Solar-System Abundances of -Nuclides Probe Collective Neutrino Oscillations in Supernovae
Alexander Friedland, Derek J. Li, Giuseppe Lucente +3
Direct evidence for collective neutrino oscillations in core-collapse supernovae remains elusive. We show that this quantum phenomenon leaves a footprint on the abundance pattern o…
Neutrino helicity oscillations in astrophysical environments: A many-body approach
Yiheng Xu, Julien Froustey, George M. Fuller +2
Neutrino rest mass enables left-handed states to "flip" to right-handed states and vice versa. In-medium effects can enhance the probability for such spin-flip. We demonstrate that…
New Supernova Constraints on Vector-Mediated Neutrinophilic Dark Sector
Christopher V. Cappiello, P. S. Bhupal Dev, Amol V. Patwardhan
Supernova cooling has long been used to constrain physics beyond the Standard Model, typically involving new mediators or dark matter (DM) particles that couple to nucleons or elec…
Dark population transfer mechanism for sterile neutrino dark matter
George M. Fuller, Lukáš Gráf, Amol V. Patwardhan +1
We present a mechanism for producing a cosmologically-significant relic density of one or more sterile neutrinos. This scheme invokes two steps: First, a population of "heavy" ster…
Many-body collective neutrino oscillations: recent developments
Amol V. Patwardhan, Michael J. Cervia, Ermal Rrapaj +2
Neutrino flavor transformations in core-collapse supernovae and binary neutron star mergers represent a complex and unsolved problem that is integral to our understanding of the dy…
Collective neutrino oscillations with tensor networks using a time-dependent variational principle
Michael J. Cervia, Pooja Siwach, Amol V. Patwardhan +3
If a system of flavor-oscillating neutrinos is at high enough densities that neutrino-neutrino coherent forward scatterings are non-negligible, the system becomes a time-dependent…
Spectral splits and entanglement entropy in collective neutrino oscillations
Amol V. Patwardhan, Michael J. Cervia, A. B. Balantekin
In environments such as core-collapse supernovae, neutron star mergers, or the early universe, where the neutrino fluxes can be extremely high, neutrino-neutrino interactions are a…
Entanglement and collective flavor oscillations in a dense neutrino gas
Michael J. Cervia, Amol V. Patwardhan, A. B. Balantekin +2
We investigate the importance of going beyond the mean-field approximation in the dynamics of collective neutrino oscillations. To expand our understanding of the coherent neutrino…
A White Paper on keV Sterile Neutrino Dark Matter
R. Adhikari, M. Agostini, N. Anh Ky +133
We present a comprehensive review of keV-scale sterile neutrino Dark Matter, collecting views and insights from all disciplines involved - cosmology, astrophysics, nuclear, and par…
