... the direct absorption curve, but as its first derivative. A typical resonance lineshape is illustrated in Fig. 2a. So far we have considered only a single unpaired electron whose interaction with its environment may be neglected. In most cases, however, the unpaired electrons are influenced by other ...

The most simple truncation scheme keeps track of the self-energy as well as of an effective Coulomb interaction U (i.e., the static part of the two-particle vertex). It yields flow equations for effective system parameters and can thus be regarded as an ...
