Controlling superconductivity with the electromagnetic vacuum

MPSD Seminar
Exploiting light-matter interactions to control collective quantum phenomena in solids is an ongoing broad research effort. In particular, it is known that superconductivity can be strongly modified using an external radiation [1-3]. In the absence of the latter, it is an interesting question whether superconductivity induced by conventional Cooper pairing may be also affected by coupling phonons to the electromagnetic field confined in a cavity with enhanced vacuum fluctuations [4,5].

Cavity Optomagnonics

MPSD Seminar
Optomagnonics studies the quantum-coherent coupling of light to collective magnetic excitations in solid state systems. The magnetic material hosting the magnetic excitations can be also used as an optical cavity if patterned appropriately. This not only enhances the magnon-photon coupling (making these systems promising for applications in quantum technologies) but also allows studying cavity-modified light-matter interaction in a novel platform. In my talk I will go over the basics of cavity optomagnonics and present results on recent theory developments in my group, including optomagnonics with magnetic textures, optical heralding of magnon Fock states, and antiferromagnetic cavity optomagnonics.
