Ulrich Schollwöck
Ulrich Schollwöck is a professor of theoretical physics at the Ludwig-Maximilians-Universität, Munich, Germany. He studied physics in Munich and Oxford, and received his Ph.D. in 1995 at the Service de Physique Theorique of the French Atomic Energy Commission (CEA), Saclay. He was a professor of physics at RWTH Aachen University from 2004 to 2009. His major interests in research are strongly correlated quantum systems in low dimensions and computational condensed matter physics. He is a fellow of the American Physical Society.
A little entanglement helps
A new algorithm allows for the extremely efficient calculation of thermally averaged quantities in one dimension, in conjunction with the density matrix renormalization group method. The key is the judicious selection of a few representative states. Read More »
