We report the effect of the cosmological constant and the internal energy density of a cosmic
string on the deflection angle of light in the spacetime of a rotating cosmic string with internal …

This study is centered on examining the behavior of quantum particles governed by the
Schrödinger equation, particularly when subjected to a trigonometric Pöschl-Teller potential …

Cosmic strings may have formed in the early Universe due to the Kibble mechanism. While
string networks are usually modeled as being of Nambu-Goto type, this description is …

We use first-principles-derived numerical simulations to investigate the long-time evolution
of a half-quantum vortex ring, an Alice ring, arising from the decay dynamics of an isolated …

From the hydrodynamic viewpoint, the inclusion of viscosity in the theory of cosmic fluid may
appear as an abstraction. Using modern observational results for the Hubble parameter and …

The present work investigates several models of a single real scalar field, engendering
kinetic term of the Dirac–Born–Infeld type. Such theories introduce nonlinearities to the …

In this research contribution, we explore the relativistic quantum dynamics of spin-0 scalar
particles within a curved space-time background containing topological defects, while …

In this paper, we investigate novel kinklike structures in a scalar field theory driven by Dirac–
Born–Infeld (DBI) dynamics. Analytical features are reached through a first-order formalism …

We continue a comprehensive numerical study of semilocal string networks and their
cosmological evolution. These can be thought of as hybrid networks comprised of …

Les neutrinos, les rayons cosmiques chargés, et les photons de très haute énergie ainsi que
les ondes gravitationnelles fournissent des informations complémentaires pour étudier les …
