Open AccessThe neutrino force in neutrino backgrounds: Spin dependence and parity-violating effects
The neutrino force results from the exchange of a pair of neutrinos. A neutrino background can significantly influence this force. In this work, we present a comprehensive calculation of the neutrino force in ...

Open AccessFermion pair radiation from accelerating classical systems
Accelerating classical systems that couple to a fermion-antifermion pair at the microscopic level can radiate pairs of fermions and lose energy in the process. In this work, we derive the generalization of the...

Open AccessNeutrino forces in neutrino backgrounds
The Standard Model predicts a long-range force, proportional to G F ...

Open AccessAccretion of dissipative dark matter onto active galactic nuclei
We examine the possibility that accretion of Dissipative Dark Matter (DDM) onto Active Galactic Nuclei (AGN) contributes to the growth rate of Super Massive Black Holes (SMBHs). Such a scenario could alleviate...

Open AccessDynamics of relaxed inflation
The cosmological relaxation of the electroweak scale has been proposed as a mechanism to address the hierarchy problem of the Standard Model. A field, the relaxion, rolls down its potential and, in doing so, s...

Open AccessExtending the scope of holographic mutual information and chaotic behavior
We extend the use of holography to investigate the scrambling properties of various physical systems. Specifically, we consider: (i) non-conformal backgrounds of black Dp branes, (ii) asymptotically Lifshitz blac...

Open AccessFluctuation and dissipation in de Sitter space
In this paper we study some thermal properties of quantum field theories in de Sitter space by means of holographic techniques. We focus on the static patch of de Sitter and assume that the quantum fields are ...

Open AccessA singlet extension of the MSSM with a dark matter portal
The minimal extension of the MSSM (NMSSM) has been widely studied in the search for a natural solution to the μ-problem. In this work, we consider a variation of the NMSSM where an additional singlet is added and...

Open AccessVector-like fields, messenger mixing and the Higgs mass in gauge mediation
In order to generate, in the context of gauge mediation, a Higgs mass around 126 GeV that avoids the little hierarchy problem, we explore a set of models where the messengers are directly coupled to new vector...

Open AccessStrong subadditivity, null energy condition and charged black holes
Using the Hubeny-Rangamani-Takayanagi (HRT) conjectured formula for entanglement entropy in the context of the AdS/CFT correspondence with time-dependent backgrounds, we investigate the relation between the bu...
