Raman scattering of phonon polaritons under nanoscale confinement: the role of structure and environment
George Zograf, Betul Kucukoz, Oleg Kotov +10
Strong light-matter coupling gives rise to polaritons -- quasiparticles that combine both photonic and material characteristics. Here, we show that polar nanocrystals exhibit struc…
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…
Metastable Transitions and -Convergent Eyring-Kramers Asymptotics in Landau-QCD Gradient Systems
Jingxu Wu, Jie Shi
We develop a rigorous analytical framework for metastable stochastic transitions in Landau-type gradient systems inspired by QCD phenomenology. The functional $F(σ;u)=\int_Ω[\fracκ…
Z(3) Metastable Bubbles and Chiral Dynamics Across a Dark-QCD Deconfinement Transition
Jingxu Wu, Chenjia Li, Jie Shi
We present a self-contained theoretical analysis of a dark-QCD chiral transition in which the Polyakov-loop sector retains an explicit structure and couples consistently to…
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…
