Theoretical Nuclear Physics

Title: High energy Research Project on the ATLAS experiment

Abstract: I will introduce today's high energy physics research programs and the ATLAS experiment at the Large Hadron Collider.

The research topics and activities at the Univ. of Michigan will be presented.




Oct. 26th, Prof. Jennifer Ogilvie

Ultrafast Optics and Spectroscopy

Title: Shedding New Light on Photosynthetic Systems Using Multidimensional Spectroscopies

Abstract: The primary events of photosynthesis occur on ultrafast timescales with high quantum efficiency. Elucidating the design principles of photosynthetic systems remains an outstanding challenge that has the potential to impact our design of artificial light-harvesting materials. I will discuss how coherent multidimensional spectroscopy can address open questions about photosynthetic systems and describe our recent progress in developing and using these tools to probe the mechanisms of ultrafast energy conversion in natural and artificial photosynthetic systems.

Theoretical Nuclear Physics

Title: The D-Term: Pressure To Find The Last Item On The Checklist

Abstract: The D-term is an interesting property of matter that has received a comparatively small amount of research dedicated to it compared to other global properties such as mass and spin. We discuss its potential connection to pressure and shear force distributions inside the nucleon and provide a possible means of extracting this form factor both theoretically and experimentally. We also provide a model calculation of both the A-term and D-term in ϕ3 theory, which required the modification of the energy-momentum tensor from its canonical definition to a renormalized "Improved" energy-momentum tensor.



Dec. 1st, Prof. Joshua Spitz

Experimental Neutrino Physics

Title: Neutrino Physics

Abstract: Some fundamental questions he seeks to answer through this research are:

  1. Are matter neutrinos different from antimatter neutrinos?

  2. How many neutrinos are there?

  3. What is the nature of the neutrino-matter interaction?

  4. How does the neutrino acquire mass?
