Manucharyan Wins DARPA Young Faculty Award

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!!!

CNAM Quantum Oscillations Study Highlighted

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.

New Ultra-High 20 Tesla Magnetic Field Facility Operational

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.

 

Rodriguez Overviews Materials Discovery Techniques at PhysicsNEXT

CNAM member Efrain Rodriguez described new x-ray techniques for monitoring solid-state reactions at the first of a new series of workshops called "Physics NEXT" hosted by the editors of the Physical Review. Focused on materials design and discovery, this workshop brought together equal numbers of theorists and experimentalists to discuss collaborative approaches to synthesize new or improved quantum materials.
