Spin-fluctuations and unconventional superconductivity in heterostructures of magnetic insulators and gapless fermion systems

22.11.2022 13:00 – 14:30

Heterostructures involving magnetic insulators (MIs) and normal metals (NMs) have been of enormous interest for some time. One particularly appealing aspect of such system is the possibility to design superconducting systems by sandwiching NMs and MIs and proximity coupling them via an exchange interaction. In this talk I will present theoretical work on such spin-fluctuations mediated superconductivity in NMs coupled to antiferromagnetic MIs as well as to MIs with non-coplanar spin ground states. Both types of systems feature a rich superconducting phase diagram involving unconventional superconductivity. The latter systems also feature the possibility of exhibiting topological superconductivity.
