大家好！project Tyra在8月21日上午七點(台灣時間)邀請到朱炳翰博士(洛斯阿拉莫斯國家實驗室科學家)進行線上演講。 講題為「搜尋新物理的方法：使用原子」，歡迎大家來參與！ 摘要：This talk focuses on recent developments in test of fundamental physics, especially the matter-antimatter asymmetry and searches for dark matter and exotic interactions, using atoms. Recently, exotic spin-dependent interactions, predicted by many theoretical extensions of the Standard Model of particle physics, has attracted much attention in the community of physicists. Such theories are associated with the spontaneous breaking of continuous symmetries, leading to massless or very light Nambu-Goldston bosons such as the axion, axion-like-particles (ALPs), and hidden photons which are also candidates for cold dark matter. These exotic spin-dependent interactions can be described as the interaction of the effective magnetic field with the spin, which can be detected by sensitive magnetometers. I will present several novel experimental approaches to search for exotic spin-dependent interactions using various magnetometers, e.g., spin-exchange relaxation-free magnetometer, diamond quantum magnetometer, and polarized helium-3 gas. Additionally, I will also discuss the recent development of the cosmic axion searches at LANL using a LC circuit in a strong magnetic field detecting by a RF optically pumped magnetometer. 報名連結：https://www.eventbrite.com/e/tyra-talk-8202023-tickets-674794968917 --
