Benchmarking Quantum Annealing for a Greenhouse-Inspired Control QUBO
Hamzeh Alavirad, Maryam Bahrami Zanjani
We benchmark current annealing-based optimization workflows on a greenhouse-inspired quadratic unconstrained binary optimization problem for binary heater scheduling, where the hor…
Time-resolved digital quantum simulation of cosmological particle creation in a de Sitter-radiation transition
Hamzeh Alavirad
We present a time-resolved digital quantum simulation of cosmological particle creation in a de~Sitter--radiation FLRW transition. Instead of compiling only the final Bogoliubov tr…
Cosmological Constraints on Ghost Dark Energy in the Brans-Dicke Theory by Using MCMC Approach
Hamzeh Alavirad, Ahmad Sheykhi
By using a Markov Chain Monte Carlo simulation, we investigate cosmological constraints on the ghost dark energy (GDE) model in the framework of the Brans-Dicke (BD) theory. A comb…
Quintessence reconstruction of interacting HDE in a non-flat universe
Ahmad Sheykhi, Hamzeh Alavirad, Ali Bagheri +1
In this paper we consider quintessence reconstruction of interacting holographic dark energy in a non-flat background. As system's IR cutoff we choose the radius of the event horiz…
Observational constraints on G-corrected holographic dark energy using a Markov chain Monte Carlo method
Hamzeh Alavirad, Mohammad Malekjani
We constrain holographic dark energy (HDE) with time varying gravitational coupling constant in the framework of the modified Friedmann equations using cosmological data from type…
Modified gravity with logarithmic curvature corrections and the structure of relativistic stars
Hamzeh Alavirad, Joel M. Weller
We consider the effect of a logarithmic f(R) theory, motivated by the form of the one-loop effective action arising from gluons in curved spacetime, on the structure of relativisti…
Interacting generalized ghost dark energy in non-flat universe
Esmaeil Ebrahimi, Ahmad Sheykhi, Hamzeh Alavirad
We investigate the generalized Quantum Chromodynamics (QCD) ghost model of dark energy in the framework of Einstein gravity. First, we study the non-interacting generalized ghost d…
Topological Black Holes in Brans-Dicke-Maxwell Theory
A. Sheykhi, H. Alavirad
We derive a new analytic solution of -dimensional Brans-Dikce-Maxwell theory in the presence of a potential for the scalar field, by applying a conformal transformation to t…
Dark Energy From Fifth Dimension
H. Alavirad, N. Riazi
Observational evidence for the existence of dark energy is strong. Here we suggest a model which is based on a modified gravitational theory in 5D and interpret the 5th dimension a…
