High-resolution spectroscopy of 162Dy Rydberg levels

We carried out the first high-resolution spectroscopic survey of Rydberg levels in dysprosium ¹⁶²Dy, redefining its first ionization threshold with unprecedented precision, identifying more than 700 Rydberg states and assigning most of them to eight Rydberg series. These results lay the groundwork for future Dy-based quantum architectures and represent the first published result from our new Florence Dy platform.
