Suppression of Directional Light-Wave Mixing in Normal and Quantum Gases



Lu Deng, Chengjie Zhu, Edward W. Hagley, W R. Garrett


We discuss nonlinear optical processes in the presence of quantum gases. We show that in contrast to a normal gas where the medium “passively” participates in nonlinear optical processes, quantum gases “actively” interact with the wave mixing process by enforcing the properties of condensed-matter physics on the generation and propagation of new light fields. This manifestation of condensed-matter physics leads to intriguing suppression and enhancement effects in directionalwave generation and propagation processes that have no counterpart in a normal gas. This opens a new chapter on light-matter wave mixing and scattering; nonlinear optics with quantum gases.
