Geometric phases in neutrino oscillations with nonlinear refraction
Lucas Johns, George M. Fuller
Neutrinos propagating in dense astrophysical environments sustain nonlinear refractive effects due to neutrino-neutrino forward scattering. We study geometric phases in neutrino os…
An optimization-based approach to calculating neutrino flavor evolution
Eve Armstrong, Amol V. Patwardhan, Lucas Johns +3
We assess the utility of an optimization-based data assimilation (D.A.) technique for treating the problem of nonlinear neutrino flavor transformation in core collapse supernovae.…
Lepton asymmetry, neutrino spectral distortions, and big bang nucleosynthesis
E. Grohs, George M. Fuller, C. T. Kishimoto +1
We calculate Boltzmann neutrino energy transport with self-consistently coupled nuclear reactions through the weak-decoupling-nucleosynthesis epoch in an early universe with signif…
CMB-S4 Science Book, First Edition
Kevork N. Abazajian, Peter Adshead, Zeeshan Ahmed +83
This book lays out the scientific goals to be addressed by the next-generation ground-based cosmic microwave background experiment, CMB-S4, envisioned to consist of dedicated teles…
Prospects for Neutrino Spin Coherence in Supernovae
James Y. Tian, Amol V. Patwardhan, George M. Fuller
We present neutrino bulb model simulations of Majorana neutrino coherent spin transformation (i.e., neutrino-antineutrino transformation), coupled to neutrino flavor evolution, for…
POLARBEAR-2: an instrument for CMB polarization measurements
Y. Inoue, P. Ade, Y. Akiba +83
POLARBEAR-2 (PB-2) is a cosmic microwave background (CMB) polarization experiment that will be located in the Atacama highland in Chile at an altitude of 5200 m. Its science goals…
