First-Order Quantum Correction in Coherent State Expectation Value of Loop-Quantum-Gravity Hamiltonian: Overview and Results
Cong Zhang, Shicong Song, Muxin Han
Given the Loop-Quantum-Gravity (LQG) non-graph-changing Hamiltonian , the coherent state expectation value admits an semiclassical ex…
Loop quantum cosmology from an alternative Hamiltonian. II. Including the Lorentzian term
Jinsong Yang, Cong Zhang, Yongge Ma
The scheme of using the Chern-Simons action to regularize the gravitational Hamiltonian constraint is extended to including the Lorentzian term in the cosmological model. The…
Koopman Operator and Phase Space Partition of Chaotic Maps
Cong Zhang, Yueheng Lan
Koopman operator describes evolution of observables in the phase space, which could be used to extract characteristic dynamical features of a nonlinear system. Here, we show that i…
Loop quantum Schwarzschild interior and black hole remnant
Cong Zhang, Yongge Ma, Shupeng Song +1
The interior of Schwarzschild black hole is quantized by the method of loop quantum gravity. The Hamiltonian constraint is solved and the physical Hilbert space is obtained in the…
Alternative dynamics in loop quantum Brans-Dicke cosmology
Shupeng Song, Cong Zhang, Yongge Ma
To inherit more features of full loop quantum Brans-Dicke theory, the Euclidean and Lorentzian terms of the Hamiltonian constraint are quantized independently in loop quantum Brans…
Entropy of black holes with arbitrary shapes in loop quantum gravity
Shupeng Song, Haida Li, Yongge Ma +1
The quasi-local notion of an isolated horizon is employed to study the entropy of black holes without any particular symmetry in loop quantum gravity. The idea of characterizing th…
