Abstract:
A new type of extremely short terahertz electromagnetic solitons, which can be formed in a system of molecules with permanent dipole moments in stationary states, has been predicted. It has been shown that such solitons can be formed when the ordinary component of the field excites quantum transitions and, in addition, the extraordinary component dynamically shifts their frequencies. The mechanism of propagation of such solitons in the presence of the nonstationary Stark inversion of quantum levels accompanied by the effective generation of a pulse of the extraordinary wave has been analyzed. The solitons under consideration have no analogs in the visible range.
