Strong photon coupling to high-frequency antiferromagnetic magnons via topological surface states
Henrik T. Kaarbø, Henning G. Hugdal, Sol H. Jacobsen
We show strong coupling between antiferromagnetic magnons and microwave cavity photons at both high and externally controllable magnon frequencies. Using the fully quantum mechanic…
Dichroic cavity mode splitting and lifetimes from interactions with a ferromagnetic metal
Henning G. Hugdal, Eirik Jaccheri Høydalsvik, Sol H. Jacobsen
We study the effect of ferromagnetic metals (FM) on the circularly polarized modes of an electromagnetic cavity and show that broken time-reversal symmetry leads to a dichroic resp…
Cavity-mediated superconductor$\unicode{x2013}$ferromagnetic insulator coupling
Andreas T. G. Janssønn, Henning G. Hugdal, Arne Brataas +1
A recent proof of concept showed that cavity photons can mediate superconducting (SC) signatures to a ferromagnetic insulator (FI) over a macroscopic distance [Phys. Rev. B, 102, 1…
Macroscale non-local transfer of superconducting signatures to a ferromagnet in a cavity
Andreas T. G. Janssønn, Haakon T. Simensen, Akashdeep Kamra +2
Cavity spintronics recently heralded non-local magnonic signal transfer between magnetic samples. Here we show that by including superconductors in the cavity, we can make use of t…
Quasiclassical theory for the superconducting proximity effect in Dirac materials
Henning G. Hugdal, Jacob Linder, Sol H. Jacobsen
We derive the quasiclassical non-equilibrium Eilenberger and Usadel equations to first order in quantities small compared to the Fermi energy, valid for Dirac edge and surface elec…
Controlling superconducting spin flow with spin-flip immunity using a single homogeneous ferromagnet
Sol Jacobsen, Iryna Kulagina, Jacob Linder
Spin transport via electrons is typically plagued by Joule heating and short decay lengths due to spin-flip scattering. It is known that dissipationless spin currents can arise whe…
