺杂方式实现石墨烯凯库勒超晶格的构筑与狄拉克电子调控。

[超导基础理论和实验技术系列讲座 (一百三十一) ]The Evolution of High-Temperature Superconductors: The "Bronze Age," "Iron Age," "Nickel Age," and Beyond

This presentation traces the historical development of high-temperature superconductors, focusing on significant materials classes such as cuprates, cobaltates, iron pnictides, chalcogenides, topological insulators, and nickelates.

[超导基础理论和实验技术系列讲座 (一百三十) ]Spin correlations in unconventional superconductors

Despite nearly four decades of intensive research on cuprate superconductors, the microscopic pairing mechanism responsible for high-temperature superconductivity remains elusive. This long-standing challenge has driven the search for copper-free unconventional superconductors, which can provide complementary insights and tighter constraints on the essential ingredients for high-Tc ​ pairing.

[超导国家重点实验室学术报告]Finite element models for superconducting systems

Given the recent improvements of their physical properties, high-temperature superconductors are increasingly used in many applications ranging from particle accelerators and fusion magnets, to electrical machines and power cables. 

[超导国家重点实验室学术报告]Magnetic landscape of superconducting resonators under radio-frequency excitation

Superconducting resonators are essential components in quantum circuits and highly sensitive sensors. However, their performance is often compromised by magnetic flux penetration, as the interaction of flux quanta and the induced radio-frequency (RF) currents in the superconducting thin film leads to significant energy dissipation. 

[超导基础理论和实验技术系列讲座 (一百二十九) ]ALCHEMY OF THE XXI CENTURY: DIGITAL SYNTHESIS OF QUANTUM MATERIALS

Atomic-layer-by-layer molecular beam epitaxy (ALL-MBE) is a new technique developed in the last few decades to synthesize functional quantum materials, including high-temperature superconductors (HTS), other complex oxides, and two-dimensional materials such as graphene and borophene. It also enables one to synthesize novel metastable materials that cannot be synthesized by standard methods. Several examples will be presented of ALL-MBE alchemy — the creation of artificial materials with novel and unique electronic properties. The ability to engineer the materials at a single-atomic monolayer level has also enabled important discoveries of novel physical phenomena and effects in HTS cuprates and beyond.
