Detecting (high frequency) gravitational waves in a box
|講演者||Dr. Diego Blas (Universitat Autònoma de Barcelona)|
In the presence of a background EM field, the passage of GWs generate different modes in EM cavities by either their effect on the background field or by interacting with the boundaries of the cavity. In this talk, I will describe this process in some detail and show that these set-ups provide some of the best bounds for GWs in the MHz-GHz band. I shall finish by briefly describing the way GWs interact with spin systems.
