Electronic transport in a two-dimensional electron gas strongly coupled to light

We demonstrated theoretically that the strong coupling of a two-dimensional electron gas (2DEG) to a dressing electromagnetic field crucially changes electronic transport properties. It is shown that the dressing field leads to the giant increase of conductivity and nontrivial oscillating dependence of conductivity on the field intensity. Moreover, the dressing field suppresses the weak localization in 2DEG. As a result, the elaborated theory opens a substantially novel way to tune electronic transport properties with a strong high-frequency electromagnetic field.
