Coherent microwave emission of gain-driven polaritons

B Yao, YS Gui, JW Rao, YH Zhang, W Lu, CM Hu - Physical Review Letters, 2023 - APS
By develo** a gain-embedded cavity magnonics platform, we create a gain-driven
polariton (GDP) that is activated by an amplified electromagnetic field. Distinct effects of gain …

Cooling and Squeezing a Microwave Cavity State with Magnons Using a Beam Splitter Interaction

Q Xu, GD Fuchs - arxiv preprint arxiv:2410.00160, 2024 - arxiv.org
We propose two geometries to realize a significant beam splitter interaction (XZ coupling)
between magnons and a 2D microwave cavity mode. In both setups the cavity is analogous …
