Ideal gases and degenerate Fermi gases in external torsion fields
Chih-Hung Wang, Yu-Huei Wu
We investigate the effects of external torsion fields on ideal gases and Fermi gases, and derive a macroscopic quantity, which we call torsion susceptibility. We first consider the…
How can one observe gravitational angular momentum radiation from a dynamical source near null infinity?
Chih-Hung Wang, Yu-Huei Wu
To answer a question of how can one observed angular momentum radiation near null infinity, one can first transform the dynamical twisting vacuum solution and make it satisfy Bondi…
Gravitational radiation and angular momentum flux from a spinning dynamical black hole
Chih-Hung Wang, Yu-Huei Wu
A four-dimensional asymptotic expansion scheme is used to study the next order effects of the nonlinearity near a spinning dynamical black hole. The angular momentum flux and energ…
Brans-Dicke theory of gravity with torsion: A possible solution of the -problem
Yu-Huei Wu, Chih-Hung Wang
We study the Brans-Dicke theory of gravity in Riemann-Cartan space-times, and obtain general torsion solutions, which are completely determined by Brans-Dicke scalar field , in…
Local and global structure of domain wall space-times
Yu-Huei Wu, Chih-Hung Wang
We present a general proof on the equivalence of the comoving-coordinate approach, where the wall is fixed at a constant coordinate variable, and moving-wall approach, where the wa…
Quantum fluctuations in planar domain-wall space-times: A possible origin of primordial preferred direction
Chih-Hung Wang, Yu-Huei Wu, Stephen D. H. Hsu
We study the gravitational effects of a planar domain wall on quantum fluctuations of a massless scalar field during inflation. By obtaining an exact solution of the scalar field e…
