Convexity criterion and radial-profile response for off-shell Kerr geometries: a fuzzy-dark-matter profile as an analytic benchmark
Jingxu Wu, Jie Shi, Liangyu Luo
We establish a sufficient one-minimum criterion for the off-shell Kerr family with a positive, nondecreasing mass profile , showing that $1 - 2m'…
EMRI Dephasing from a Torsion-Inspired Near-Zone Kerr Deformation: Motivated by Spin-Polarized Dark Matter
Jingxu Wu, Liangyu Luo, Daniil Stepanenko +1
Extreme-mass-ratio inspirals (EMRIs) are sensitive probes of weak conservative perturbations in the strong-field region of massive black holes. We study a phenomenological EMRI mod…
Analytical derivation of long-term dephasing caused by phase transitions in the context of Kerr black holes
Jingxu Wu, Liangyu Luo, Jie Shi
Extreme Mass Ratio Inspirals (EMRIs) constitute a prime target for future space-based gravitational-wave observatories such as LISA. In this paper, we analytically investigate the…
From Thermodynamic Criticality to Geometric Criticality: A Linear Kernel Map from Matter Susceptibilities to Black-Hole Shadows
Jingxu Wu, Jie Shi, Chenjia Li +1
We construct an explicit linear map from compact, conserved thermodynamic/effective-medium perturbations of the stress-energy tensor to the metric response in static, spherically s…
Self-Consistent Theoretical Framework for Third-Order Nonlinear Susceptibility in CdSe/ZnS--MOF Quantum Dot Composites
Jingxu Wu, Yifan Yang, Jie Shi +3
This work presents a fully theoretical and self consistent framework for calculating the third-order nonlinear susceptibility of CdSe/ZnS--MOF composite quantum dots. The approach…
Joint Simulation Study of Chiral Symmetry Recovery and Transport Response in QCD at Finite Temperature and Chemical Potentials
Jingxu Wu, Yuwei Yin, Jianing Shi
We investigate QCD matter using the two-flavor PNJL model and find that the shear viscosity to entropy density ratio η/s reaches a minimum while the bulk viscosity ζ/s peaks near…
