Two-Field quintessential Higgs Inflation
Mehdi Eshaghi, Moslem Zarei, Ahmad Sheykhi
We study a two-field quintessential Higgs inflation model in which a quintessence field with an exponential potential is coupled to the Higgs field from the beginning…
CMB and reheating constraints to α-attractor inflationary models
Mehdi Eshaghi, Moslem Zarei, Nematollah Riazi +1
After Planck 2013, a broad class of inflationary models called α-attractors was developed which has universal observational predictions. For small values of the parameter α, the mo…
A Non-minimally Coupled Potential for Inflation and Dark Energy after Planck 2015: A Comprehensive Study
Mehdi Eshaghi, Moslem Zarei, Nematollah Riazi +1
In this work we introduce a new plateau-like inflationary model including a quadratic scalar potential coupled non-minimally to gravity. This potential has a dominant constant ener…
Bulk Viscosity and Particle Creation in the Inflationary Cosmology
Mehdi Eshaghi, Nematollah Riazi, Ahmad Kiasatpour
We study particle creation in the presence of bulk viscosity of cosmic fluid in the early universe within the framework of open thermodynamical systems. Since the first-order theor…
Lorentzian Wormholes in the Friedman-Robertson-Walker Universe
Behrouz Mirza, Mehdi Eshaghi, Shahram Dehdashti
The metric of some Lorentzian wormholes in the background of the FRW universe is obtained. It is shown that for a de Sitter space-time the new solution is supported by Phantom Ener…
