We have now observed three distinct charge density waves in the nematic superconductor, Ba1−xSrxNi2As2 (BSNA). This pnictide material has the same structure as the 122-phase FeAs superconductors, but contains Ni instead of Fe. Paglione’s group at the University of Maryland recently observed a sixfold enhancement of superconductivity in this material due to nematic fluctuations near […]

Center for Quantum Sensing and Quantum Materials awarded $12.6M by DOE
We were recently awarded a $12.6M Energy Frontier Research Center by the U.S. Department of Energy. With our partner, SLAC National Accelerator Laboratory, we will pioneer several new quantum sensing techniques for studying elementary phenomena in quantum materials. These will include a scanning qubit microscope, a time-of-flight instrument for detecting Einstein-Podolsky-Rosen pairs of electrons, and […]
