Transport properties and thermopower of the spinful Sachdev-Ye-Kitaev dot
Marco Uguccioni, Daniele Morotti, Luca Dell'Anna
We study the electric and thermoelectric transport through a spinful complex Sachdev-Ye-Kitaev (SYK) quantum dot coupled to metallic leads, forming a N-SYK-N junction, by the Keldy…

Keldysh field theory approach to direct electric and thermoelectric currents in quantum dots coupled to superconducting leads
Marco Uguccioni, Luca Dell'Anna
We study the transport properties of a quantum dot contacted to two superconducting reservoirs by means of the Keldysh field theory approach, showing how this technique allows us t…

Keldysh field theory approach to electric and thermoelectric transport in quantum dots
Marco Uguccioni, Luca Dell'Anna
We compute the current and the noise power matrix in a quantum dot connected to two metallic reservoirs by using the Keldysh field theory approach, a non-equilibrium quantum field…
