蒋庆东，上海交通大学李政道研究所长聘教轨副教授。2017年在北京大学获得博士学位，师从谢心澄院士，之后在斯德哥尔摩大学进行博士后研究，师从诺贝尔奖得主Frank Wilczek。2021年起，回到上海交通大学李政道研究所工作至今。主要从事与手性相关量子现象的理论研究，在手性真空、手性物质以及二者相互作用理论方面有比较深入的研究，提出了手性卡西米尔效应、量子大气效应、手性Imbert-Fedorov 位移，以及手性超导的几何响应等多个新型量子效应。近年来，重点关注凝聚态理论与量子光学交叉方向，引领了利用对称性破缺微腔量子涨落来调控和设计原子、分子以及量子多体系统的能谱和拓扑特性的新方向。

Dr.Qingdong Jiang is a tenure-track associate professor at the Tsung-Dao Lee Institute, Shanghai Jiao Tong University. He received his Ph.D. from Peking University in 2017, under the supervision of Academician X. C. Xie. He then conducted postdoctoral research at Stockholm University, working with Nobel Laureate Frank Wilczek. Since 2021, he has been working at the Tsung-Dao Lee Institute, Shanghai Jiao Tong University. His primary research focuses on theoretical studies of quantum phenomena related to chirality. He has conducted in-depth research on chiral vacuums, chiral materials, and their interactions, proposing several novel quantum effects such as the chiral Casimir effect, quantum atmospheric effects, and the topological Imbert-Fedorov shift. In recent years, he has focused on the intersection of condensed matter theory and quantum optics, leading new directions in controlling and designing materials using symmetry-breaking microcavity quantum fluctuations.

讲座摘要/Abstract:

真空不“空”，真空中量子涨落是许多基本量子现象产生的根源，包括兰姆位移、自发辐射和卡西米尔效应等。根据量子力学理论，利用光学微腔可显著增强微腔内的量子涨落效应，从而使得由量子涨落引发的各种量子效应变得更加显著。近年来，众多实验已证明微腔量子涨落能够有效调控材料的量子特性。例如，真空微腔中的量子涨落已成功应用于调控非常规超导态、量子霍尔效应，以及金属-绝缘体相变等多种物理效应。本报告将与大家分享几种由对称性破缺与真空量子涨落联合作用产生的新型量子效应，包括：排斥性卡西米尔效应、量子大气效应、反常原子分子能谱、衍生Haldane模型、衍生手性自旋液体，量子霍尔效应，以及转角石墨烯的能带等。

Vacuum is far from a mere "void"; rather, it is filled with quantum fluctuations that serve as the foundation for many fundamental quantum phenomena, including the Lamb shift, spontaneous radiation, and the Casimir effect. According to quantum mechanics, optical microcavities can profoundly amplify these quantum fluctuations and enhance light-matter interactions. In recent years, a number of experimental evidence has shown that microcavity-induced quantum fluctuations can precisely control the quantum properties of materials, including their superconductivity, topological features, and quantum phase transitions. In this presentation, I will share our progress in the realm of cavity quantum materials, emphasizing the powerful synergy between symmetry breaking and vacuum fluctuations towards designing novel quantum effects.
