Analytical Study for Primordial Non-Gaussianity in the gravity 4D Einstein-scalar-Gauss-Bonnet Inflation
A. Agung, U. Sambiri, G. Hikmawan +1
An inflationary model can be constrained by non-gaussian statistics as a parameter in the LSS (Large Scale Structure) distribution, and in the radiation of CMB (Cosmic Microwave Ba…

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…

Near-extremal Kerr-like ECO in the Kerr/CFT Correspondence in Higher Spin Perturbations
M. Zhahir Djogama, Muhammad F. A. R. Sakti, Freddy P. Zen +1
The Kerr/CFT correspondence has been established to explore the quantum theory of gravity in the near-horizon geometry of a extreme Kerr black holes. The quantum gravitational corr…
