Shear quasinormal modes of Gauss-Bonnet black brane: the first post-hydrodynamic order
Towe Wang
Assuming in the low-frequency limit, we apply the refined recipe to compute the dispersion relation of shear quasinormal modes of the Gauss-Bonnet black br…
Notes on diffusive and shear quasinormal modes of black branes
Yu-Chen Ding, Li Li, Towe Wang
In the literature, to extract the dispersion relation of low-frequency quasinormal modes in both diffusive and shear channels, it is a customary recipe to assume firstly $ω\sim\mat…
Action growth rates of black holes in the Chern-Simons modified gravity
Yu-Chen Ding, Towe Wang
Among many modified gravity theories, the Chern-Simons modified gravity stands out as one of the few examples whose Dirichlet boundary problem has been well studied. Known solution…
Modified entropic gravity revisited
Tower Wang
Inspired by Verlinde's idea, some modified versions of entropic gravity have appeared in the literature. Extending them in a unified formalism, we derive the generalized gravitatio…
A quantum oscillator model for entropic gravity
Towe Wang, Yi-Wei Wu, Jian Zhao
In Verlinde's theory of entropic gravity, the internal degrees of freedom are marked by "bits", but the microscopic origin of "bits" is unknown hitherto. To this direction, we adop…
Coulomb Force as an Entropic Force
Tower Wang
Motivated by Verlinde's theory of entropic gravity, we give a tentative explanation to Coulomb's law with an entropic force. When trying to do this, we find the equipartition rule…
Cosmic Steps in Modeling Dark Energy
Tower Wang
The past and recent data analyses gave some hints of steps in dark energy. Considering the dark energy as a dynamical scalar field, we investigate several models with various steps…
Curvature and Entropy Perturbations in Generalized Gravity
Xiangdong Ji, Tower Wang
We investigate the cosmological perturbations in generalized gravity, where the Ricci scalar and a scalar field are non-minimally coupled via an arbitrary function. In the Friedman…
From N M2's to N D2's
Yi Pang, Tower Wang
In this short note, we reduce the N=6, U(N)xU(N) Chern-Simons gauge theories to N=8, U(N) Yang-Mills gauge theories. This process corresponds to recovering the world-volume theory…
M2-branes Coupled to Antisymmetric Fluxes
Miao Li, Tower Wang
By turning on antisymmetric background fluxes, we study how multiple M2-branes are coupled to them. Our investigation concentrates on the gauge invariance conditions for the Myers-…
Probing Alpha-Vacua of Black Holes in LHC
Tower Wang
Motivated by the idea of alpha-vacua in Schwarzschild spacetime, we studied the deformed spectrum of Hawking radiation. Such a deformation would leave signatures on the small black…
A Weak Gravity Conjecture for Scalar Field Theories
Miao Li, Wei Song, Yushu Song +1
We show that the recently proposed weak gravity conjecture\cite{AMNV0601} can be extended to a class of scalar field theories. Taking gravity into account, we find an upper bound o…
Some Low Dimensional Evidence for the Weak Gravity Conjecture
Miao Li, Wei Song, Tower Wang
We discuss a few examples in 2+1 dimensions and 1+1 dimensions supporting a recent conjecture concerning the relation between the Planck scale and the coupling strength of a non-gr…
