The strong gravitational field around a proto-neutron star can modify the neutrino flavor transformations that occur above the neutrinosphere via three General Relativistic (GR) effects: time dilation, energy redshift, and trajectory bending. Depending on the compactness of the central object, the neutrino self-interaction potential is up to three times as large as that without GR principally due to trajectory bending which increases the intersection angles between different neutrino…

Coupling neutrino oscillations and simulations of core-collapse supernovae
• Physics
• 2020
At the present time even the most sophisticated, multi-dimensional simulations of core-collapse supernovae do not (self-consistently) include neutrino flavor transformation. This physics is missing
Neutrino flavor transformation in supernovae as a probe for nonstandard neutrino-scalar interactions
• Physics
Physical Review D
• 2018
We explore the possibility of probing the nonstandard interactions between the neutrino and a hypothetical massive scalar or pseudoscalar via neutrino flavor transformation in supernovae. We find
Spatiotemporal linear instability analysis of collective neutrino flavor conversion in four-dimensional spacetime
In an environment with high-density neutrinos formed in a core-collapse supernova (CCSN), the neutrinos exhibit nonlinear and complex oscillation behaviors due to their self-interactions. The onset
Fast neutrino-flavor conversion in the preshock region of core-collapse supernovae
• Physics
Physical Review Research
• 2020
We make a strong case that the fast neutrino-flavor conversion, one of the collective flavor oscillation modes, commonly occurs in core-collapse supernovae (CCSNe). It is confirmed in the numerical
Wave packet treatment of neutrino flavor oscillations in various spacetimes
• Physics
General Relativity and Gravitation
• 2021
We study the effect of gravity on neutrino flavor oscillations when each mass eigenstate is described by a wave packet instead of a plane wave. Two different approaches for implementing the wave
What can be learned from a future supernova neutrino detection
• Physics
• 2017
This year marks the thirtieth anniversary of the only supernova from which we have detected neutrinos - SN 1987A. The twenty or so neutrinos that were detected were mined to great depth in order to
Black hole interference patterns in flavor oscillations
• Physics
Physical Review D
• 2018
Motivated by neutrino astronomy, we consider a plane wave of coupled and massive flavours, scattered by a static black hole, and describe analytically and numerically the corresponding oscillation
GRQKNT code: General-Relativistic Quantum-Kinetics Neutrino Transport
We developed a new general-relativistic quantum-kinetics neutrino transport code, GRQKNT, for numerical studies of quantum kinetics of non-equilibrium neutrinos in six-dimensional phase space. This
Liouville term for neutrinos: Flavor structure and wave interpretation
• Physics
• 2018
Neutrino production, absorption, transport, and flavor evolution in astrophysical environments is described by a kinetic equation $D\varrho=-i[{\sf H},\varrho]+{\cal C}[\varrho]$. Its basic elements
