Inference of bipolar neutrino flavor oscillations near a core-collapse supernova, based on multiple measurements at Earth
Eve Armstrong, Amol V. Patwardhan, A. A. Ahmetaj +4
Neutrinos in compact-object environments, such as core-collapse supernovae, can experience various kinds of collective effects in flavor space, engendered by neutrino-neutrino inte…
Time dependent signatures of core-collapse supernova neutrinos at HALO
B. Ekinci, Y. Pehlivan, Amol V. Patwardhan
We calculate the response of a lead-based detector, such as the Helium and Lead Observatory (HALO) or its planned upgrade HALO-1kt to a galactic core-collapse supernova. We pay par…
Inference offers a metric to constrain dynamical models of neutrino flavor transformation
Eve Armstrong, Amol V. Patwardhan, Ermal Rrapaj +2
The multi-messenger astrophysics of compact objects presents a vast range of environments where neutrino flavor transformation may occur and may be important for nucleosynthesis, d…
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…
Eigenvalues and eigenstates of the many-body collective neutrino oscillation problem
Amol V. Patwardhan, Michael J. Cervia, A. Baha Balantekin
We demonstrate a method to systematically obtain eigenvalues and eigenstates of a many-body Hamiltonian describing collective neutrino oscillations. The method is derived from the…
On symmetries of Hamiltonians describing systems with arbitrary spins
Michael J. Cervia, Amol V. Patwardhan, A. B. Balantekin
We consider systems where dynamical variables are the generators of the SU(2) group. A subset of these Hamiltonians is exactly solvable using the Bethe ansatz techniques. We show t…
