[超导国家重点实验室学术报告]Disorder as a tuning knob of the phase diagram of Iron-based superconductors

n doped Hund’s metals, such as the iron-based superconductors (FeSCs), effects like charge doping and chemical pressure are often considered the dominant factors. Partial chemical substitution, however, inevitably introduces disorder.

[超导国家重点实验室学术报告]Uniaxial strain tuning of dynamics in quantum materials

Uniaxial strain is an increasingly important tuning parameter in the physics of quantum materials, and in the past decade it has been used to study and manipulate both electronic and structural ordering phenomena in a wide range of systems.

[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.
