Gravitational partition function under volume constraints
Shan-Ping Wu, Peng Cheng, Shao-Wen Wei
The Euclidean action provides a bridge between gravitational thermodynamics and the partition function. In this work, we further investigate the gravitational partition function un…

Integral cubic form of 5D minimal supergravities and non-perturbative anomalies in 6D (1,0) theories
Peng Cheng, Michael N. Milam, Ruben Minasian
A five-dimensional minimal supergravity theory coupled to vector and hypermultiplets is specified by a set of trilinear couplings, given by an intersection form , and grav…

Scattering Radiation Emitted Near a Black Hole Horizon
Peng Cheng
We study a family of outgoing electromagnetic radiation states prepared outside but arbitrarily close to the horizon of a Schwarzschild black hole, with frequencies that remain uni…
