It has long been conjectured that the large deconfinement phase transition of super-Yang-Mills corresponds via AdS/CFT to the Hawking-Page transit…
Scattering From -Strings in

Motivated by understanding the scattering of gravitons and their superpartners from extended -strings in type IIB string theory via AdS/CFT, we study an integrated two-poin…
Casimir Energy and Modularity in Higher-dimensional Conformal Field Theories
Conghuan Luo, Yifan Wang
An important problem in Quantum Field Theory (QFT) is to understand the structures of observables on spacetime manifolds of nontrivial topology. Such observables arise naturally wh…
Low-temperature plasma simulation based on physics-informed neural networks: frameworks and preliminary applications
Linlin Zhong, Bingyu Wu, Yifan Wang
Plasma simulation is an important and sometimes only approach to investigating plasma behavior. In this work, we propose two general AI-driven frameworks for low-temperature plasma…
