FRG

Applying a generalization of the fRG to non-equilibrium transport [183] one can show that in the limit of high tunnel barriers the effective single-particle potential generated by the interplay of the contacts and the interaction is a superposition of two decaying oscillations with wave-lengths set by µL and µR .
Charge transport through single molecules, quantum dots, and quantum wires

An important ingredient missing in the current description using the (approximate) fRG for microscopic models are inelastic scattering processes resulting from the (Coulomb) interaction and leading to decoherence and dephasing at intermediate to large energies.

Assume, toward contradiction, that ǫfrg is not negligible in the security parameter k .
The Random Oracle Methodology, Revisited

It has become known as functional renormalization group (fRG) [6, 7, 8, 9]. A detailed description of the fRG will be given in the next section; here we make some principle remarks and discuss previous applications.
Functional renormalization group approach to zero-dimensional interacting systems

Different versions of the fRG have been developed over the last few years.
