Observation of inter-Landau-level quantum coherence in semiconductor quantum wells (2008)
Dani, K. M., Cotoros, I. A., Wang, J., Tignon, J., Chemla, D. S., Kavousanaki, E. G., ...
Using three-pulse four-wave-mixing femtosecond spectroscopy, we excite a non-radiative coherence between the discrete Landau levels of an undoped quantum well and study its dynamics. We observe...
