The integrable Bullough-Dodd model under celestial holography
Minjia Wang, Wei Fan
We study celestial amplitudes for the S-matrix of the 2d integrable Bullough-Dodd model. This model has bound states that appear as poles in the physics strip of its 2d S-matrix, w…

Geodesic Motion of Test Particles around the Scalar Hairy Black Holes with Asymmetric Vacua
Hongyu Chen, Wei Fan, Xiao Yan Chew
An asymptotically flat hairy black hole (HBH) can exhibit distinct characteristics when compared to the Schwarzschild black hole, due to the evasion of no-hair theorem by minimally…
