JC Séamus Davis

from Wikipedia, the free encyclopedia

JC Séamus Davis (* around 1960) is an Irish-American experimental solid-state physicist who studies high-temperature superconductors .

Davis graduated from University College Cork with a bachelor's degree in physics in 1983 and received his PhD from the University of California, Berkeley in 1989 . In Berkeley he worked with Richard E. Packard . He then continued his research there and became Assistant Professor in 1993 and Professor in 2001. From 1998 to 2003 he was also at the Lawrence Berkeley National Laboratory (LBNL). In 2003 he became a professor at Cornell University , where he has been G. White Distinguished Professor from 2008 .

He is since 2007 Senior Physicist at Brookhaven National Laboratory and from 2009 director of the Center for Emergent Superconductivity the DOE . He has also been a Distinguished Research Professor of the Scottish Universities Physics Alliance (SUPA) at the University of St. Andrews since 2007 .

Davis dealt with, among other things, superfluid helium 3 (also in two-dimensional systems), suprasolidity and the investigation of the structure of high-temperature superconductors, using special scanning tunneling microscopes (STM) with Josephson junctions (Josephson tunneling microscope SJTM) developed in his laboratory . His group also developed other spectroscopic variants of STMs to visualize the electron wave functions in solid-state systems. This enabled him to determine the spatial distribution of the Cooper pair condensates in high-temperature superconductors in his laboratory.

In 2009 he received the Kamerlingh Onnes Prize , in 2001 the Outstanding Performance Award from the LBNL, in 2013 the Science Award from the Brookhaven National Laboratory and in 2005 the Fritz London Memorial Prize . He received the latter for his studies of weakly coupled arrays of superfluid helium 3, which showed a rich spectrum of phenomena such as quantum interference, and for the invention and development of spectroscopic STM imaging methods and their application to investigate the effects of individual atoms as an impurity or Doping, eddy-shaped electronic structures, interference effects of quasiparticles and alternative ordered states in copper high-temperature superconductors . In 1994 he was a Packard Fellow and received the National Science Foundation's Presidential Young Investigator Award . He is a member of the National Academy of Sciences (2010). In 1997 he was Miller Research Professor at Berkeley and he was Loeb Lecturer at Harvard.

He is a fellow of the American Physical Society and the Institute of Physics .
