The magnetoabsorption of large bipolarons is investigated using the path-integral method. The response of a bipolaron in a magnetic field to an external electromagnetic field is derived from a generalized anisotropic modeling influence phase in the framework of the memory-function approach. The resulting magnetoabsorption spectrum of large bipolarons is presented for several values of the magnetic field. A general feature is that this spectrum consists of a series of relatively narrow peaks. The peculiarities of the magnetoabsorption spectrum of the bipolaron as a function of the frequency of the electromagnetic field are attributed to the transitions involving scattering states of a bipolaron. The shape of the magnetoabsorption spectrum, due to free polarons at lower magnetic fields, drastically changes at higher magnetic fields where bipolarons are stable.

“…4,5 Particularly, it is well-known that a high-frequency electromagnetic field can strongly affect the scattering of conduction electrons and change electronic transport characteristics. 34,35 Recently, this approach was extended for the case of a twodimensional electron gas subjected to a purely dressing field which cannot be absorbed and emitted by conduction electrons.…”

Transport properties of a two-dimensional electron gas dressed by light

We show theoretically that the strong interaction of a two-dimensional electron gas (2DEG) with a dressing electromagnetic field drastically changes its transport properties. Particularly, the dressing field leads to the giant increase of conductivity (which can reach thousands of percents), results in nontrivial oscillating dependence of conductivity on the field intensity, and suppresses the weak localization of 2DEG. As a consequence, the developed theory opens an unexplored way to control transport properties of 2DEG by a strong high-frequency electromagnetic field. From experimental viewpoint, this theory is applicable directly to quantum wells exposed to a lasergenerated electromagnetic wave.
