Metric Source Completions and Integrability in Celestial Gravity
Yingnan Xu, Shuangshuang Chu
We evaluate local metric-source responses of celestial Einstein scattering in Weyl--Beltrami variables. Compact physical graviton packets retain the momentum-conservation distribut…
Large- Carrollian Thermodynamics from AdS Black-Hole Phase-Space Contractions
Yingnan Xu, Shuangshuang Chu
We develop the boundary large-rank interpretation of finite Carrollian black-hole thermodynamics and its sourced stress, scalar spectral and interacting thermal observables. Correl…
Matter one-loop logarithms and homogeneous TTNC scale response of Lifshitz black branes
Yingnan Xu, Shuangshuang Chu
We compute the logarithmic one-loop matter contribution to the thermodynamics and homogeneous twistless torsional Newton--Cartan scale response of a four-dimensional Lifshitz black…
Extended Hamiltonian thermodynamics and Carroll contractions of AdS black holes
Yingnan Xu, Shuangshuang Chu
We study extended anti-de Sitter black-hole thermodynamics under correlated contractions of the time generator and Newton coupling. We relate the contraction parameter to physical…
