Gravitational Waves from Multiple Cosmic Superstrings and the Overshoot Problem
Luca Brunelli, Michele Cicoli, Muhammad Hassan +2
The paper analyzes how multiple species of cosmic superstrings in post‑inflationary string cosmology avoid the overshoot problem via friction from a gravitational‑wave radiation ba…
Dynamics of Cosmic Superstrings and the Overshoot Problem
Luca Brunelli, Michele Cicoli, Francisco Gil Pedro
We exploit the techniques of dynamical systems to study the cosmological evolution of cosmic fundamental strings and effective strings arising from branes wrapped on internal cycle…
The gravitational wave landscape of cosmic string networks with varying tension
Luca Brunelli, Filippo Revello, Gonzalo Villa
We fully classify the phenomenology of gravitational wave emission from scaling cosmic string networks with varying tension and compute the spectral indices of the resulting stocha…
Growth of Cosmic Strings with Field-Dependent Tension
Luca Brunelli
A novel mechanism to produce a cosmic network of fundamental superstrings based on a time-varying string tension has been recently proposed. It has been found that fundamental supe…
Growth of Cosmic Strings beyond Kination
Luca Brunelli, Michele Cicoli, Francisco G. Pedro
A novel mechanism for the production of a cosmic network of fundamental superstrings based on a time-varying string tension has been recently proposed in the context of a kinating…
Loop Blow-Up Inflation: a novel way to inflate with the Kähler moduli
Luca Brunelli
The topic of this talk is a new inflationary model in the context of Type IIB string compactifications called Loop Blow-Up Inflation, presented in arXiv:2403.04831. The original Bl…
