Simon, R and Mukunda, N (1993) Bargmann invariant and the geometry of the Guoy effect. In: Physical Review Letters, 70 (7). pp. 880-883.
We bring out the connection between Berry's geometric phase and a gauge invariant expression introduced by Bargmann. We exploit this relationship to show that the GÃ¼oy effect, which referes to the phase jump experienced by a focused beam as it crosses the caustic, is the geometric phase associated with the underlying Lobachevskian hyperbolic geometry.
