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…

Spin fluctuations in the 0.7-anomaly in quantum point contacts
Dennis H. Schimmel, Benedikt Bruognolo, Jan von Delft
It has been argued that the 0.7 anomaly in quantum point contacts (QPCs) is due to an enhanced density of states at the top of the QPC-barrier (van Hove ridge), which strongly enha…
