From Homogeneous and Isotropic Universes to Braneworlds with Dynamical Tension Strings
AbstractCosmological solutions are studied in the context of the modified measure formulation of string theory, then the string tension is a...

Entanglement harvesting in cosmic string spacetime
We investigate the entanglement harvesting phenomenon for static detectors that locally interact with massless scalar fields in the cosmic string...

Superradiance and black resonator strings encounter helical black strings
We construct a cohomogeneity-1 helical black string in six-dimensional Einstein gravity. The helical solution branches from the onset of the...

The correspondence between rotating black holes and fundamental strings
The correspondence principle between strings and black holes is a general framework for matching black holes and massive states of fundamental...

A Note on Stress-Energy Tensor and Variational Principle for Null Strings
AbstractA straightforward application of the variational principle to null strings meets difficulties since string’s world-sheets are degenerate. It...

Imprints of a supercooled phase transition in the gravitational wave spectrum from a cosmic string network
A network of cosmic strings (CS), if present, would continue emitting gravitational waves (GW) as it evolves throughout the history of the Universe....

Gregory-Laflamme and superradiance encounter black resonator strings
We construct novel black strings that are neither time-translation invariant, nor axisymmetric, nor translationally invariant in the string...

On the Importance of Consideration of Initially-Extended Relativistic Strings for Hadronization Modeling
AbstractData from a number of experiments in high-energy physics indicate difficulties in the description of the production of pions and

Tameness, Strings, and the Distance Conjecture
The Distance Conjecture states that an infinite tower of modes becomes exponentially light when approaching an infinite distance point in field...

Strings in \(U(1)_L \times U(1)_L\) Simulations
As mentioned in the epigraph, fundamental superstrings were shown in [6] to behave in some ways similarly to cosmic strings, being one-dimensional...

A New Generation of Cosmic Superstring Simulations
Topological defects are an expected consequence of phase transitions in the early Universe. As such these objects, if detected,...

Vacuum Polarization in the Cosmic-String Background
AbstractWithin the framework of one-loop quantum gravity, we consider the vacuum polarization effect of the minimally-coupled massive scalar field...

4d strings at strong coupling
Weakly coupled regions of 4d EFTs coupled to gravity are particularly suitable to describe the backreaction of BPS fundamental axionic strings,...

Morris–Thorne-type wormhole with a cosmic string effects on harmonic oscillator problem
In this study, we explore quantum dynamics of non-relativistic particles within the context of a Morris–Thorne-type wormhole space-time featuring a...

The large D effective theory of black strings in AdS
We study black strings/funnels and other black hole configurations in AdS that correspond to different phases of the dual CFT in black hole...

London-Like Tensor Modes of Gravitational Waves in Cosmic String Cosmology
AbstractFrom a classical analysis, we show that gravitational waves in a cosmological medium with the equation of state parameter

An anisotropic rotating cosmic string with Lorentz violation: thermodynamics and Landau levels
In this work, we generalize the spacetime induced by a rotating cosmic string, taking into account anisotropic effects due to the breaking of the...

On the nature of cosmic strings in black hole spacetimes
A new model for cosmic strings (i.e. conical singularities) attached to black holes is proposed. These string are obtained by a explicit construction...

Impact of quintessence and cloud of strings on self-consistent d-dimensional charged thin-shell wormholes
This article evaluates the stability constraints of higher-dimensional geometry of thin-shell wormholes developed from the two equivalent copies of...

Shadows and quasinormal modes of the Bardeen black hole in cloud of strings
We investigate the black hole solution of Einstein’s gravity coupled with non-linear electrodynamics (NED) source in the background of a cloud of...
