- Magnetohydrodynamics of Dirac Plasma in Graphene
- Time: 12:00 pm
- Place: 2241 Chamberlin Hall
- Speaker: Alex Levchenko, UW - Madison
- Abstract: Interactions between electrons in solid-state systems can lead to collective behavior described by hydrodynamics. One such system is the electron-hole plasma in graphene near the charge-neutrality point, which can form a strongly coupled Dirac fluid. In this talk, I will present results for hydrodynamic electron magnetotransport in graphene devices. In these systems, a distinct mechanism of magnetoresistance appears which is absent in systems with Galilean-invariant electron liquid. The resulting magnetoresistance depends on the intrinsic conductivity and viscosity of the electron liquid, and becomes especially pronounced near charge neutrality. This mechanism is related to Alfven's theorem on frozen-in magnetic field in magneto-hydrodynamics, according to which the motion of a perfectly conducting liquid perpendicular to the magnetic field lines is forbidden. In addition, we will consider thermoelectric phenomena and discuss hydrodynamic paradox in Corbino devices.
This talk is based on:

- Wisconsin's role in harnessing fusion energy
- Time: 7:00 pm - 8:00 pm
- Place: Discovery Building, DeLuca Forum and streaming; see for full details
- Speaker: Cary Forest , Physics, Realta Fusion
- Abstract: Fusion holds promise to provide abundant clean energy, but realizing this promise will require partners from academia, government, community organizations and the private sector. Cary Forest, professor of physics and co-founder of Realta Fusion, will explore recent breakthroughs in fusion energy and highlight Wisconsin’s role. He will also share the story of Realta Fusion, a UW-Madison startup with WARF support that seeks to use fusion to provide industrial process heat.
This event will held at the Discovery Building and on Zoom.
