A Mathematica program for numerically computing real and complex critical points in 4-dimensional Lorentzian spinfoam amplitude

Muxin Han, Hongguang Liu, Dongxue Qu

This work develops a comprehensive algorithm and a Mathematica program to construct boundary data and compute real and complex critical points in spinfoam amplitudes. Our approach…

Spin foam amplitude of the black-to-white hole transition

Muxin Han, Dongxue Qu, Cong Zhang

It has been conjectured that quantum gravity effects may cause the black-to-white hole transition due to quantum tunneling. The transition amplitude of this process is explored wit…

Deficit Angles in 4D Spinfoam with Cosmological Constant: (Anti) de Sitter-ness and More

Muxin Han, Qiaoyin Pan

This paper investigates the critical behaviors of the 4-dimensional spinfoam model with cosmological constant for a general 4-dimensional simplicial complex as the discretization o…

Cosmological Dynamics from Covariant Loop Quantum Gravity with Scalar Matter

Muxin Han, Hongguang Liu, Dongxue Qu +2

We study homogenous and isotropic quantum cosmology using the spinfoam formalism of Loop Quantum Gravity (LQG). We define a coupling of a scalar field to the 4-dimensional Lorentzi…

Quantum Group Intertwiner Space From Quantum Curved Tetrahedron

Muxin Han, Chen-Hung Hsiao, Qiaoyin Pan

In this paper, we develop a quantum theory of homogeneously curved tetrahedron geometry, by applying the combinatorial quantization to the phase space of tetrahedron shapes defined…
