On-demand thermoelectric generation of equal-spin Cooper pairs
Felix Keidel, Sun-Yong Hwang, Björn Trauzettel +2
Superconducting spintronics is based on the creation of spin-triplet Cooper pairs in ferromagnet-superconductor (F-S) hybrid junctions. Previous proposals to manipulate spin-polari…
Phase-coherent caloritronics with ordinary and topological Josephson junctions
Sun-Yong Hwang, Björn Sothmann
We provide a brief and comprehensive overview over recent developments in the field of phase-coherent caloritronics in ordinary and topological Josephson junctions. We start from t…
Phase-coherent heat circulator based on multi-terminal Josephson junctions
Sun-Yong Hwang, Francesco Giazotto, Björn Sothmann
We theoretically propose a phase-coherent thermal circulator based on ballistic multiterminal Josephson junctions. The breaking of time-reversal symmetry by either a magnetic flux…
Nonlinear heat transport in ferromagnetic-quantum dot-superconducting systems
Sun-Yong Hwang, David Sanchez
We analyze the heat current traversing a quantum dot sandwiched between a ferromagnetic and a superconducting electrode. The heat flow generated in response to a voltage bias prese…
Nonlinear electric and thermoelectric Andreev transport through a hybrid quantum dot coupled to ferromagnetic and superconducting leads
Sun-Yong Hwang, David Sanchez, Rosa Lopez
We discuss the nonlinear Andreev current of an interacting quantum dot coupled to spin-polarized and superconducting reservoirs when voltage and temperature biases are applied acro…
Thermoelectric effects in quantum Hall systems beyond linear response
Rosa Lopez, Sun-Yong Hwang, David Sanchez
We consider a quantum Hall system with an antidot acting as an energy dependent scatterer. In the purely charge case, we find deviations from the Wiedemann-Franz law that take plac…
