摘要 (Abstract): Entanglement is a ubiquitous feature of quantum physics of interacting systems. It has been believed that it does exist at high temperature due to strong thermal fluctuations. However, theoretically it has been shown that it can be sustained between two interacting parametric oscillators at high temperature. Such a phenomenon is related to parametric instability. In this talk, I will give an introduction to hot entanglement, and the role of instability, and use a few examples to show that instability is only a necessary condition to the existence of hot entanglement. Furthermore, I offer a more intuitive way to “rephrase” these examples in terms of two-mode squeezing formalism, and comment on the practical feasibility to realize hot entanglement.

After taking the postdoc at National Dong Hwa University, Taiwan, I became a research fellow at the Center for Field Theory and Particle Physics, Fudan University, and then the Visiting Associate Professor, Maryland Center of Fundamental Physics, University of Maryland. In 2019, I took the Research Fellow position at National Central University.

Dr. Hsiang’s research interest mainly focuses on nonequilibrium field theory with the applications to quantum vacuum, nonequilibrium quantum information, nonequilibrium quantum thermodynamics of the small system, and field theory in curved space.
