Carsten A. Ullrich is an Associate Professor of Physics at the University of Missouri-Columbia. He obtained his Ph.D. in theoretical physics in 1995 from the University of Würzburg, Germany. His main research interests are the fundamental and practical aspects of time-dependent density-functional theory, with an emphasis on transport, collective excitations, and excitonic effects in bulk and nanostructured semiconductor materials. In 2009 he was recognized as an Outstanding Referee by the American Physical Society.
Theory that takes into account the time-dependent nature of electronic transport through a quantum dot reveals fluctuations that could affect rapid switching of nanoscale electronic devices. Read More »
