FUNDAMENTAL STRUCTURE OF LOOP QUANTUM GRAVITY
- Muxin Han, Weiming Huang, Yongge Ma
- Physics
- 16 September 2005
In the recent twenty years, loop quantum gravity, a background independent approach to unify general relativity and quantum mechanics, has been widely investigated. The aim of loop quantum gravity is…
Asymptotics of Spinfoam Amplitude on Simplicial Manifold: Lorentzian Theory
The present paper studies the large-j asymptotics of the Lorentzian EPRL spinfoam amplitude on a 4d simplicial complex with an arbitrary number of simplices. The asymptotics of the spinfoam amplitude…
Five-dimensional Brans-Dicke theory and cosmic acceleration
- Li-e Qiang, Yongge Ma, Muxin Han, Dan Yu
- Physics, Mathematics
- 14 November 2004
We consider a 5-dimensional scalar-tensor theory which is a direct generalization of the original 4-dimensional Brans-Dicke theory to five dimensions. By assuming that there is a…
SL(2,C) Chern–Simons theory, a non-planar graph operator, and 4D quantum gravity with a cosmological constant: Semiclassical geometry

4-dimensional Spin-foam Model with Quantum Lorentz Group
- Muxin Han
- Physics
- 19 December 2010
We study the quantum group deformation of the Lorentzian EPRL spin-foam model. The construction uses the harmonic analysis on the quantum Lorentz group. We show that the quantum group spin-foam model…
On Spinfoam Models in Large Spin Regime
- Muxin Han
- Physics
- 20 April 2013
We study the semiclassical behavior of Lorentzian Engle–Pereira–Rovelli–Livine (EPRL) spinfoam model, by taking into account the sum over spins in the large spin regime. We also employ the method of…
Semiclassical analysis of spinfoam model with a small Barbero-Immirzi parameter
- Muxin Han
- Physics
- 20 April 2013
We study the semiclassical behavior of Lorentzian Engle-Pereira-Rovelli-Livine (EPRL) spinfoam model, by taking into account of the sum over spins in the large spin regime. The large spin parameter…
Effective dynamics from coherent state path integral of full loop quantum gravity
- Muxin Han, Hongguang Liu
- PhysicsPhysical Review D
- 9 October 2019
A new routine is proposed to relate loop quantum cosmology (LQC) to loop quantum gravity (LQG) from the perspective of effective dynamics. We derive the big-bang singularity resolution and big bounce…
Encoding Curved Tetrahedra in Face Holonomies: Phase Space of Shapes from Group-Valued Moment Maps
- Hal M Haggard, Muxin Han, A. Riello
- Mathematics
- 9 June 2015
We present a generalization of Minkowski’s classic theorem on the reconstruction of tetrahedra from algebraic data to homogeneously curved spaces. Euclidean notions such as the normal vector to a…
Cosmological Constant in LQG Vertex Amplitude
- Muxin Han
- Mathematics
- 11 May 2011
A new q-deformation of the Euclidean EPRL/FK vertex amplitude is proposed by using the evaluation of the Vassiliev invariant associated with a 4-simplex graph (related to two copies of quantum SU(2)…
