New Massless Spectra from Cosmic String Cusps
Amelia Drew, Ivan Rybak
In the standard picture of cosmic strings, cusps are generic features of Nambu-Goto loops where the string momentarily reaches the speed of light. They have a characteristic sharp…
Decay of Nambu-Goto Cosmic String Loops via Coupling to a Massive Kalb-Ramond Field
I. Yu. Rybak
We study the dynamics of Nambu-Goto cosmic string loops coupled to a massive Kalb-Ramond field. This coupling provides a framework for describing the interaction between the cosmic…
Gravitational waves from cosmic strings in LISA: reconstruction pipeline and physics interpretation
Jose J. Blanco-Pillado, Yanou Cui, Sachiko Kuroyanagi +6
We initiate the LISA template databank for stochastic gravitational wave backgrounds sourced by cosmic strings. We include two templates, an analytical template, which enables more…
Stochastic Gravitational Wave Background from Chiral Superconducting Cosmic Strings
I. Yu. Rybak, L. Sousa
We investigate the emission of vector radiation by superconducting cosmic string loops, deriving general relations to characterize the vector radiation emission efficiency, and stu…
Testing classicality of gravity by gravitation decoherence
V. P. Stefanov, D. S. Mogilevtsev, I. Y. Rybak +1
Here we discuss an influence of an external weak gravitational field on the gravitational self-decoherence effect with help of the stochastic extension of regularized Shrödinger-N…
