Collisional flavor pendula and neutrino quantum thermodynamics →

Neutrino flavor oscillation occurs because neutrinos emitted in a certain flavor are composed of a superposition of different neutrino mass states. In a dense enough environment, neutrino self-interactions synchronize flavor on large scales. In the two-flavor approximation, the resulting dynamics show similar behavior to the classical spinning top and inverted pendulum under some conditions. We explore the neutrino flavor pendulum with the addition of charged-current interactions and absorption/emission processes. In addition, investigating their effects in densities and time scales relevant to the isotropic and monochromatic emission of neutrinos from core-collapse supernovae, similar to neutrino the bulb model. We are able to identify the synchronized and bipolar modes of oscillation and constrain the polarization pendulum to a sphere and a circle in flavor space.

In 2023, Santiago has presented this research at the American Physical Society Far West Section, in San Diego.

Malika Golshan, Current student

Neutrinos, once thought to be massless according to the standard model, have proven otherwise due to the fascinating observation of neutrino flavor oscillations. In our research project, we take a unique approach by harnessing the power of machine learning to address a crucial question: Can computers aid in distinguishing between mass-bearing and massless neutrinos? By leveraging Convolutional Neural Networks (CNNs) on simulated weak lensing maps, our goal is to achieve a more accurate measurement of neutrino mass using cosmological methods.

I am deeply grateful to both my mentors. Vanessa, my initial mentor, provided me with a solid foundation and inspiration for this project. Adrian then became my mentor while transitioning to his postdoctoral position at Princeton. His unwavering dedication and expertise guided me through the intricacies of data analysis.

Discovering the origin of neutrino’s mass and their oscillation parameters could answer the matter antimatter asymmetry in our universe, and allow us to better understand astrophysics phenomena. Currently, multiple flagship experiments exploring neutrinos are underway, and to have full confidence in their results, accurate and precise neutrino nucleus cross sections are required. My project is to analyze data from lattice QCD calculations to determine one of these cross sections.
