Seminarium Fizyki Ciała Stałego

A decade of experimental research on topological superconductivity insemiconducting nanowires coupled to superconductors didn't yieldconclusive evidence for their experimental realization.However recent advances in fabrication and understanding of thedevices led to two major advancements in the field. Thanks to couplingquantum dots through a hybrid semiconductor superconducting segment itwas possible achieve practical control over crossed Andreev reflection(CAR) and elastic co-tunneling (ECT) between two quantum dots. Duringthe seminar, I will discuss the observation of parallel spincomponents, depending on the interplay between the magnetic field andthe spin-orbit coupling in the nanowire device. I will also discusshow controlling CAR and ECT leads to a first realization of a minimalKitaev chain.Wang, G., Dvir, T., Mazur, G.P. et al.
