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^…

Revisiting black holes and their thermodynamics in Einstein-Kalb-Ramond gravity

Zhong-Xi Yu, Hong-Da Lyu, Mandula Huhe +1

Einstein-Kalb-Ramond (EKR) gravity is an alternative theory in which a rank-two antisymmetric tensor field, the Kalb-Ramond field, is nonminimally coupled to gravity, potentially g…

On AdS/ICFT with a dynamical scalar field located on the brane

Yan Liu, Hong-Da Lyu, Chuan-Yi Wang

We exploit holographic duality to study the system of a one-dimensional interface contacting two semi-infinite two-dimensional CFTs. Central to our investigation is the introductio…

Internal structure of hairy rotating black holes in three dimensions

Ling-Long Gao, Yan Liu, Hong-Da Lyu

We construct hairy rotating black hole solutions in three dimensional Einstein gravity coupled to a complex scalar field. When we turn on a real and uniform source on the dual CFT,…

Black hole interiors in holographic topological semimetals

Ling-Long Gao, Yan Liu, Hong-Da Lyu

We study the black hole interiors in holographic Weyl semimetals and holographic nodal line semimetals. We find that the black hole singularities are of Kasner form. In the topolog…

Properties of gapped systems in AdS/BCFT

Yan Liu, Hong-Da Lyu, Jun-Kun Zhao

We study the conductivities and entanglement structures of two different holographic gapped systems at zero density in the presence of boundaries within AdS/BCFT. The first gapped…

Black hole singularities across phase transitions

Yan Liu, Hong-Da Lyu, Avinash Raju

We study the behavior of black hole singularities across the Hawking-Page phase transitions, uncovering possible connections between the physics inside and outside the horizon. We…

On the Size of a Black Hole: The Schwarzschild is the Biggest

H. Lu, Hong-Da Lyu

We consider static black holes in Einstein gravity and study parameters characterizing the black hole size, namely the radii of the horizon , photon sphere and bl…

Criticality in Gauged Supergravities

Shou-Long Li, Hong-Da Lyu, Hua-Kai Deng +1

AdS black holes show richer transition behaviors in extended phase space by assuming the cosmological constant and its conjugate quantity to behave like thermodynamic pressure and…

J. Wei, B. Cordier, S. Antier +77

To take advantage of the astrophysical potential of Gamma-Ray Bursts (GRBs), Chinese and French astrophysicists have engaged the SVOM mission (Space-based multi-band astronomical V…
