Abstract
A two-level system coupled by a coherent field is a ubiquitous model in atomic and molecular physics. While the resulting avoided crossing of light-dressed states has been extensively probed spectroscopically, such measurements typically reveal only the eigenenergies of the Hamiltonian. Here we present a mapping that also resolves the state populations, thus providing direct access to the amplitude coefficients of the eigenvectors. We demonstrate this in Rydberg states of cold rubidium atoms, combining population transfer spectroscopy with selective field ionization to map both the eigenvalues and the eigenvector amplitude coefficients of the coupled two-level system.Citation
