Stationary solutions in the small- expansion of GR
Enes Bal, Ertuğrul Ekiz, Emre Onur Kahya +1
We study the small- expansion of general relativity in ADM variables up to next-to-next-to-leading order (NNLO). We show that, in the stationary sector, this formulation renders…
One loop corrected conformally coupled scalar mode equations during inflation
Sibel Boran, Emre Onur Kahya, Sohyun Park
We employ a fully renormalized computation of the one loop contribution to the self-mass-squared of the conformally coupled (CC) scalar interacting with gravitons during inflation…
Quantum gravity corrections to the conformally coupled scalar self-mass-squared on de Sitter II: kinetic-conformal cross terms
Sibel Boran, Emre Onur Kahya, Sohyun Park
The present work is the second part of a series of computations for the self-mass-squared of the conformally coupled (CC) scalar interacting with gravitons. This work includes the…
Constraints on frequency-dependent violations of Shapiro delay from GW150914
Emre O. Kahya, Shantanu Desai
On 14th September 2015, a transient gravitational wave (GW150914) was detected by the two LIGO detectors at Hanford and Livingston from the coalescence of a binary black hole syste…
Constructing an Inflaton Potential by Mimicking Modified Chaplygin Gas
E. O. Kahya, B. Pourhassan, S. Uraz
In this paper, we considered an inflationary model that effectively behaves as a modified Chaplygin gas in the context of quintessence cosmology. We reconstructed the inflaton pote…
The universe dominated by the extended Chaplygin gas
E. O. Kahya, B. Pourhassan
In this paper, we consider a universe dominated by the extended Chaplygin gas which recently proposed as the last version of Chaplygin gas models. Here, we only consider the second…
