Neutrino-antineutrino superfluidity
Damiano F. G. Fiorillo, Georg G. Raffelt, Günter Sigl
Despite their feeble interactions, dense astrophysical neutrinos can behave collectively, exchanging flavor through waves of the neutrino plasma. Can collective interactions also i…
Neutron Star Bounds on Muonic Fifth Forces from Picometer to Meter Scales
Damiano F. G. Fiorillo, Alessandro Lella, Georg G. Raffelt +2
Testing muonic fifth forces is difficult because muons are scarce in ordinary matter. However, they are abundant in neutron stars. We show that this population responds coherently…
Production of Leptophilic Bosons in Ultradegenerate Relativistic Matter
Damiano F. G. Fiorillo, Alessandro Lella, Georg G. Raffelt +2
Neutron stars (NSs) are powerful factories for new particles with masses up to the 100~keV range. These compact stars contain significant amounts of protons, electrons, and muons.…
Magnetic Turbulence Boosts Supernova Signals of Axion-Photon Conversion
Damiano F. G. Fiorillo, Ángel Gil Muyor, Georg G. Raffelt +1
Magnetic fields between a supernova (SN) and Earth convert axions into gamma rays. The absence of such a signal in coincidence with SN 1987A neutrinos, using the coherent Milky Way…
Flavomons in Matter Gradients: Ray Tracing and Amplitude Evolution
Damiano F. G. Fiorillo, Georg G. Raffelt
Flavor instabilities develop in neutrino plasmas through the emission of flavomons, the quanta of flavor waves. Matter gradients can sweep flavomons across the unstable wave-number…
Quasi-linear theory of fast flavor instabilities in homogeneous environments
Damiano F. G. Fiorillo, Georg G. Raffelt
Dense neutrino plasmas can develop instabilities that drive collisionless flavor exchange, equivalent to the emission of flavomons, the quanta of flavor waves. We treat these waves…
