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…
Strong-coupling theory of quantum dot Josephson junctions: role of the residual quasiparticle
Luka Pavešič, Ramón Aguado, Rok Žitko
We consider an interacting quantum dot strongly coupled to two superconducting leads in a Josephson junction geometry. By defining symmetry-adapted superpositions of states from th…
Quantum capacitance of a superconducting subgap state in an electrostatically floating dot-island
Filip K. Malinowski, R. K. Rupesh, Luka Pavešić +10
We study a hybrid device defined in an InAs nanowire with an epitaxial Al shell that consists of a quantum dot in contact with a superconducting island. The device is electrically…
Spectroscopy of spin-split Andreev levels in a quantum dot with superconducting leads
Arno Bargerbos, Marta Pita-Vidal, Rok Žitko +9
We use a hybrid superconductor-semiconductor transmon device to perform spectroscopy of a quantum dot Josephson junction tuned to be in a spin-1/2 ground state with an unpaired qua…
Entanglement between quasiparticles in superconducting islands mediated by a single spin
Juan Carlos Estrada Saldaña, Alexandros Vekris, Luka Pavešič +3
Condensed matter is composed of a small set of identical units, yet it shows an immense range of behaviour. Recently, an array of cold atoms was used to generate long-range quantum…
Qubit based on spin-singlet Yu-Shiba-Rusinov states
Luka Pavešić, Rok Žitko
The local magnetic moment of an interacting quantum dot occupied by a single electron can be screened by binding a Bogoliubov quasiparticle from a nearby superconductor. This gives…
Coupled Yu-Shiba-Rusinov states induced by a many-body molecular spin on a superconductor
Carmen Rubio-Verdú, Javier Zaldívar, Rok Žitko +1
A magnetic impurity on a superconductor induces Yu-Shiba-Rusinov (YSR) bound states, detected by tunneling spectroscopy as long-lived quasiparticle excitations inside the supercond…
