Quantum interference between vortex- and impurity-bound states boosts thermoelectricity
Erik Haatuft, Jacob Linder
Thermoelectric effects in superconductors are generally suppressed by the approximate particle-hole symmetry of the quasiparticle spectrum, but can become pronounced near defects t…
Real-space microscopic description of laser-pulse induced melting of superconductivity
Karl Bergson Hallberg, Guillermo Nava Antonio, Chiara Ciccarelli +1
Quenching quantum order via laser pulses has proven a useful tool to access exotic physical effects in systems that are strongly perturbed out of equilibrium. However, theoretical…
Josephson transistor and robust supercurrent enhancement with spin-split superconductors
Chi Sun, Jacob Linder
We theoretically investigate the supercurrent flow in a Josephson junction consisting of two spin-split superconductors combined by a normal metal weak link. The normal metal may b…
Voltage-tunable spin supercurrent nonreciprocity reaching 100% efficiency
Chi Sun, Johanne Bratland Tjernshaugen, Jacob Linder
The superconducting version of a diode effect has been the subject of extensive research in the past few years. So far, the focus has almost exclusively been on charge transport, b…
