2023-10物理学院学术论坛（第二十八讲）：35 Years of In Situ X-ray Scattering Studies of Crystal Surfaces During Growth
报告摘要: This year marks the 110th anniversary not only of Physics at Peking University, but also the discovery of X-ray diffraction by crystals. Since the advent of synchrotron sources, in situ X-ray scattering from surfaces has become a powerful probe to observe the atomic-scale mechanisms of epitaxial film growth. I will present highlights of such studies from the work of our group and othe...

2023-09物理学院学术论坛（第二十七讲）：Metasurfaces for controlling light
报告摘要: Metasurfaces are ultra-thin metamaterials composed by planar meta-atoms arranged in specific macroscopic orders, which exhibit strong capabilities to control light [1-2]. In this Colloquium, I will present a brief overview on the historical development of this fast-developing research field, focusing particularly on our recent efforts in employing meta-surfaces to control light in var...

2023-09物理学院学术论坛（第二十六讲）：The Little Bang Standard Model
报告摘要: The Little Bangs created in ultra-relativistic heavy-ion collisions share many characteristic features with the cosmological evolution after the Big Bang. They create a quark-gluon plasma - an extremely dense state of strongly interacting matter that flows like an almost perfect fluid. This allows to describe such heavy-ion collisions with dissipative relativistic fluid dynamics, sup...

2023-06北京大学格致论坛（第十六讲）：癌症转移的诊断和治疗
主要内容： 癌症与每一个家庭息息相关。当前临床90%癌症患者死亡的原因是转移。传统的手术和放化疗等主流治疗手段通常仅对未转移肿瘤有较好控制效果，对已转移的肿瘤则往往疗效不佳。2018年诺贝尔医学奖授予了癌症免疫检查点治疗，尽管该方法适用范围有限、有效率不高且副作用较大，但却让人类首次看到了治愈已转移癌症的一丝曙光。如何从更底层去理解转移的物理学基础、进而通过对物理规律的解析以应对癌症的转移，既是当前全...

2023-06物理学院学术论坛（第二十三讲）：NEW HEAVY EXOTICS
报告摘要: Quarks are the point-like fundamental building blocks of hadrons, strongly-interacting particles. Quarks were first suggested by Gell-Mann and Zweig, to explain patterns observed in the hadronic spectra. Their existence has since been conclusively established by a series of subsequent beautiful experiments, recognized by several Nobel Prizes. Quarks are confined into hadrons by the st...

2023-05物理学院学术论坛（第二十二讲）：Voltage Control of Quantum Phase of Matter
报告摘要: Condensed matter, due to its large number of atoms, exhibits a variety of unexpected quantum phases, including superconductivity, magnetism, correlated insulators, and ferroelectrics, and topological phases. In this lecture, I will give a brief review on the electric field (and more broadly voltage) control of quantum matter, with particular interest in two-dimensional van der Waals m...
