Gravitational and electromagnetic memory
Pujian Mao, Wen-Di Tan
We present a unified investigation of memory effect in Einstein-Maxwell theory. We specify two types of memory effect, a velocity kick and a position displacement, by examining the…
BMS current algebra in the context of the Newman-Penrose formalism
Glenn Barnich, Pujian Mao, Romain Ruzziconi
Starting from an action principle adapted to the Newman-Penrose formalism, we provide a self-contained derivation of BMS current algebra, which includes the generalization of the B…
Asymptotic Structure of Einstein-Maxwell-Dilaton Theory and Its Five Dimensional Origin
H. Lü, Pujian Mao, Jun-Bao Wu
We consider Einstein-Maxwell-dilaton theory in four dimensions including the Kaluza-Klein theory and obtain the general asymptotic solutions in Bondi gauge. We find that there are…
Asymptotics with a cosmological constant: The solution space
Pujian Mao
In this work, the solution space in the Newman-Penrose formalism with a cosmological constant is derived. The residual gauge transformation preserving the solution space is also wo…
