Spectroscopy and wavefunctions

Two-tone and multi-photon spectroscopy, Floquet sidebands, avoided crossings, and the wavefunctions and quasiprobability distributions those spectra are signatures of. The shared shape: drive a frequency (or a photon number, or a drive strength) along one axis and read a response along another.
