Quasi-Local Energy Flux of Spacetime Perturbation
Roh-Suan Tung, Hoi-Lai Yu
A general expression for quasi-local energy flux for spacetime perturbation is derived from covariant Hamiltonian formulation using functional differentiability and symplectic stru…
Stationary untrapped boundary conditions in general relativity
Roh-Suan Tung
A class of boundary conditions for canonical general relativity are proposed and studied at the quasi-local level. It is shown that for untrapped or marginal surfaces, fixing the a…
Origin of the Immirzi Parameter
Chung-Hsien Chou, Roh-Suan Tung, Hoi-Lai Yu
Using quadratic spinor techniques we demonstrate that the Immirzi parameter can be expressed as ratio between scalar and pseudo-scalar contributions in the theory and can be interp…
Spinor Formulations for Gravitational Energy-Momentum
Chiang-Mei Chen, James M. Nester, Roh-Suan Tung
We first describe a class of spinor-curvature identities (SCI) which have gravitational applications. Then we sketch the topic of gravitational energy-momentum, its connection with…
Gravity and the Quantum Vacuum Inertia Hypothesis. I. Formalized Groundwork for Extension to Gravity
Alfonso Rueda, Bernard Haisch, Roh Tung
It has been shown [1,2] that the electromagnetic quantum vacuum makes a contribution to the inertial mass, , in the sense that at least part of the inertial force of oppositio…
Gravitational Energy-Momentum in the Tetrad and Quadratic Spinor Representations of General Relativity
Roh S. Tung, James M. Nester
In the Tetrad Representation of General Relativity, the energy-momentum expression, found by Moller in 1961, is a tensor wrt coordinate transformations but is not a tensor wrt loca…
