Microscopic electronic structure tomography of Rydberg macrodimers

Precise control and study of molecules is challenging due to the variety internal degrees freedom local coordinates that are typically not controlled in an experiment. Employing quantum gas microscopy position resolve atoms Rydberg macrodimer states solves almost all these challenges enables unique access molecular frame. Here, we demonstrate power this approach present first photoassociation studies for different symmetries which orientation relative applied magnetic field, polarization excitation light initial atomic state fully controlled. The observed characteristic dependencies allow electronic structure tomography state. We additionally observe orientation-dependent Zeeman shift reveal a significant influence on it caused by hyperfine interaction Finally, engineering electrostatic binding potential opening gap energetic vicinity two crossing pair potentials.
