Woodward part of research team that captures unique images of Io’s volcanoes

Posted December 6, 2021

Jupiter’s moon, Io, is one of the most volcanically active body in the solar system and yet, scientists have not been able to capture detailed images of volcanism and lava flows regularly. School of Physics and Astronomy Professor Charles “Chick” Woodward is part of a research team that was able to image four of Io’s volcanoes with greater detail than ever before from Earth based observatories. Io is over 390 million miles from the earth and the images enabled the team to resolve and study surface features less than 2 kilometers in size.

Furmanski part of collaboration that casts doubt on the so-called “sterile neutrino”

Posted October 27, 2021

Assistant Professor Andrew Furmanski, a faculty member in the School, is a member of a collaboration known as MicroBooNE, 170-ton liquid-argon detector at Fermilab, whose results have possibly eliminated the theorized “sterile neutrino.”

Wang finds unique properties by giving three layers of graphene a twist

Posted October 14, 2021

Ke Wang, an Assistant Professor in the School of Physics and Astronomy, led a recent experimental effort to study the electrical properties of a novel architecture of graphene--a single atomic layer of graphite. It was recently shown that by placing two layers of graphene on top of one another with a small twist angle in between, the electrical properties change drastically. “With a precisely-controlled twist angle,” Wang says, “it can even become superconducting, allowing electrical current to experience no dissipation or resistance.” Wang’s group took it to another level by stacking three layers of graphene with consecutive twists, resulting in a higher order atomic structure that exhibits “transport signature of superconductivity at an extremely low electron density, two orders of magnitude smaller than the previous record,” Wang says.

Roberta Humphreys on Luminous Blue Variables

Posted October 14, 2021

Professor Roberta Humphreys of the School of Physics and Astronomy recently gave a colloquium that served as a primer on “some of the most interesting stars I know: luminous blue variables (LBVs). These are among the most massive, most luminous stars known and in their short lifetimes experience high mass loss episodes that are not understood.

Greven research finds stretching quantum materials could tune their efficiency

Posted October 4, 2021

Professor Martin Greven, a Distinguished McKnight Professor in the University of Minnesota’s School of Physics and Astronomy and the Director of the Center for Quantum Materials, led research efforts that found that deformations in quantum materials that create an imperfection in their crystalline structure, can actually improve the material's superconducting and electrical properties.
