Title: Electrodynamics of hidden quasiparticles and plasmons in nodal-metalsSpeaker: Yinming Shao (邵垠铭), Columbia UniversityTime: 4 pm, Jul 4th (Tuesday), 2023Location: 理科楼C302Abstract: The discovery of nodal-line semimetal ZrSiS extends the notion of Dirac fermions from points to lines and loops in the momentum space [1]. Identifying new nodal-line fermions is challenging since often the...

Title： Dimensional Reduction in the Presence of Quantum AgentsSpeaker: Prof. Mile Gu (Nanyang Technological University)Date and Time：2023年06月29日 10:00Location：培黎职业学院综合楼Abstract:Dimensionality reduction captures the spirit of Occam’s razor – asking the fundamental question: What features of current data are the essential indicators of future behaviour? By isolating such features...
