Hubbard vs. Emery model: spectra, transport and relevance for cuprates
JakÅ¡a VuÄiÄeviÄ, Rok Žitko
Understanding the transport properties of cuprate superconductors is one of the central challenges in the physics of strongly correlated electrons. The most common approach is to d…

Andreev bound state spectroscopy of a quantum-dot-based Aharonov-Bohm interferometer with superconducting terminals
Peter Zalom, Don Rolih, Rok Žitko
We analytically and numerically investigate an Aharonov-Bohm interferometer with two superconducting terminals and a strongly correlated quantum dot in one arm. Through a rigorous…

Systematic Schrieffer-Wolff-transformation approach to Josephson junctions: quasiparticle effects and Josephson harmonics
Ãdám Bácsi, Teodor IliÄin, Rok Žitko
We use the Schrieffer-Wolff transformation (SWT) to analyze Josephson junctions between superconducting leads described by the charge-conserving BCS theory. Starting from the singl…
