Nambu-Goto Dynamics of Field Theory Cosmic String Loops
Jose J. Blanco-Pillado, Daniel Jiménez-Aguilar, Joanes Lizarraga +4
We perform a detailed comparison of the dynamics of cosmic string loops obtained in cosmological field theory simulations with their expected motion according to the Nambu-Goto act…
Parametric Resonances in Axionic Cosmic Strings
Jose J. Blanco-Pillado, Daniel Jiménez-Aguilar, Jose M. Queiruga +1
In this letter we uncover a new parametric resonance of axionic cosmic strings. This process is triggered by the presence on the string of internal mode excitations that resonantly…
The dynamics of Domain Wall Strings
Jose J. Blanco-Pillado, Daniel Jiménez-Aguilar, Jose M. Queiruga +1
We study the dynamics of domain wall solitons in field theories. These objects are extended along one of the spatial directions, so they also behave as strings; hence the…
Internal Excitations of Global Vortices
Jose J. Blanco-Pillado, Daniel Jiménez-Aguilar, Jose M. Queiruga +1
We investigate the spectrum of linearized excitations of global vortices in dimensions. After identifying the existence of localized excitation modes, we compute the decay ti…
Exciting the Domain Wall Soliton
Jose J. Blanco-Pillado, Daniel Jiménez-Aguilar, Jon Urrestilla
Many solitonic configurations in field theory have localized bound states in their spectrum of linear perturbations. This opens up the possibility of having long lived excitations…
Bubbles of Nothing and Supersymmetric Compactifications
Jose J. Blanco-Pillado, Benjamin Shlaer, Kepa Sousa +1
We investigate the non-perturbative stability of supersymmetric compactifications with respect to decay via a bubble of nothing. We show examples where this kind of instability is…
