From Critical Zero Modes to Interior Dynamics in Holographic Superconductors
Yan Liu, Hong-Da Lyu
We study how the critical behavior of holographic superconductors controls the interior geometry of charged black holes. Although the exterior condensate vanishes at criticality, t…
Zero modes and oscillatory instabilities of a Lorentz-violating Kalb-Ramond field on a Schwarzschild background
Hong-Da Lyu, Zhi Xiao, Zhong-Xi Yu +1
We study equilibrium configurations and linear perturbations of a Lorentz-violating Kalb--Ramond field with a quartic symmetry-breaking potential and a non-minimal Riemann coupling…
Critical Kasner scaling from Cauchy-horizon collapse near holographic phase transitions
Ling-Long Gao, Yan Liu, Hong-Da Lyu
We study continuous scalar-hair bifurcations from stationary black holes with a nonextremal Cauchy horizon. Although the exterior deformation vanishes at criticality, the critical…
Critical and multicritical Kasner scaling in holographic phase transitions
Ling-Long Gao, Yan Liu, Hong-Da Lyu
We study how holographic phase transitions imprint their scaling laws on the local Kasner geometry inside Einstein-scalar black holes. At fixed double-trace coupling, we derive the…
Geodesics and shadows of the spindle-deformed Kerr black hole
Hong-Da Lyu, Mingzhi Wang, Shoulong Li
Recently, a new exact Ricci-flat rotating black-hole solution was constructed in four-dimensional general relativity, in which an additional parameter characterizes a spindle d…
Solar-System Bounds on Ricci-flat Spindle Deformations of Schwarzschild
Zhong-Xi Yu, Hong-Da Lyu, Shoulong Li
Recently, a new class of deformed black-hole exact solutions was constructed in four-dimensional general relativity. The deformation is controlled by a parameter , which survive…
Black holes and neutron stars in massive Hellings-Nordtvedt theory
Zhe Luo, Liang Liang, Zhong-Xi Yu +3
Hellings-Nordtvedt theory is a vector-tensor theory in which a vector field is nonminimally coupled to curvature through two independent interactions and $A^μA^…
