摘要
This paper discusses the possibility of using a dense Rydberg gas to study cooperative effects in the millimetre wave regime. Compared to a rotational transition, Rydberg-Rydberg transitions have enormous electric dipole transition moments and polarisabilities, which are sensitive to external and self-induced electric fields. In a dense Rydberg gas, a large group of molecules can share an electric field, and absorb and radiate cooperatively. A semiclassical calculation describes several significant cooperative effects in the time-domain and frequency-domain in two-level systems and Lambda-type three-level systems.
