Dynamics of Regge calculus with torsion
Ruijue Yan, You Ding, Yongge Ma +1
The discrete geometry on an -dimensional simplicial manifold are studied, in order to incorporate torsion into Regge calculus. In each simplex, the edge vectors are assigned to…
Expansion operators in spherically symmetric loop quantum gravity
Xiaotian Fei, Gaoping Long, Yongge Ma +1
The ingoing and outgoing null expansions associated to a spatial 2-sphere are quantized in the spherically symmetric model of loop quantum gravity. It is shown that the resulting e…
Covariant effective spacetimes of spherically symmetric electrovacuum with a cosmological constant
Jinsong Yang, Cong Zhang, Yongge Ma
An algebraic framework was introduced in our previous works to address the covariance issue in spherically symmetric effective quantum gravity. This paper extends the framework to…
Black holes and covariance in effective quantum gravity: A solution without Cauchy horizons
Cong Zhang, Jerzy Lewandowski, Yongge Ma +1
The issue of general covariance in effective quantum gravity models within the Hamiltonian framework is addressed. The previously proposed equations for the covariance condition in…
Black Holes and Covariance in Effective Quantum Gravity
Cong Zhang, Jerzy Lewandowski, Yongge Ma +1
The longstanding issue of general covariance in effective models of quantum gravity is addressed, which arises when canonical quantum gravity leads to a semiclassical model describ…
Conformally Invariant Brans-Dicke Loop Quantum Cosmology: A Quantum Geometric Model of Linking Theory
Chun-Yen Lin, Xiangjing Liu, Yongge Ma +1
The loop quantization of the conformal Brans-Dicke cosmology is explored in the spatially flat and Bianchi-I setting. The scalar and conformal constraints governing the canonical m…
