Abstract

The stability of magnetic moments in a nanostructure against thermal and quantum fluctuations and the real-time dynamics of strongly excited nanosystems on metallic surfaces are studied theoretically on the basis of microscopic models addressing the degrees of freedom on the atomic level. To this end, different theoretical approaches and computational tools are employed and developed, such as classical Monte-Carlo simulations, quantum-classical hybrid dynamics and time-dependent density-matrix renormalization group.
