Spinfoam on Lefschetz Thimble: Markov Chain Monte-Carlo Computation of Lorentzian Spinfoam Propagator
Muxin Han, Zichang Huang, Hongguang Liu +2
We compute numerically the Lorentzian Engle-Pereira-Rovelli-Livine (EPRL) spinfoam propagator on a 4-simplex, by adapting the methods of Lefschetz thimble and Markov Chain Monte-Ca…

Semiclassical Limit of New Path Integral Formulation from Reduced Phase Space Loop Quantum Gravity
Muxin Han, Hongguang Liu
Recently, a new path integral formulation of Loop Quantum Gravity (LQG) has been derived in arXiv:1910.03763 from the reduced phase space formulation of the canonical LQG. This pap…
