NOvA experiment sees first long-distance neutrinos

Scientists, including a group of UT faculty and students, on the world’s longest-distance neutrino experiment have announced that they have seen their first neutrinos. Neutrinos are abundant in nature, but they very rarely interact with other matter. Studying them could yield crucial information about the early moments of the universe.

Physics Research Finds a Cooling Mechanism in Neutron Stars

When it comes to neutron stars, there really is more going on beneath the surface than you might suspect. Associate Physics Professor William R. (Raph) Hix and his colleagues have recently found a layer inside the crust of these stars that actually cools them down instead of heating them up, challenging common scientific perceptions.

UT Physics Team Involved in Nobel Prize-winning Higgs Boson Research

The Royal Swedish Academy of Sciences has awarded the Nobel Prize in physics to Peter Higgs and Francois Englert for their research on what has come to be called the Higgs field, which gives elementary particles mass. The UT High Energy Physics group has been part of the hunt for the Higgs boson since 2006, working with the Large Hadron Collider at CERN.

Physics Research Aims to Build Better Nanowire Networks

Nanowire networks have become very common in electronic devices. But given their scale, they can be tricky to make. Working with physics professor Hanno Weitering, graduate student Saban Hus set out to develop a new way to grow ultrathin wires in which the wires grow with equal distances between them. This can help streamline the process of making integrated circuits.

Nazarewicz Named UT-Battelle Corporate Fellow

Witold Nazarewicz, James McConnell Distinguished Professor of Physics, has been selected as a 2013 UT-Battelle Corporate Fellow. The rank of corporate fellow –among Oak Ridge National Laboratory’s highest honors—recognizes the researchers’ significant accomplishments and continuing leadership in their scientific, engineering and technological fields.

Physics Professor Reviews Iron-based Superconductors

Physics Professor Elbio Dagotto has written a review of new iron-based superconductors for the journal Reviews of Modern Physics. In his detailed colloquium citing hundreds of references, Dagotto points out how research into high-temperature superconductors has steadily advanced in a short period of time.
