Physics Professor Finds that Phonons Boost Superconductivity in Iron Selenides

Assistant Professor Steven Johnston and his colleagues have found that given the right environment, an underdog superconductor can set records. The results of those efforts were published November 13 in a Nature Letter entitled “Interfacial mode coupling as the origin of the enhancement of Tc in FeSe films on SrTiO3.” To read more about the

Physics Professor Wins a Third NSF CAREER Grant For Department

Haidong Zhou, an assistant professor in physics and astronomy, is not a scientist who is easily daunted by frustration. In fact, his latest research deals with materials that have frustration built right in. The project, titled “Emergent Quantum Spin-Liquid in Yb-Pyrochlores and Yb-Spinels,” begins August 1 of this year and lasts for five years. The

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.
