ABSTRACT: The advent of scanning probe microscopy has provided the unique ability to investigate matter with ultimate precision. Single atoms and molecules can today not only be imaged with unprecedented resolution but also probed by local spectroscopy, manipulated to assemble functional nanostructures and excited to induce chemical change. In the present talk I will present our recent efforts to push the limit of scanning probe microscopy and spectroscopy by exploiting ultralow temperatures (10mK) and high magnetic fields (14T) as well as by developing novel vacuum interfaces for the controlled handling of large molecules with negligible vapor pressure. The experiments provide unprecedented microscopic details of single molecule and atom junctions, molecular quantum magnetism, single molecule electrodynamics and protein folding.  Many new perspectives ranging from quantum critical phenomena through molecular engineering to energy conversion are opened up by these developments.

BIO: Klaus Kern is Director and Scientific Member at the Max-Planck-Institute for Solid State Research in Stuttgart, Germany and Professor of Physics at the Ecole Polytechnique Fédérale de Lausanne (EPFL), Switzerland and honorary Professor at the University of Konstanz, Germany. His present research interests are in nanoscale science, self-ordering phenomena and in chemistry and physics of surfaces and interfaces. He holds a chemistry degree and PhD from the University of Bonn and an honorary doctor’s degree from the University of Aalborg. Subsequently he worked at the Research Center Jülich and and the Bell Laboratories before joining the Faculty of EPFL in 1991 and the Max-Planck-Society in 1998. Professor Kern has authored and coauthored 500 scientific publications, which have received nearly 20’000 citations. He has received numerous scientific awards and honors, including the 2008 Gottfried-Wilhelm-Leibniz Prize
