Spinodal Gravitational Waves
Yago Bea, Jorge Casalderrey-Solana, Thanasis Giannakopoulos +5
We uncover a new gravitational-wave production mechanism in cosmological, first-order, thermal phase transitions. These are usually assumed to proceed via the nucleation of bubbles…
Spin-1/2 "bosons'' with mass dimension 3/2 and fermions with mass dimension 1 cannot represent physical particle states
A. R. Aguirre, M. M. Chaichian, B. A. Couto e Silva +1
We delve into the first principles of quantum field theory to prove that the so-called spin-1/2 ''bosons'' and the fermions with mass dimension 1, including ELKO, cannot represent…
Gravity duals for defect quivers in the Veneziano limit
Niko Jokela, José Manuel Penín, Konstantinos Christos S. Rigatos
We construct gravity duals to supersymmetric gauge theories in the presence of unquenched flavor hypermultiplets in the fundamental representation of the gauge group living on the…
Flavored ABJM theory on the sphere and holographic F-functions
Niko Jokela, Jani Kastikainen, Elias Kiritsis +1
We study strongly coupled ABJM theory on the 3-sphere with massive quenched flavor using the AdS/CFT correspondence. The holographic dual consists of type IIA supergravity with pro…
Holographic approach to compact stars and their binary mergers
Carlos Hoyos, Niko Jokela, Aleksi Vuorinen
In this review article, we describe the role of holography in deciphering the physics of dense QCD matter, relevant for the description of compact stars and their binary mergers. W…
Domain Collisions
Yago Bea, Jorge Casalderrey-Solana, Thanasis Giannakopoulos +3
We use holography to study collisions of phase domains formed in a four-dimensional, strongly-coupled gauge theory with a first-order, thermal phase transition. We find three quali…
