- Plasma Physics (Physics/ECE/NE 922) Seminar
- Exploring turbulence saturation in 3D plasmas
- Time: 12:05 pm
- Place: 2241 Chamberlin Hall
- Speaker: Dr. Benjamin Faber, Department of Engineering Physics, University of Wisconsin-Madison
- Abstract: Minimizing energy and particle losses due to microturbulence remains a significant challenge facing magnetic confinement fusion energy. In this talk, I will examine the physics of turbulence saturation in three-dimensional stellarator plasmas, highlighting recent theoretical and computational achievements. In particular, I will focus on turbulent saturation induced by nonlinear three-wave energy transfer between stable modes at the same scales as the driving instability, and show the three-wave coupling mechanism is dependent on local geometry. These insights into geometric dependence of saturation provides valuable input for future stellarator optimization schemes focused on reducing turbulent transport.
- NPAC (Nuclear/Particle/Astro/Cosmo) Forum
- Unlocking the Higgs portal with exotic Higgs decays
- Time: 12:30 pm
- Place: 5310 Chamberlin Hall
- Speaker: Verena Martinez, UMASS Amherst
- Abstract: Following the discovery of the Higgs boson at the Large Hadron Collider (LHC), a major goal is to characterize the properties of this new particle. The Higgs itself is a potential portal to new physics, providing connections between the Standard Model of particle physics and new phenomena, such as signatures of dark matter. Searches for new decays of the Higgs boson will be described using data collected by the ATLAS experiment and future prospects will be discussed.
