| Description | Speaker: Itay Bloch (Berkeley) Title: Quantum Magnetometry in search of Dark Matter Room: 3024 PSEL Host: Hsin-Chia Cheng Abstract: When bosonic DM have an ultra-light mass, they act as a classical, coherent field. In many cases, and specifically in some ALP models, this field has magnetic properties, and it can therefore be measured by quantum magnetometers. The Noble and Alkali Spin Detectors for Ultralight Coherent darK matter (NASDUCK) collaboration, was formed a few years ago in order to measure such DM. I will discuss the two publications of NASDUCK, each using well known techniques in magnetometry, albeit ones that were never used before in DM research. I will also discuss my ongoing work which proposes a new quantum magnetometry method, relying on utilizing quantum noise as an observable for DM research. This new metrological strategy has never been implemented before, even outside DM research, and may prove sensitive to DM models that were previously unreachable. |
