Exact characterizations for quantum conditional mutual information and some other entropies
Zhou Gang
Lieb and Ruskai's strong subadditivity theorem, which shows that the conditional mutual information must be nonnegative, is fundamental in quantum theory. It has numerous applicati…

On the continuity of phase transition of three-dimensional square-lattice XY models
Zhou Gang
We study the continuity of magnetization at the phase transition of the ferromagnetic XY model in the three-dimensional square lattice with the nearest neighborhood interaction. We…

Precise asymptotics near a generic singularity of mean curvature flow
Zhou Gang, Shengwen Wang
In the present paper we study a type of generic singularity of mean curvature flow modelled on the bubble-sheet , and we derive an asymptotic profile…
