Real Part Emergence in Purely Imaginary Quasinormal Modes in Perturbed de Sitter Braneworlds
Hai-Long Jia, Wen-Di Guo, Yun-Tao Gu +1
For braneworlds with infinite extra dimensions, an analysis of the stability of the characteristic spectrum is essential for understanding their dynamical properties. In this study…

Spontaneous Symmetry Breaking and the Emergent Einstein-Standard Model: From Weyl x SU (2)L x U (1)Y Gauge Theory to Geometric Mass Generation
Hao-Qian Peng, Yun-Tao Gu, Yu-Xiao Liu
We construct a Weyl x SU(2)_L x U(1)_Y invariant theory by extending four-dimensional Weyl quadratic gravity with Weyl-invariant scalar, fermion, Yukawa and gauge sectors. The quad…

Quasinormal modes of an electrically charged Kalb-Ramond black hole
Yun-Tao Gu, Wen-Di Guo, Yu-Xiao Liu
Lorentz violation serves as a significant feature in many modified theories of gravity. In particular, spontaneous Lorentz violation induced by the Kalb-Ramond field has attracted…
