CNAM member and Emeritus Director Rick Greene has been featured on an Inside Science video about superconductivity, stemming from a special APS 2017 March Meeting session, "60 Years since BCS and 30 Years since Woodstock". Speaking about CNAM's research into high-temperature superconductivity, he describes superconductivity as “an emergent property of materials. It’s not something you can predict by knowing how a few atoms work or a few electrons work.” Inside Science is an editorially independent nonprofit science news service run out of the American Institute of Physics and supported by a coalition of underwriters, producing breaking news stories, features, essays, op-eds, documentaries, animations, and news videos.

CNAM and JQI member Vladimir Manucharyan has been selected for a 2017 Young Faculty Award by the Defense Advanced Research Projects Agency (DARPA). This program identifies and engages rising research stars in junior faculty positions at U.S. academic institutions and provides funding, mentoring and industry and DoD contacts to awardees to develop their research ideas in the context of DoD needs. Prof. Manucharyan's proposal, "Multi-terminal hybrid semiconductor/superconductor junctions", is aimed toward developing devices that will serve as robust building blocks of a topological quantum computer and act as test beds for topological effects predicted in exotic materials. Congrats Vlad!!!

An article by CNAM PhD candidate Daniel Campbell was published and chosen as an Editor's Suggestion in Phys. Rev. B. Campbell's synthesis of single crystals of binary FeAs, a spin density wave antiferromagnet with similarities to two families of unconventional superconductors, achieved the highest quality materials known to date, facilitating the first ever measurements of quantum oscillations in this system. Comparing experimental electronic structure to density functional theory calculations, the report addresses how the failure of theory to describe the magnetic structure of this compound may be tied to moderate correlations that have not been previously taken into account. This work is published in Phys. Rev. B.

CNAM's new 20 Tesla superconducting magnet system is now operational, having undergone installation and testing very recently. This adds to our facilities list one of only a handful of such superconducting magnets in the United States outside of the National High Magnetic Field Laboratories in Tallahassee and Los Alamos, and one of about twenty around the world. The new 20 T system, built by Oxford Instruments, also completes the formation of our new Extreme Quantum Environments Laboratory (EQEL). Supervised by CNAM Director Johnpierre Paglione, the EQEL facility allows researchers to perform quantum materials experiments at the extremes of temperature, magnetic field and pressure. In particular, synchronizing ultra-low temperature refrigeration to reach as low as 6 milliKelvin (6 thousandths of a degree above absolute zero), ultra-high diamond anvil cell apparatus to reach above megabar (1 million atmospheres) pressures, and ultra-high magnetic fields of 20 T (about 500,000 times the earth's field), the EQEL facility allows us to probe extremes of nature that have never before been studied.
