Abstract

In this short communication, a new type of two-channel cavity QED model is derived. Two-channel models are important for they often lead to quantum interference phenomena. The previous models relied on the use of two or more modes of the quantized electromagnetic field, partially because of energy and parity restrictions. As it is shown in this work, such restrictions may be overcome with the use of properly chosen configurations of atomic levels and the aplication of classical external fields. Competing one- and two-photon processes involving one single mode may be obtained.
