Highlights in the press
Order on Command: Our recently published collaborative study Switching Magnetism and Superconductivity with Spin-Polarized Current in Iron-Based Superconductor [Seokhwan Choi et al., PRL 119, 227001 (2017).] was selected both as an Editor's Suggestion and for a feature in Physics. The work was also featured at phys.org.
Our article Aspects of electron-phonon interactions with strong forward scattering in FeSe Thin Films on SrTiO3 substrates lead by Dr. Yan Wang was selected as one of the highlights of 2017 by the journal Superconductor Science and Technology. The article will be free to read for 2017.
Rising Energy Costs It’s rare that additional fees are welcome, but as Steven Johnston and his colleagues explain in Nature Communications, sometimes they can actually be a pleasant surprise.
Good Vibrations - UT’s Steven Johnston and Colleagues Find that Phonons Boost Superconductivity in Iron Selenides.
High-temperature superconductivity: Electron mirages in an iron salt - Nature News and Views by J. Zaanen.
A sign-changing gap - Science Magazine Editor's Choice for Chi et al., Phys. Rev. B 89, 104522 (2014).
