Covariant Hamiltonian boundary term: Reference and quasi-local quantities
Gang Sun, Chiang-Mei Chen, Jian-Liang Liu +1
The Hamiltonian for dynamic geometry generates the evolution of a spatial region along a vector field. It includes a boundary term which determines both the value of the Hamiltonia…
The cosmology in f(R,T) gravity without dark energy
Gang Sun, Yong-Chang Huang
We examine the evolution of universe in gravity where is the Ricci curvature and is the trace of energy momentum tensor. We focus on the specific form $f(R,T) = R+…
A Reference for the Gravitational Hamiltonian Boundary Term
Chiang-Mei Chen, Jian-Liang Liu, James M. Nester +1
The Hamiltonian for physical systems and dynamic geometry generates the evolution of a spatial region along a vector field. It includes a boundary term which not only determines th…
An Optimal Choice of Reference for the Quasi-Local Gravitational Energy and Angular Momentum
Gang Sun, Chiang-Mei Chen, Jian-Liang Liu +1
The boundary term of the gravitational Hamiltonian can be used to give the values of the quasi-local quantities as long as one can provide a suitable evolution vector field and an…
