Degenerate Limits of Scalar-Tensor Gravity
Bekir BaytaÅ, Xiao-Kan Guo
The paper analyzes how scalar‑tensor gravity behaves when the spatial triad becomes degenerate, using a Hamiltonian connection‑dynamics approach to derive the resulting constraints…

Gravitational helicity in connection variables
Xiao-Kan Guo, Shupeng Song
We study the gravitational helicity using the covariant phase space method. Starting from the covariant phase space of general relativity expressed in terms of connection variables…

Quantum Effective Dynamics of Papapetrou Spacetime
Xiaokan Guo, Faqiang Yuan
In this paper, we investigate the quantum effective dynamics of Papapetrou spacetime by using methods from loop quantum gravity. The Papapetrou spacetime is an extension of the Sch…
