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…
Representations of a quantum-deformed Lorentz algebra, Clebsch-Gordan map, and Fenchel-Nielsen representation of complex Chern-Simons theory at level-
Muxin Han
A family of infinite-dimensional irreducible -representations on is defined for a quantum-deformed Lorentz algebra $\maths…
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…
