Harmonic Thin-Shell Wormhole Supported by Metric-Dependent Equation of State
S. Danial Forghani
Abstract This short paper investigates the harmonic behavior of a general-relativistic thin-shell wormhole supported by a particular type of exotic fluid. The exotic fluid obeys a…
A Closed Universe: de Sitter Cosmic Gate
S. Danial Forghani, S. Habib Mazharimousavi
A new cosmological object in analogy with the concept of a wormhole in general relativity is introduced. As wormholes connect two distant points through a tunnel in spacetime, this…
A Geometrical Model for the Evolution of Spherical Planetary Nebulae Based on Thin-Shell Formalism
S. Danial Forghani, Ibrahim Gullu, S. Habib Mazharimousavi
A spherical planetary nebula is described as a geometric model. The nebula itself is considered as a thin-shell which visualized as a boundary of two spacetimes. The inner and oute…
Behavior of a Free Quantum Particle in the Poincaré Upper Half-Plane Geometry
Parham Dehghani, S. Habib Mazharimousavi, S. Danial Forghani
Inspired by the recent work of Filho et al., a Hermitian momentum operator is introduced in a general curved space with diagonal metric. The modified Hamiltonian associated with th…
Higher Dimensional Particle Model in Pure Lovelock Gravity
S. Danial Forghani, S. Habib Mazharimousavi, Mustafa Halilsoy
In this paper, based on the thin-shell formalism, we introduce a classical model for particles in the framework of dimensional -order pure Lovelock…
Thin-shell Wormholes with Ordinary Matter in Pure Gauss-Bonnet Gravity
S. Danial Forghani, S. Habib Mazharimousavi
In this paper, we introduce higher dimensional thin-shell wormholes in pure Gauss-Bonnet gravity. The focus is on thin-shell wormholes constructed by -dimensional spherical…
Thin-Shell Wormhole Satisfying Energy Conditions
S. Danial Forghani, S. Habib Mazharimousavi, Mustafa Halilsoy
The quartic self-interacting conformal scalar field is used to construct a thin-shell wormhole satisfying all energy conditions. Accompanying the scalar field is the extremal Reiss…
Discontinuity Problem in the Linear Stability Analysis of Thin-Shell Wormholes
S. Danial Forghani, S. Habib Mazharimousavi, Mustafa Halilsoy
We investigate the infinite discontinuity points of stability diagram in thin-shell wormholes. The square of the speed of sound ,\ which is expressed in terms of pressur…
Higher Dimensional Particle Model in Third-Order Lovelock Gravity
S. Danial Forghani, S. Habib Mazharimousavi, Mustafa Halilsoy
By using the formalism of thin-shells, we construct a geometrical model of a particle in third-order Lovelock gravity. This particular theory which is valid at least in 7 dimension…
Thermodynamic Stability of a Schwarzschild Thin-Shell Wormhole
S. Danial Forghani, S. Habib Mazharimousavi, M. Halilsoy
The thermodynamic stability of a thin-shell wormhole in a Schwarzschild bulk is considered. From the first law, entropy function is found which satisfies the local intrinsic stabil…
Fate of a Thin-Shell Wormhole Powered by Morris-Thorne Wormhole
S. Danial Forghani, S. Habib Mazharimousavi, M. Halilsoy
Asymmetric thin-shell wormholes from two traversable Morris-Thorne wormhole spacetimes, with identical shape but different redshift functions, are constructed. Energy density of th…
The Stability of Asymmetric Cylindrical Thin-Shell Wormholes
S. Danial Forghani, S. Habib Mazharimousavi, M. Halilsoy
In continuation of a preceding work on introducing asymmetric thin-shell wormholes as an emerging class of traversable wormholes within the context, this time cylindrically symmetr…
Asymmetric Thin-Shell Wormholes
S. Danial Forghani, S. Habib Mazharimousavi, M. Halilsoy
Spacetime wormholes in isotropic spacetimes are represented traditionally by embedding diagrams which were symmetric paraboloids. This mirror symmetry, however, can be broken by co…
Generalized Monge gauge
S. Habib Mazharimousavi, S. Danial Forghani, S. Niloufar Abtahi
Monge gauge in differential geometry is generalized. The original Monge gauge is based on a surface defined as a height function above a flat reference plane. The total cu…
