Fundamental Symmetries of the Early Universe and the Origin of Matter

This week I hosted Prof. Michael Ramsey-Musolf, Director of the Amherst Center for Fundamental Interactions,  who was visiting from UMass.-Amherst to give the MSU P&A Colloquium on “Fundamental Symmetries of the Early Universe and the Origin of Matter.” Abstract: Explaining why the universe contains more matter than antimatter remains an open problem at the interface of particle ...

Elementary Particles and Weak Interactions [BNL-443 (T-91)]

This technical note by Lee & Yang, first published in October 1957, is based on a series of lectures given in January 1957. Of particular note is “Section III.4 Static Electric Dipole Moment” on page 17 which indicated, perhaps for the first time, that non-zero EDMs would violate not only parity symmetry and but also ...

Lectures for PHY 451 Advanced Lab

Based on Teaching Students How to Model, I am revising the lectures for the Advanced Lab class (PHY 451). Day 1:  Introduce ourselves & fill out background material (year, classes & labs taken) Syllabus (timeline, grading policy, expectations) Introduction to Learning Goals & Modeling Framework Logbook (which kind, what to write) Description of experiments Choose Lab ...

Teaching Students How to Model

Heather Lewandowski of the University of Colorado, Boulder presented a Colloquium today about her group’s Physics Education Research titled “Engaging Students in Authentic Scientific Practices in Physics Lab Courses.” Her talk focused on how to teach students about models and modeling: which is just one of the four learning goals (modeling, design, communication, and technical lab ...

2017 University Undergraduate Research and Arts Forum

Six Spinlab undergraduate researchers will be presenting  on our research on April 7 as a part of MSU’s 2017 University Undergraduate Research and Arts Forum. Abstracts (links), titles, and locations for the posters (2) and talks (5) are below. Name: Kate Nezich Title: How to Make Atoms Glow: Characterization of Different LED’S for the Detection of Rare Nuclear Reaction Products ...

Laser Trap Monte Carlo Simulation

We have upgraded the Laser Trapping Monte Carlo to include a laser chirping feature.  This new feature allows for the addition of a linear frequency chirp to be added to any of the lasers in the simulation.  This is one of the first needed steps in being able to simulate slowing Radium-225 using its blue ...

Seminar @ Bucknell

Testing Time-Reversal Symmetry Using Lasers, a Magic Room, and Pear-Shaped Nuclei Experimental tests of fundamental symmetries using nuclei and other particles subject to the strong nuclear force have led to the discovery of parity (P) violation and the discovery of charge-parity (CP) violation. It is believed that additional sources of CP-violation may be needed to ...

Magnetic Field Map of Spinlab

This week I completed the Spinlab Magnetic Field Mapping Report, a 31-page LaTeX document outlining the motivation for mapping the magnetic field of the Spinlab, the process for building the components necessary for completing the mapping, and results from various mappings from 2016. This document will be very important for completing any future B-field mappings, especially once I ...

Righty Tighty, Lefty Loosey

The lab was confronted with a stuck knob on one of our Helium gas regulators. Many of the other lab members attempted to open the outlet valve to the regulator but that proved unsuccessful. I attempted to open the stuck valve as well, even using the strap wrench as shown. I had the thought that ...

HVPlotter in Python

Over the last week, I have developed a program in Python for quickly plotting data made from the exported data from the jhv4 labview program. The program has the user select which file they want to make plots from, and then opens the attached window. The user will then select the x-variable and y-variable they ...
