(H H Wills Physics Laboratory, University of Bristol, UK)
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.
