特邀报告专家：北京高压科学研究中心、日本大阪大学Toshimori Sekine教授 时间：2026.8.25 下午 2:00-3:00 地点: 四川大学望江校区西五教319会议室 摘要：Recent advanced technologies of high-power lasers and related proving methods enable us to characterize the extreme states of shocked materials including warm dense matter. High power pulsed laser makes strong shock wave that achieves high pressure and high temperature state in nanoseconds and X-ray free electron lasers (XFELs) are extreme bright and short X-ray sources for understanding the shocked states. The shock compressed state is proved by optical methods to determined pressure, density, and temperature as well as some physical properties and atomic-level structural information. The results can be applied to simulate condensed matter physics and chemistry, natural impact conditions, and planetary interiors. My talk will introduce some recent experimental results and applications.  Recent selected publications: Y. Umeda, et al. (2026) Structural Evolution of Antigorite by High-Velocity Impacts. J.

题目： A Quantum Many-Body Waltz on the Poincaré Disk:Bose-Einstein Condensates with random interaction strength 报告人：刘明扬 博士（香港大学） 时 间：2026年07月23日（星期四）上午10:30-11:30 地 点：四川大学望江校区西五教学楼319会议室 报告摘要：In this talk, we investigate the dynamics of a uniform Bose-Einstein condensate with random interaction strength. We show that the system's dynamics can be mapped onto a stochastic flow on the upper sheet of the two-sheet hyperboloid, or equivalently, the Poincaré disk. On this manifold, the system admits a purely classical description in terms of the Poisson bracket defined on it. Under the weak-noise assumption, we derive analytic expressions for physical observables—such as the particle number—that agree well with numerical simulations. 报告人简介：Dr. Mingyang Liu works on ultra-cold atomic gases. He received his Bachler’s degree from Wuhan University in 2019, PhD degree from University of Hong Kong in 2023. Now, he is a postdoc researcher in University of Hong Kong. He did some work on p-wave Bose-Einstein condensate and three-body problem for fermions in 1D. Now his interest focuses on stochastic process in quantum many-body physics.

题目： Viscosity of one-dimensional Bose and Fermi gases 报告人：张世忠 教授（香港大学） 时 间：2026年07月23日（星期四）上午9:30-10:30 地 点：四川大学望江校区西五教学楼319会议室 报告摘要：I discuss bulk viscosity in one-dimensional Bose gas (Lieb-Liniger model) and also the spinless fermion gas with effective range corrections. In particular, we compute exactly the viscosity Drude weight using hydrodynamic projection within the framework of generalised hydrodynamics. I first argue that a properly definition of bulk viscosity Drude weight within GGE would render it identically zero. On the other hand, within the standard Gibbs ensemble, we found a nonzero Drude weight which is consistent with those computed from diagrammatic expansion, in addition to a few new results. 报告人简介：Professor Shizhong Zhang works on the general area of ultra-cold atomic gases. He received his Bachelor from Tsinghua University, Ph.D. from University of Illinois at Urbana-Champaign and did his postdoctoral training at The Ohio State University. He joined the University of Hong Kong in 2012. He did some early pioneer work on the universal properties of unitary Fermi gases and on the spin-orbit coupled quantum gases. His recent work focused on the transport properties of quantum gases, particularly with high-partial wave scattering.

报告题目: Atomistic Insights into Deep Planetary Materials: From Fast Ion Conduction to Acoustic Anelasticity 报  告 人：新加坡南洋理工大学理学院院长 Simon Redfern教授 报告时间: 2025年11月6日，上午10:30-11:30 报告地点：四川大学望江校区西五教 原子与分子物理研究所319会议室 摘要: Computational simulation provides a powerful means of linking atomic-scale processes to the macroscopic behaviour of planetary materials under extreme conditions. In this talk, I will survey recent work from the Environmental Materials Group at NTU Singapore exploring the structure, transport, and mechanical properties of minerals and alloys relevant to planetary interiors. These include computational structure prediction in the N–H–Si–O system, with implications for gas giant chemistry; modelling of p-block element alloying with iron to probe chalcophile–siderophile transitions at core conditions; and the role of ion mobility in governing mechanical response and acoustic attenuation in deep planetary materials. I will conclude by outlining emerging opportunities provided by machine learning and AI approaches for predicting and interpreting the properties of matter at planetary extremes.  报告人简介: Simon Redfern is Dean of the College of Science and President’s Chair in Earth Sciences at Nanyang Technological University, Singapore. Trained as a mineral physicist, his research lies at the intersection of solid-state physics, materials science, and geoscience, focusing on the behaviour of matter under extreme conditions. Before joining NTU, he was Professor and Head of Earth Sciences at the University of Cambridge. His recent work combines first-principles and atomistic simulations with experimental studies to probe dynamics, ionic transport, and elasticity in minerals and alloys—linking atomic-scale processes to the macroscopic properties of planetary interiors and functional materials on Earth.
