Generation of gravitating solutions with Baryonic charge from Einstein-Scalar-Maxwell seeds
Fabrizio Canfora, Anibal Neira, Seung Hun Oh
We establish, for the first time, an exact correspondence between Einstein-scalar-Maxwell theory and gauged Skyrme-Maxwell-Einstein models in (3+1) dimensions. By constructing the…
Poisson algebra of quasilocal angular momentum and its asymptotic limit
Jong Hyuk Yoon, Seung Hun Oh
We study the previously proposed quasilocal angular momentum of gravitational fields in the absence of isometries. The quasilocal angular momentum has the following attracti…
Second-order energy-momentum tensor of a scalar field
Inyong Cho, Jinn-Ouk Gong, Seung Hun Oh
We investigate the second-order effective energy-momentum tensor (2EMT) constructed by the quadratic terms of the linear scalar cosmological perturbations while the universe is dom…
Second-order effective energy-momentum tensor of gravitational scalar perturbations with perfect fluid
Inyong Cho, Jinn-Ouk Gong, Seung Hun Oh
We investigate the second-order gravitational scalar perturbations for a barotropic fluid. We derive the effective energy-momentum tensor described by the quadratic terms of the gr…
Solution-generating methods of Einstein's equations by Hamiltonian reduction
Seung Hun Oh, Kyoungtae Kimm, Yongmin Cho +1
The purpose of this paper is to demonstrate a new method of generating exact solutions to the Einstein's equations obtained by the Hamiltonian reduction. The key element to the suc…
