An artist's conception of the shock breaking out of a red supergiant star. The shock is caused by the collapse of the core of the star and initiates a type II supernova explosion.

Timothy C. Beers

Notre Dame Chair in Astrophysics

Astrophysicist Timothy Beers only needs 100 stars out of the 100 billion in the universe to help prove one of the longest-held theories in the field. However, finding those stars—the brightest, low-metallicity stars in the Milky Way— is like looking for a needle in a haystack.

Assistant Professor of Physics

Most research within the field of physics focuses on predicting the future. But how rapidly does our knowledge of the past deteriorate? Consider a sugar cube dissolving in water. “If you know the initial shape of the sugar cube, it is very easy to predict the concentration of sugar over time,” said Dervis Can Vural, assistant professor in the Department of Physics at Notre Dame. “But given the final state—a sweet cup of water—it is very difficult to ‘retrodict’ the original shape of the sugar cube. The process is irreversible and you’ve lost that information.”

Superconductors contain tiny tornadoes of supercurrent, called vortex filaments, that create resistance when they move. This affects the way superconductors carry a current.

But a magnet-controlled “switch” in superconductor configuration provides unprecedented flexibility in managing the location of vortex filaments, altering the properties of the superconductor.
