Not So Minimal Warm Inflation
Mar Bastero-Gil, Pedro García Osorio, António Torres Manso
An axion-like inflaton coupled to non-Abelian gauge bosons provides a compelling microphysical framework for warm inflation. Starting even from cold initial conditions, in these sy…
Isentropic thermodynamics across the hadron-quark mixed phase in a two-phase model with a PNJL quark description
Eduardo L. G. Salgado, Pedro Costa, Constança Providência
We study the hadron-quark mixed phase within a two-phase model for symmetric and asymmetric matter. For the quark sector we employ the (2+1) Polyakov-extended Nambu-Jona-Lasinio mo…
Extracting a Toponium Signal at the LHC with Spin and Quantum Information Tools
Laura Antozzi, Esteban Chalbaud, Frédéric Déliot +6
We investigate near-threshold top-antitop production at the LHC, focusing on the impact of toponium formation on spin correlations and quantum information properties of the final s…
Classical constant electric fields and the Schwinger effect in de Sitter
Mar Bastero-Gil, Paulo B. Ferraz, António Torres Manso +2
We study constant classical electric fields and the Schwinger effect in de Sitter space, with potential implications for magnetogenesis and inflationary dark matter production. Tre…
Schwinger Current in de Sitter Space
Mar Bastero-Gil, Paulo B. Ferraz, António Torres Manso +2
We study classical background electric fields and the Schwinger effect in de Sitter space. We show that having a constant electric field in de Sitter requires the photon to have a…
Comparing strange and non-strange quark stars within resummed QCD at NLO
Tulio E. Restrepo, Jean-Loïc Kneur, Constança Providência +1
We employ the renormalization group optimized perturbation theory (RGOPT) resummation method to evaluate the equation of state (EoS) for strange () and non-strange ($N_f=2…
