Brane inflation in superstring theory predicts that cosmic strings (but not domain walls or monopoles) are produced towards the end of the inflationary epoch. Here, we discuss the production, the spectrum and the evolution of such cosmic strings, properties that differentiate them from those coming from an abelian Higgs model. As D-branes in extra dimensions, some type of cosmic strings will dissolve rapidly in spacetime, while the stable ones appear with a spectrum of cosmic string tensions. Moreover, the presence of the extra dimensions reduces the interaction rate of the cosmic strings in some scenarios, resulting in an order of magnitude enhancement of the number/energy density of the cosmic string network when compared to the field theory case.

  1. Cosmic superstrings in large volume compactifications: PTAs, LISA and time-varying tension

    astro-ph.CO 2025-04 conditional novelty 7.0 of 10

    Cosmic superstrings with a time-varying tension in large-volume string compactifications generically predict a LISA-band spectral drop and a high-frequency f^4 boost, encoding the mass and decay of the volume modulus.

  2. Probing the gravitational wave background from cosmic strings with LISA

    astro-ph.CO 2019-09 conditional novelty 6.0 of 10

    LISA is projected to probe cosmic string tensions G mu down to about 1e-17 and to measure spectral features from early-universe physics.

  3. Waveform Modelling for the Laser Interferometer Space Antenna

    gr-qc 2023-11 unverdicted novelty 2.0 of 10

    A review of existing waveform models for LISA sources and the challenges that must still be overcome.
