Perturbative study of Supercritical Crossover in Noncommutative-corrected Spacetime
Ankit Anand, Shoucheng Wang
We analytically study the Widom line and supercritical crossover of noncommutative charged AdS black holes. Treating the noncommutative parameter perturbatively, we compute the…

Null infinity as Chern-Simons theories and its quantization
Hongwei Tan, Kui Xiao, Shoucheng Wang
This paper studies the quantization of the future null infinity () of an asymptotically flat spacetime. Based on the observation by Ashtekar and Speziale that $\math…
