Keldysh Derivation of Oguri's Linear Conductance Formula for Interacting Fermions
Jan Heyder, Florian Bauer, Dennis Schimmel +1
We present a Keldysh-based derivation of a formula, previously obtained by Oguri using the Matsubara formalisum, for the linear conductance through a central, interacting region co…
On the relation between the 0.7-anomaly and the Kondo effect: Geometric Crossover between a Quantum Point Contact and a Kondo Quantum Dot
Jan Heyder, Florian Bauer, Enrico Schubert +5
Quantum point contacts (QPCs) and quantum dots (QDs), two elementary building blocks of semiconducting nanodevices, both exhibit famously anomalous conductance features: the 0.7-an…
Effect of spin-orbit interactions on the 0.7 anomaly in quantum point contacts
Olga Goulko, Florian Bauer, Jan Heyder +1
We study how the conductance of a quantum point contact is affected by spin-orbit interactions, for systems at zero temperature both with and without electron-electron interactions…
Towards combined transport and optical studies of the 0.7-anomaly in a quantum point contact
E. Schubert, J. Heyder, F. Bauer +5
A Quantum Point Contact (QPC) causes a one-dimensional constriction on the spatial potential landscape of a two-dimensional electron system. By tuning the voltage applied on a QPC…
Functional Renormalization Group Approach for Inhomogeneous Interacting Fermi-Systems
Florian Bauer, Jan Heyder, Jan von Delft
The functional renormalization group (fRG) approach has the property that, in general, the flow equation for the two-particle vertex generates independent variab…
