Interactions between several types of cosmic strings
We study the interaction of several types of static straight cosmic strings, including local strings, global strings, and bosonic superconducting...

Dark photon dark matter from cosmic strings and gravitational wave background
Dark photon dark matter may be produced by the cosmic strings in association with the dark U(1) gauge symmetry breaking. We perform three-dimensional...

Primordial black hole archaeology with gravitational waves from cosmic strings
Light primordial black holes (PBHs) with masses smaller than 10 9 g (10 − 24 M ⊙ ) evaporate before the onset of Big-Bang nucleosynthesis, rendering their...

Gravitational waves from phase transitions and cosmic strings in neutrino mass models with multiple majorons
We explore the origin of Majorana masses within the majoron model and how this can lead to the generation of a distinguishable primordial stochastic...

Gravitational waves from global cosmic strings and cosmic archaeology
Global cosmic strings are predicted in many motivated extensions to the Standard Model of particle physics, with close connections to axion dark...

Probing the gravitational wave background from cosmic strings with the alternative LISA-TAIJI network
As one of the detection targets of all gravitational wave detectors today, the stochastic gravitational wave background (SGWB) provides an important...

Dark baryon from pure Yang-Mills theory and its GW signature from cosmic strings
We point out that SO(2 N ) pure Yang-Mills theory provides a candidate for dark matter (DM) without the explicit need to impose any additional...

Accelerating plane symmetric cosmological model with bulk viscous and cosmic strings in Lyra’s geometry
The present study deals with Lyra’s geometry in plane symmetric metric discussed in the presence of bulk viscous fluid, and one-dimensional strings...

Nambu Goto cosmic strings in the early universe
In this brief review, I discuss some of the effects of the Nambu Goto cosmic strings in the early universe. Nambu Goto strings are formed from...

Revisiting metastable cosmic string breaking
Metastable cosmic strings appear in models of new physics with a two-step symmetry breaking G → H → 1, where π 1 ( H ) ≠ 0 and π 1 ( G ) = 0. They decay via...

Quantum current dissipation in superconducting strings and vortons
In this work, the current stability is discussed for cosmic strings with the bosonic superconductivity. A non-vanishing curvature of string generally...

WGC and WCC for charged black holes with quintessence and cloud of strings
One of the important problems with the existence of weak gravity conjecture ( WGC ) is the violation of the cosmic censorship. Such a cosmic phenomena...

Coupling a Cosmic String to a TQFT
A common framework of particle physics consists of two sectors of particles, such as the Standard Model and a dark sector, with some interaction...

Probing the Nature of Cosmic Strings with Gravitational Waves
There is now compelling evidence that the fundamental interactions were once unified, but that, as the universe expanded and cooled, a series of...
