Quasilocal conservation laws in cosmology: a first look
Marius Oltean, Hossein Bazrafshan Moghaddam, Richard J. Epp
Quasilocal definitions of stress-energy-momentum---that is, in the form of boundary densities (in lieu of local volume densities)---have proven generally very useful in formulating…
Energy of cosmological spacetimes and perturbations: a quasilocal approach
Marius Oltean, Hossein Bazrafshan Moghaddam, Richard J. Epp
Quasilocal definitions of stress-energy-momentum -- that is, in the form of boundary densities (rather than local volume densities) -- have proven generally very useful in formulat…
Motion of localized sources in general relativity: gravitational self-force from quasilocal conservation laws
Marius Oltean, Richard J. Epp, Carlos F. Sopuerta +2
An idealized "test" object in general relativity moves along a geodesic. However, if the object has a finite mass, this will create additional curvature in the spacetime, causing i…
Relativistic geoids and time dependence: quasilocal frames versus isochronometric surfaces
Marius Oltean, Richard J. Epp, Paul L. McGrath +1
In a recent paper [D. Philipp, V. Perlick, D. Puetzfeld, E. Hackmann, and C. Lämmerzahl, Phys. Rev. D 95, 104037 (2017)], a definition of a general-relativistic geoid, restricted t…
Geoids in General Relativity: Geoid Quasilocal Frames
Marius Oltean, Richard J. Epp, Paul L. McGrath +1
We develop, in the context of general relativity, the notion of a geoid -- a surface of constant "gravitational potential". In particular, we show how this idea naturally emerges a…
Post-Newtonian Conservation Laws in Rigid Quasilocal Frames
Paul L. McGrath, Melanie Chanona, Richard J. Epp +2
In recent work we constructed completely general conservation laws for energy and linear and angular momentum of extended systems in general relativity based on the notion of a rig…
