In today’s show we speak with doctoral researcher Mallika Randeria on her work in the Yazdani lab at Princeton University. As she explains in the interview, her research
explores the quantum behavior of electrons in a magnetic field. In fact, she uses a powerful scanning-tunneling microscope to actually image the electrons! Last year her group became the first to ever accomplished this and they got some astounding and (almost) unexpected results! Tune in to the show if you want to learn about the weird quantum behavior of electrons and what they actually look like up close when they’re exhibiting quantum effects, how a scanning-tunneling microscope works (and about the one here at Princeton), and some of Mallika’s other research imagining the phenomenon of superconductivity.

We welcome Mark Miller, a PhD candidate in Prof. Hultmark’s Gas Dynamics Lab, who knows all about the aerodynamics of wind turbines. Wind energy is a crucial component of the future’s energy landscape, but learning how to optimize their engineering is a work in progress. How should a windmill farm be laid out to maximize each turbine’s output? How can scientists model the air flow around windmills in lab-sized models? And finally, how does wind energy fit into the grid?
In this week’s installment of These Vibes, we spoke with Tamara Patton, doctoral researcher at the Woodrow Wilson School at Princeton and in the Nuclear Futures Lab, on her work using emergent technologies, specifically virtual reality, in nuclear arms control. She also delves in to the prospect of nuclear proliferation and arms control under the Trump presidency and the upcoming nuclear weapon ban treaty taking place this March at the UN.

This week features Jacob Schwartz, a PhD candidate in plasma physics here at Princeton, who brings us a deep concern: what should we do with our nuclear waste? Fission plants produce radioactive byproducts over time, and these concoctions will be dangerous to life for millennia. At the WIPP facility in New Mexico, scientists are testing many methods for safe storage of radioactive materials. Even more intriguingly, reports from WIPP contemplate strategies for warding off future civilizations, communicating across the centuries that an area is unhealthy to inhabit. How can we send messages on the timescales of the pyramids? How far do duty or ethics push us to confine our nuclear waste?
