The lowest order constrained variational (LOCV) method for the many-body problems and its applications

M Modarres, A Tafrihi - Progress in Particle and Nuclear Physics, 2023 - Elsevier
One always looks for a simplified technique and desirable formalism, to solve the
Hamiltonian, and to find the wave function, energy, etc, of a many-body system. The lowest …

Dilatonic equation of hydrostatic equilibrium and neutron star structure

SH Hendi, GH Bordbar, B Eslam Panah… - Astrophysics and Space …, 2015 - Springer
In this paper, we present a new hydrostatic equilibrium equation related to dilaton gravity.
We consider a spherical symmetric metric to obtain the hydrostatic equilibrium equation of …

Influence of strong magnetic field on the structure properties of strange quark stars

F Kayanikhoo, K Naficy, GH Bordbar - The European Physical Journal A, 2020 - Springer
We investigate the thermodynamic properties of strange quark matter under the strong
magnetic field in the framework of the MIT bag model in two cases of bag constants. We …

Neutron star calculations with the phenomenological three-nucleon force

H Moeini, GH Bordbar - The European Physical Journal Plus, 2024 - Springer
In this work, we have studied the effect of three-nucleon interaction on the neutron stars
structure. In our calculations, we have considered the neutron star matter as a beta-stable …

Hot spin polarized strange quark stars in the presence of magnetic field using a density-dependent bag constant

GH Bordbar, Z Alizade - Astrophysics, 2014 - Springer
The effect of magnetic field on the structure properties of hot spin polarized strange quark
stars has been investigated. For this purpose, we use the MIT bag model with a density …
