SUMMARY:Quantum simulation of topological phenomena in dynamic systems
DESCRIPTION:\nTime：10:00am (UTC/GMT+8:00, Beijing/Shanghai), Apr. 21 (Wed.), 2021\n\n\n\nVenue: KITS Meeting Room, 4th floor, No. 7 Building, UCAS [View Map ( https://kits.ucas.ac.cn/index.php/about/location )]\n\n\n\nSpeaker: Ling-Yan Hung (Fudan University)\n\n\n\nSpeaker: Qian-Qian CHEN (HUST)\n\n\n\nAbstract:With the development of topological physics, the search for topological structures has not been limited to condensed matter systems. Synthetic quantum systems, such as ultracold atomic gases and nitrogen-vacancy centers in diamond, with less influence from impurities, are much more controllable, enabling the realization and observation of many novel topological phenomena. In synthetic quantum systems, dynamical modulation is one of the most common methods used to simulate topological structures and phenomena. Compared to steady-state systems, dynamical systems have many unique topological properties, such as those protected by symmetries in the time dimension. However, in dynamical systems, decoherence can deteriorate the experimentally observed topological phenomena. In this presentation, I will mainly focus on topological phenomena protected by symmetries in the time dimension, and also present a dynamical decoupling scheme to suppress noise in systems under a two-tone drive so as to facilitate the observation of topological phase transition.\n\n\n\nInvited by Prof. Zheng Zhu ( https://kits.ucas.ac.cn/index.php/people/faculty/44-faculty/184-zheng-zhu )\n
