Scalar wave scattering by black holes embedded in dark matter halos
Shi-Qian Hu, Federico Piazza
We study the scattering of massless scalar waves by static black holes embedded in dark matter halos. The halo is modelled by means of a Hernquist profile, for which the Einstein e…
Testing Higher Derivative Gravity Through Tunnelling
Ruth Gregory, Shi-Qian Hu
Higher derivative terms in the gravitational action are natural from the perspective of quantum gravity, but are perceived as leading to a lack of well-posedness. The Gauss Bonnet…
Primordial Black Holes Are True Vacuum Nurseries
Louis Hamaide, Lucien Heurtier, Shi-Qian Hu +1
The Hawking evaporation of primordial black holes (PBH) reheats the Universe locally, forming hot spots that survive throughout their lifetime. We propose to use the temperature pr…
Seeded vacuum decay with Gauss-Bonnet
Ruth Gregory, Shi-Qian Hu
We investigate false vacuum decay catalysed by black holes under the influence of the higher order Gauss-Bonnet term. We study both bubble nucleation and Hawking-Moss types of phas…
Hadronic weak decays of the charmed baryon
Shiyong Hu, Guanbao Meng, Fanrong Xu
Two-body hadronic weak decays of the charmed baryon , including Cabibbo-favored (CF), singly Cabibbo-suppressed (SCS) and doubly Cabibbo-suppressed (DCS) modes, are studied sy…
Revisiting black hole thermodynamics in massive gravity: charged particle absorption and shell of dust falling
Shi-Qian Hu, Bo Liu, Xiao-Mei Kuang +1
We study the variation of the massive black hole in both normal and extended thermodynamic phase spaces via two methods. The first method includes a charged particle absorbed by th…
Expansion of tree amplitudes for EM and other theories
Shi-Qian Hu, Kang Zhou
The expansions of tree-level amplitudes for one theory into amplitudes for another theory, which have been studied in various recent literatures, exhibit hidden connections between…
No Violation of the Second Law in Extended Black Hole Thermodynamics
Shi-Qian Hu, Yen Chin Ong, Don N. Page
Recently a number of papers have claimed that the horizon area - and thus the entropy - of near extremal black holes in anti-de Sitter spacetimes can be reduced by dropping particl…
Probing Sterile Neutrino via Lepton Flavor Violating Decays of Mesons
Shiyong Hu, Sam Ming-Yin Wong, Fanrong Xu
A sterile neutrino at GeV mass scale is of particular interest in this work. Though not take part in neutrino oscillation, the sterile neutrino can induce flavor violating semilept…
A Note on Smarr Relation and Coupling Constants
Shi-Qian Hu, Xiao-Mei Kuang, Yen Chin Ong
The Smarr relation plays an important role in black hole thermodynamics. It is often claimed that the Smarr relation can be written down simply by observing the scaling behavior of…
Joule-Thomson expansion in AdS black holes with momentum relaxation
Adolfo Cisterna, Shi-Qian Hu, Xiao-Mei Kuang
The inner structure of realistic materials make them exhibit momentum relaxation. In this paper we study the holographic version of the Joule-Thomson effect on AdS black holes in w…
Holographic heat engine in Horndeski model with the -essence sector
Shi-Qian Hu, Xiao-Mei Kuang
We study the extended thermodynamical properties of the charged black hole in Horndeski model with the -essence sector. Then we define a holographic heat engine via the black ho…
