First Law for Nonsingular Black Holes in 2D Dilaton Gravity
Peng Yu, Yuan Zhong
A central issue in the thermodynamics of nonsingular black holes is the apparent violation of the first law. In this work, we use 2D dilaton gravity as a simple theoretical setting…
Kink solutions in generalized 2D dilaton gravity
Yuan Zhong, Heng Guo, Yu-Xiao Liu
We study static kink solutions in a generalized two-dimensional dilaton gravity model, where the kinetic term of the dilaton is generalized to be an arbitrary function of the canon…
Thermal Corrections to Rényi Entropy in BMS Field Theory
Yuan Zhong
In the study of three-dimensional flat holography, the BMS field theory manifests the infinite-dimensional BMS symmetry, a powerful tool in elucidating numerous universal pheno…
Singular Pöschl-Teller II potentials and gravitating kinks
Yuan Zhong
We report a two-dimensional (2D) gravitating kink model, for which both the background field equations and the linear perturbation equation are exactly solvable. The background sol…
Scalar perturbation of gravitating double-kink solutions
Jun Feng, Yuan Zhong
In this letter, a two-dimensional (2D) gravity-scalar model is studied. This model supports interesting double-kink solutions, and the corresponding metric solutions can be derived…
Normal modes for two-dimensional gravitating kinks
Yuan Zhong
We study small perturbations around an arbitrary static kink solution of a two-dimensional (2D) gravity-scalar system, where the gravity part is described by a subclass of 2D dilat…
