- Abstract summary: Neutrino flavor transformations are driven by neutrino-neutrino coherent scattering, or in some cases, by collisional (incoherent) interactions.
An ensemble of neutrinos undergoing coherent scattering among themselves is an interacting quantum many-body system.
There is a tantalising prospect of quantum entanglement developing between the neutrinos, which can leave imprints on their flavor evolution histories.

- Abstract: 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 dynamics and nucleosynthesis in these environments.
The high number densities of neutrinos present in these environments can
engender various collective effects in neutrino flavor transformations, driven
either by neutrino-neutrino coherent scattering, or in some cases, through
collisional (incoherent) interactions. An ensemble of neutrinos undergoing
coherent scattering among themselves is an interacting quantum many-body system
-- as such, there is a tantalising prospect of quantum entanglement developing
between the neutrinos, which can leave imprints on their flavor evolution
histories. Here, we seek to summarize recent progress that has been made
towards understanding this phenomenon.

neutrino-neutrino coherent scattering can give rise to nontrivial quantum entanglement among neutrinos.
We observe that the entanglement induced by the coupling leads to strong delocalization in phase-space with largely non-Gaussian quantum fluctuations.
The link between the neutrino entanglement and quantum fluctuations is illustrated using the one- and two-neutrino entropy.

oscillations [0.0]
We find an intriguing connection between the entropy of entanglement of individual neutrinos with the rest of the ensemble.
For various types of neutrino spectra, we demonstrate that the entanglement entropy is highest for the neutrinos whose locations in the energy spectrum are closest to the spectral split(s)
This trend demonstrates that the quantum entanglement is strongest among the neutrinos that are close to these splits, a behavior that seems to persist even as the size of the many-body system is increased.
