Deparametrization and quantization of scalar-tensor gravity and its cosmological model
Faqiang Yuan, Haida Li, Shengzhi Li +1
The degree of freedom of the scalar field in scalar-tensor gravity is employed as "time" to deparametrize the Hamiltonian constraint of the theory. The deparametrized system is the…

Properties of 4D spinfoam quantum geometry: Results from next-to-leading order spinfoam large- asymptotics of 1-5 Pachner move
Haida Li, Muxin Han, Hongguang Liu +2
This paper proposes several criteria to probe the non-trivialities of 4-dimensional geometry that impact spinfoam amplitude. These criteria include the standard deviation of 4-volu…
