Explore a groundbreaking approach to fundamental physics research through this 20-minute conference talk that examines how Mössbauer spectroscopy can be revolutionized for detecting new interactions at sub-micrometer scales. Discover why nuclei serve as superior sensors compared to atoms, being substantially less susceptible to external electromagnetic perturbations and therefore ideal for investigations in distance ranges where atomic matter faces overwhelming background interference. Learn how researchers exploit the exceptionally narrow resonances characteristic of Mössbauer spectroscopy to achieve unprecedented sensing capabilities. Understand the connection between nuclear insensitivity to electromagnetic effects and the potential advantages nuclear clocks may offer over atomic clocks in future timekeeping applications. Delve into recent advances in the emerging field of nuclear quantum optics and its exotic applications. This presentation is part of the Simons Foundation's program supporting high-risk, potentially high-return small-scale experimental projects that aim for ambitious discoveries beyond current fundamental physics frontiers, focusing on table-top experiments suitable for typical university physics research laboratories.
