SFB Seminar

Phase-dependent heat transport in superconducting circuits has recently received a lot of interest because it opens up the possibility to understand, control and manipulate heat flows at the nanoscale [1]. In this talk, I will discuss three examples of phase-coherent caloritronics namely heat transport in topological Josephson junctions [2], the role of Coulomb interactions on heat transport in a superconductor-quantum dot hybrid [3] and the possibility to realize a heat circulator in multi-terminal Josephson junctions [4].
