Workshop "Spin-dynamics and Kondo effects in STM"
14. - 16. 12. 2011
Hamburg
For more than 80 years renown physicists in Hamburg, like Otto Stern and Wolfgang Pauli, have contributed to the understanding of magnetic systems. Nowadays, the focus lies on the control of complex artificial nanosystems which requires the understanding of local spin, charge, and orbital quantum fluctuations of impurities and molecules on various types of substrates. These effects are now accessible with spin-polarized scanning tunneling microscopy and spectroscopy. The aim of this workshop is to bring together experts on the theory of spin and orbital quantum correlations in nanosystems, with experts on these new experimental advances, in order to understand future challenges in the field of quantum nano-spin-systems.
Organizers: Alexander Lichtenstein and Roland Wiesendanger
