Superconducting quantum materials: from controllable thermo-spin effects to on-chip quantum magnonics

The family of quantum materials with emergent quantum properties controlled by external parameters is diverse and constantly growing. In this talk, I will demonstrate how to construct quantum materials from superconductors and ferromagnets. Heterostructures combining these materials feature non-trivial electronic properties leading to significant thermo-spin effects. These effects are promising for the possible new type of radiation detectors. Moreover, superconductor/ferromagnet nanostructures give rise to the novel family of magnon quantum materials. I will give an overview of recent experiments and the theory of hybrid magnon-polariton states in such systems. Finally, several perspective directions to develop on-chip quantum magnonics will be presented.
