Dressing and Tuning-Dressing in a Bell-and-Bloom magnetometer. (MS Teams online seminar)

The first part of the seminar is devoted to discuss how an oscillating large magnetic field changes, dresses the Larmor frequency settled by a small static one. After  a short introduction on the mathematical tools needed to study the dynamical Larmor equations, we first discuss the well-known single field dressing and then the new tuning-dressing mechanism introduced recently (PRL 125, 093203  (2020)) obtained adding a second oscillating magnetic field to the previous ones.
In the second part we will present a Bell & Bloom magnetometer developed in our laboratory and some of its features, with emphasis to the noise reduction techniques and to measurements that can be performed on the basis of the dressing phenomenon.
