Tunable cooperativity in coupled spin-cavity systems

چکیده
We experimentally study the tunability of cooperativity in coupled spin--cavity systems by changing magnetic state spin system via an external control parameter. As model system, we use skyrmion host material Cu$_2$OSeO$_3$ to a microwave cavity resonator. In different phases measure dispersive coupling between resonator and magnon modes our results using input--output formalism. Our show strong normalized rate field, allowing us change magnon--photon from 1 60 at phase boundaries lattice state.

Living organisms can sense and respond to external and internal stimuli. Response isdemonstrated in many forms including modulation of gene expression profiles, motility,secretion, cell death, etc. Nevertheless, all forms share a basic property: they depend on sensingsmall changes in the concentration of an effector molecule or subtle conformational changes ina protein and invoking the appropri...
متن کاملA Tunable Waveguide-Coupled Cavity Design for Efficient Spin-Photon Interfaces in Photonic Integrated Circuits
A solid state emitter coupled to a photonic crystal cavity exhibits increased photon emission into a single frequency mode. However, current designs for photonic crystal cavities coupled to quantum emitters have three main problems: emitters are placed near surfaces that can degrade their optical properties, the cavity fluorescence cannot be collected into a single useful mode for further routi...

متن کاملTunable nonlocal spin control in a coupled-quantum dot system.
The effective interaction between magnetic impurities in metals that can lead to various magnetic ground states often competes with a tendency for electrons near impurities to screen the local moment (known as the Kondo effect). The simplest system exhibiting the richness of this competition, the two-impurity Kondo system, was realized experimentally in the form of two quantum dots coupled thro...
