Keldysh Functional Renormalization Group Treatment of Finite-Ranged Interactions in Quantum Point Contacts
Lukas Weidinger, Jan von Delft
We combine two recently established methods, the extended Coupled-Ladder Approximation (eCLA) [Phys. Rev. B 95, 035122 (2017)] and a dynamic Keldysh functional Renormalization Grou…
Functional Renormalization Group treatment of the 0.7-analog in quantum point contacts
Lukas Weidinger, Christian Schmauder, Dennis H. Schimmel +1
We use a recently developed fRG method (extendend Coupled-Ladder Approximation) to study the 0.7-analog in quantum point contacts, arising at the crossing of the 1st and 2nd band a…
Functional Renormalization Group Approach for Inhomogeneous One-Dimensional Fermi Systems with Finite-Ranged Interactions
Lukas Weidinger, Florian Bauer, Jan von Delft
We introduce an equilibrium formulation of the functional renormalization group (fRG) for inhomogeneous systems capable of dealing with spatially finite-ranged interactions. In the…
