Abstract :

The waves that describe systems in quantum physics can carry information

about how their environment has been altered, for example by forces acting on

them. This effect is the geometric phase. It also occurs in the optics of polarised

light, where it goes back to the 1830s. The underlying mathematics is

geometric: the phenomenon of parallel transport, which also explains how

falling cats land on their feet, and why parking a car in a narrow space is

difficult. Incorporating the back-reaction of the geometric phase on the

dynamics of the changing environment exposes the unsolved problem of how

strictly a system can be separated from a slowly-varying environment, and

involves different mathematics: divergent infinite series.
