Charge-induced maximal spin states of a polynuclear transition-metal complex
C. Romeike, M. R. Wegewijs, M. Ruben +2
We theoretically investigate the ground state spin of a polynuclear transition-metal complex as a function of the number of added electrons taking into account strong electron corr…
Spin blockade in a charge-switchable molecular magnet
C. Romeike, M. R. Wegewijs, H. Schoeller
We consider the effect of adding electrons to a single molecule on its magnetic properties and the resulting transport fingerprints. We analyze a generic model for a metal-organic…
Non-Linear Transport through a Molecular Nanojunction
Matthias H. Hettler, Herbert Schoeller, Wolfgang Wenzel
We present a simple model of electrical transport through a metal-molecule-metal nanojunction that includes charging effects as well as aspects of the electronic structure of the m…
An introduction to real-time renormalization group
Herbert Schoeller
This article presents a tutorial introduction to a recently developed real-time renormalization group method. It describes nonequilibrium properties of discrete quantum systems cou…
