Title: Looking for Dark Matter with atomic clocks and magnetometers
Date (JST): Wed, Oct 31, 2018, 13:30 - 14:30
Place: Seminar Room A
Abstract: Conventional laboratory searches for dark matter are sensitive to a range of masses close to the weak scale, while new techniques are required to explore candidates outside this realm. In particular lighter candidates are difficult to detect due to their small momentum. Here we study two experimental set-ups which do not require transfer of momentum to detect dark matter: atomic clocks and co-magnetometers. These experiments probe dark matter that couples to the spin of matter via the very precise measurement of the energy difference between atomic states of different angular momenta. This coupling is possible (even natural) in most dark matter models, and we translate the current experimental sensitivity into implications for different dark matter models.
