[超导国家重点实验室学术报告]晶格动力学中的量子几何效应

The wavefunction of phonons encodes rich quantum information, including topological and chiral properties. In phonon systems, “chirality” carries distinct meanings: topological chirality defined in k-space and rotational chirality associated with nonzero angular momentum. 

[超导国家重点实验室学术报告]Tailoring the Electronic Structure of Quantum Materials under Extreme Conditions

The ability to manipulate the electronic structure of quantum materials is pivotal to discovering emergent quantum phases and developing future quantum technologies. External tuning parameters-including dimensional confinement, electrostatic doping, and high magnetic fields-provide powerful and complementary means to engineer electronic states and uncovering their underlying properties.

[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
