SINGLE-BOSON EXCHANGE REPRESENTATION OF THE FUNCTIONAL RENORMALIZATION GROUP FOR STRONGLY INTERACTING MANY-ELECTRON SYSTEMS

Single-boson exchange representation of the functional renormalization group for strongly interacting many-electron systems

We present a reformulation of the functional renormalization group (fRG) for many-electron systems, which relies on the recently introduced single-boson exchange (SBE) Western Trail representation of the parquet equations [F.Krien, A.Valli, and M.Capone, Phys.Rev.B 100, 155149 (2019)10.1103/PhysRevB.100.155149].The latter exploits a diagrammatic de

The INGV tectonomagnetic network

The Italian Istituto Nazionale di Geofisica e Vulcanologia (INGV) tectonomagnetic network was installed in Central Italy since the middle of 1989 to investigate possible magnetic anomalies related to earthquakes.The network is part of the INGV L'Aquila Geomagnetic Observatory and is located in an area extending approximately in latitude range
