Arne Brataas
Background and activities
Arne Brataas is the director of the Center of Excellence QuSpin (https://www.ntnu.edu/quspin).
Brataas received his Ph.D. in physics from the Norwegian University of Science and Technology in 1997. He has been a postdoctoral fellow at TU Delft (1997-1999) and Harvard University (1999-2002) and, since 2002, professor at his alma mater.
He was the chairman of the Kavli Prize Committee in Nanoscience (2013-2019) and a recipient of the 2015 ERC Advanced Grant.
His main interests are quantum transport and spin dynamics in insulators, semiconductors, metals, and superconductors.
