Neutrino quantum kinetics for fast flavor conversion in a time-dependent environment
Zewei Xiong, Meng-Ru Wu
Fast flavor conversions (FFCs) of neutrinos, driven by the fast flavor instability (FFI), can reshape the neutrino flavor content in dense astrophysical environments such as core-c…
Machine Learning Detection of Non-Axisymmetric Fast Flavor Instabilities in Compact Objects
Madhurima Chakraborty, Sajad Abbar, Meng-Ru Wu +2
The paper applies machine‑learning classifiers to identify non‑axisymmetric electron lepton number (ELN) crossings, which signal fast neutrino flavor instabilities, using angular m…
Collective neutrino-antineutrino pair oscillations
Shih-Jie Huang, Meng-Ru Wu
In dense neutrino gas, pairing correlations between neutrinos and antineutrinos with opposite momenta can be nonzero in generalized neutrino quantum kinetic equations at the mean-f…
Circumstellar Medium of Supernovae as New Probes for Feebly-interacting Particles
Yu Cheng, Chui-Fan Kong, Yen-Hsun Lin +2
We propose a novel strategy to probe feebly-interacting particles (FIPs) by exploiting the dense, confined circumstellar medium (CSM) surrounding core-collapse supernovae (CCSNe).…
Mapping the evolution of supernova-neutrino-boosted dark matter within the Milky Way
Yen-Hsun Lin, Meng-Ru Wu
Supernova-neutrino-boosted dark matter (SN BDM) has emerged as a promising portal for probing sub-GeV dark matter. In this work, we investigate the behavior of BDM signatures o…
Occurrence of fast neutrino flavor conversions in QCD phase-transition supernovae
Zewei Xiong, Meng-Ru Wu, Noshad Khosravi Largani +2
Core-collapse supernovae undergoing a first-order quantum chromodynamics (QCD) phase transition experience the collapse of the central proto-neutron star that leads to a second bou…
