Since the formulation of the geometric phase by Berry, its relevance has been demonstrated in a large variety of physical systems. However, a geometric phase of the most fundamental spin-1/2 system, ...

Figure 1 shows a schematic of the experimental set-up as well as the level scheme. A cloud of laser-cooled 85 Rb atoms serves as the nonlinear optical medium, with the probe and coupling beams passing ...

Part 2 addresses coupling factor, signal propagation delay, maximum coupling, and vector analysis. Part 3 covers the derivation of parameters, including S parameters, and conclusions derived from this ...
