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…
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…
Canonical loop quantization of the lowest-order projectable Horava gravity
Xiangdong Zhang, Jinsong Yang, Yongge Ma
The Hamiltonian formulation of the lowest-order projectable Horava gravity, namely the so-called - gravity, is studied. Since a preferred foliation has been chosen in project…
Consistency check on the fundamental and alternative flux operators in loop quantum gravity
Jinsong Yang, Yongge Ma
There are different constructions of the flux of triad in loop quantum gravity, namely the fundamental and alternative flux operators. In parallel to the consistency check on the t…
Light bending and gravitational lensing in Brans-Dicke theory
Xiaojun Gao, Shupeng Song, Jinsong Yang
As an important candidate theory of gravity, Brans-Dicke theory has been widely studied. In this paper, we investigate light bending and gravitational lensing by compact objects in…
Loop quantum cosmology from an alternative Hamiltonian
Jinsong Yang, Cong Zhang, Yongge Ma
In this paper, a new Hamiltonian constraint operator for loop quantum cosmology is constructed by using the Chern-Simons action. The quantum dynamics of the cosmological mode…
