Keith C. Schwab
Professor of Applied Physics
B.A., University of Chicago, 1990; Ph.D., University of California, 1996. Associate Professor, Caltech, 2009-10; Professor, 2010-; Fletcher Jones Foundation Co-Director, Kavli Nanoscience Institute, 2013-15.
Professor Schwab's current focus is the development of novel quantum sensors and devices from the unique quantum properties of superfluid He-4. The goal to build matterwave interferometers, ultra-sensitive gyrometers, quantum bits, and quantum standards from this material which utilize the macroscopic quantum coherence and the ultra-low dissipation of this quantum state. Our aim is to impact both fundamental and practical science with these devices. We are developing superfluid Josephson junctions using novel 2d nanometerials with nanometer pores. This is a goal which has existed in this field for over 60 yrs.
Overview
Professor Schwab's current focus is the development of Josephson junctions for superfluid helium-4 with the goal to build quantum devices such as interferometers and quantum bits from this material. What makes this now possible are the advances in 2d nanometerials with nanometer pores.
