Abstract:
We experimentally demonstrated 20 ladder climbing steps on the anharmonic intermolecular potential in the amino-acid microcrystals with an intense monocycle terahertz pulse. Absorption spectra show the suppression of the peak and enhancement of the low-frequency absorption for the incident electric field amplitude. These results are reproduced by simulations based on coherent transition processes between quantum levels in the anharmonic potential. The appearance of such nonlinearity allows us to control macroscopic motion via a phase-controlled terahertz pulse.
