Probing electronic state-dependent conformational changes in a trapped Rydberg ion Wigner crystal
Researchers experimentally observed a state-dependent conformational change in a trapped ion Wigner crystal by laser-coupling a central ion to a Rydberg state. Tuning the system near a structural phase transition induced the crystal to switch from a linear to a zigzag configuration, revealing strong vibronic coupling and providing an experimental pathway for studying artificial molecular systems.
