Minimally modified gravity with auxiliary constraints

报告题目： Minimally modified gravity with auxiliary constraints报告人：姚志邦 博士（中山大学）报告时间：2023年05月05日（周五）下午15:30-16:30报告地点：北洋园校区49教210室报告摘要：Modified gravity without arousing new degrees of freedom (DOF) is a kind of interesting gravitational theories which propagate only two tensorial DOF (TTDOF) like what happens in GR. Modified gravity theories with su...

Aspects of Sachdev-Ye-Kitaev model

报告题目：Aspects of Sachdev-Ye-Kitaev model报告人：葛先辉 教授（上海大学）报告时间：2023年05月04日（周四）下午15:30-16:30报告地点：北洋园校区49教210室报告摘要：In this talk, we will show how to match the thermodynamics of the (0 + 1)-dimensional SYK model, with that of a (1 + 1)-dimensional gravitational model. We focus on a model of deformed JT gravity, characterized by some unknown dilaton p...

Island phase as a property of quantum state and Hilbert space

报告题目：Island phase as a property of quantum state and Hilbert space报告人：文 强 副教授（东南大学）报告时间：2023年04月27日（周四）下午15:30-16:30报告地点：北洋园校区49教210室报告摘要：In this talk I will give a purely quantum information perspective for the Island formula. More explicitly we show that, in a quantum system when the state of a subset is totally encoded in the state of anothe...
