Fermion coupling to loop quantum gravity: canonical formulation
Jerzy Lewandowski, Cong Zhang
In the model of a fermion field coupled to loop quantum gravity, we consider the Gauss and the Hamiltonian constraints. According to the explicit solutions to the Gauss constraint,…
Twisted geometry coherent states in all dimensional loop quantum gravity: I. Construction and Peakedness properties
Gaoping Long, Xiangdong Zhang, Cong Zhang
A new family of coherent states for all dimensional loop quantum gravity are proposed, which is based on the generalized twisted geometry parametrization of the phase space of $SO(…
Polarization measurement for the dileptonic channel of scattering using generative adversarial network
Jinmian Li, Cong Zhang, Rao Zhang
Measuring the polarization fractions of the scattering reveals the interactions of the Higgs boson as well as new neutral states that are related to the standard model ele…
Loop quantum deparametrized Schwarzschild interior and discrete black hole mass
Cong Zhang, Yongge Ma, Shupeng Song +1
We present the detailed analyses of a model of loop quantum Schwarzschild interior coupled to a massless scalar field and extend the results in our previous rapid communication arX…
Reduced Phase Space Quantization of Black Holes: Path Integrals, and Effective Dynamics
Cong Zhang
We consider the loop quantum theory of the spherically symmetric model of gravity coupled to Gaussian dust fields, where the Gaussian dust fields provide a material reference frame…
Superposition type coherent states in all dimensional loop quantum gravity
Gaoping Long, Cong Zhang, Xiangdong Zhang
We propose a new kind of coherent state for the general formulation of loop quantum gravity in the -dimensional space-time. Instead of Thiemann's coherent state fo…
Multi-scalar signature of self-interacting dark matter in the NMSSM and beyond
Jinmian Li, Junle Pei, Cong Zhang
This work studies the self-interacting dark matter (SIDM) scenario in the general NMSSM and beyond, where the dark matter is a Majorana fermion and the force mediator is a scalar b…
Relating spin-foam to canonical loop quantum gravity by graphical calculus
Jinsong Yang, Cong Zhang, Yongge Ma
The graphical calculus method is generalized to study the relation between covariant and canonical dynamics of loop quantum gravity. On one hand, a graphical derivation of the part…
First-Order Quantum Correction in Coherent State Expectation Value of Loop-Quantum-Gravity Hamiltonian
Cong Zhang, Shicong Song, Muxin Han
Given the non-graph-changing Hamiltonian in Loop Quantum Gravity (LQG), , the coherent state expectation value of , a…
