Bogomol'nyi equations for Dirac-Born-Infeld cosmic string
Handhika Satrio Ramadhan, M Naufal Athaullah, Ilham Prasetyo
We revisit the question of whether Dirac-Born-Infeld (DBI) cosmic strings can admit Bogomol'nyi-Prasad-Sommerfield (BPS) configurations. Earlier work by Babichev et al. arXiv:0809.…
Some exact BPS solutions for exotic vortices and monopoles
Handhika S. Ramadhan
We present several analytical solutions of BPS vortices and monopoles in the generalized Abelian Maxwell-Higgs and Yang-Mills-Higgs theories, respectively. These models have recent…
On DBI Textures with Generalized Hopf Fibration
Handhika S. Ramadhan
In this letter we show numerical existence of O(4) Dirac-Born-Infeld (DBI) Textures living in (N +1) dimensional spacetime. These defects are characterized by …
Higher-dimensional DBI Solitons
Handhika S. Ramadhan
We study the theory of a (global) texture with DBI-like Lagrangian, the higher-dimensional generalization of the previously known chiral Born-Infeld theory. This model evades Derri…
Decay of flux vacua to nothing
Jose J. Blanco-Pillado, Handhika S. Ramadhan, Benjamin Shlaer
We construct instanton solutions describing the decay of flux compactifications of a gauge theory by generalizing the Kaluza-Klein bubble of nothing. The surface of the bubble…
Skyrme Branes
Jose J. Blanco-Pillado, Handhika S. Ramadhan, Noriko Shiiki
We obtain static selfgravitating solitonic 3-brane solutions in the Einstein-Skyrme model in 7D. These solitons correspond to a smooth version of the previously discussed cosmic p-…
