- A Deep Look for New Physics with Neutrino Oscillations
- Time: 4:00 pm
- Place: 4274 Chamberlin Hall
- Speaker: Taritree Wongjirad, MIT
- Abstract: The study of the neutrino is currently one of most promising ways to search for beyond Standard Model Physics. Already, a beyond Standard Model effect has been observed wherein neutrinos transform from one type to another through a process known as neutrino oscillations. Through further measurements of neutrino oscillations, the field aims to answer additional open questions such as “do neutrinos and anti-neutrinos behave the same way?” and “how many types of neutrinos are there?”. The answers will impact not only our understanding of particle physics but also will influence our models of how the universe evolved. However, to get to these answers, neutrino experiments will need to move into an era of high-precision measurements. One way to achieve this is through the use of a detector known as a liquid argon time-projection chamber, or LArTPC. These detectors are capable of producing high-resolution images of neutrino interactions that can be used to reject backgrounds more effectively than past experiments. In this talk, I will describe the LArTPC experiments that will take place over the next decade and how they will aim to search for signs of a new type of neutrino and to measure CP-violation in the neutrino sector. I will describe some of the opportunities and challenges I have faced as a member of the MicroBooNE experiment, which is now successfully employing a LArTPC detector. In particular, I will describe efforts to analyze LArTPC data using Deep Learning.

- R. G. Herb Condensed Matter Seminar
- Semi-classical limit for the Schrodinger equation with lattice potential, and band-crossing
- Time: 10:00 am
- Place: 5310 Chamberlin
- Speaker: Qin Li , UW-Madison
- Abstract: In this talk we derive and compute the semi-classical limit of the Schrodinger equation with lattice potential. In [Gerard-Markowich-Mauser-Poupaud, Comm. Pure Appl. Math. 1997], the limit is derived under the assumption that energy bands are well-separated, namely, the system is adiabatic. However, in reality, this assumption is generically invalid. We remove the assumption, and obtain a general model by performing multi-scale variable separation with the Bloch decomposition and the Wigner transformation. Asymptotically this new full system recovers the old one in the adiabatic region. In the computation, we decompose the domain into regions depending on the distance to the energy band-crossing points, and apply associated schemes in different regions. A nature extension to the diabatic transition beyond the Born-Oppenheimer approximation will also be given at the end of the talk.
