Rotating neutron stars with chaotic magnetic fields in general relativity and Rastall gravity
M. Lawrence Pattersons, Freddy P. Zen, Hadyan L. Prihadi +2
Observations indicate that the magnetic fields on neutron stars (NSs) lie in the range of - G. We investigate rotating NSs with chaotic magnetic fields in both gen…
Decoherence Induced by the Noise of Primordial Graviton with Minimum Uncertainty Initial States
Anom Trenggana, Freddy P. Zen, Getbogi Hikmawan
We have investigated the decoherence induced by the primordial graviton, using the influence functional method, to show whether this method is still effective in detecting graviton…
Dynamics of Charged and Rotating NUT Black Holes in Rastall Gravity
Hadyan L. Prihadi, Muhammad F. A. R. Sakti, Getbogi Hikmawan +1
In this work, we generalized the Kerr-Newman-NUT black hole solution in Rastall gravity from Ref. 1. Here we are more focused on the black hole dynamics such as the event horizons,…
No-Go Theorem for Gauss-Bonnet Inflation without Inflaton Potential
Getbogi Hikmawan, Jiro Soda, Agus Suroso +1
Recently, an interesting inflationary scenario, named Gauss-Bonnet inflation, is proposed by Kanti et al.~\cite{Kanti:2015pda,Kanti:2015dra}. In the model, there is no inflaton pot…
