Roles of fast neutrino-flavor conversion on the neutrino-heating mechanism of core-collapse supernova

H Nagakura - Physical Review Letters, 2023 - APS
One of the greatest uncertainties in any modeling of the inner engine of core-collapse
supernova (CCSN) is neutrino-flavor conversions driven by neutrino self-interactions. We …

Evaluating approximate asymptotic distributions for fast neutrino flavor conversions in a periodic 1D box

I Padilla-Gay, I Tamborra, GG Raffelt - Physical Review D, 2022 - APS
In compact astrophysical objects, the neutrino density can be so high that neutrino-neutrino
refraction can lead to fast flavor conversion of the kind ν e ν¯ e↔ ν x ν¯ x with x= μ, τ …

Toward powerful probes of neutrino self-interactions in supernovae

PW Chang, I Esteban, JF Beacom, TA Thompson… - Physical Review Letters, 2023 - APS
Neutrinos remain mysterious. As an example, enhanced self-interactions (ν SI), which would
have broad implications, are allowed. At the high neutrino densities within core-collapse …

Basic characteristics of neutrino flavor conversions in the postshock regions of core-collapse supernova

H Nagakura, M Zaizen - Physical Review D, 2023 - APS
One of the active debates in core-collapse supernova (CCSN) theory is how significantly
neutrino flavor conversions induced by neutrino-neutrino self-interactions change the …

Multi-neutrino entanglement and correlations in dense neutrino systems

M Illa, MJ Savage - Physical Review Letters, 2023 - APS
The time evolution of multi-neutrino entanglement and correlations are studied in two-flavor
collective neutrino oscillations, relevant for dense neutrino environments, building upon …

Basic elements for simulations of standard-model physics with quantum annealers: Multigrid and clock states

M Illa, MJ Savage - Physical Review A, 2022 - APS
We explore the potential of D-Wave's quantum annealers for computing some of the basic
components required for quantum simulations of standard model physics. By implementing …
