i have no idea of how to measure a berry phase
take a 1/2 spin in an external magnetic field
it is well known that this system can exhibit berry phase if the external magnetic field B takes a loop on the sphere.
but how to measure the berry phase?
how to separate the berry phase from the dynamical phase?
anyone have any idea?
