The equation of a linear oscillator with adiabatically varying eigenfrequency ω(et) (e 1 is the adiabaticity parameter) is considered. The asymptotic solutions to the equation have been obtained to terms of order e3. It is shown that imaginary terms of order e2 form a generalized geometric phase determined by the geometry of the system's contour in the plane (ω, ω'). The real terms of orders e and e3, as predicted (Bliokh K Yu 2002 J. Math. Phys. 43 5624), do not form geometric amplitudes but…

On the change in electromagnetic wave polarization in a smooth one-dimensionally inhomogeneous medium

Propagation of an electromagnetic wave in a smooth one-dimensionally inhomogeneous isotropic medium is considered in the second approximation of geometrical optics. The polarization evolution is

The Hamilton ray equations giving a unified description for both the optical Magnus effect and the Berry phase have been derived and also a novel splitting effect for a ray of noncircular polarization has been predicted.

A linear set of ordinary differential equations with a matrix depending on a set of adiabatically varying parameters is considered. Its asymptotic solutions are constructed to an arbitrary accuracy

Geometric Phases in Physics

During the last few years, considerable interest has been focused on the phase that waves accumulate when the equations governing the waves vary slowly. The recent flurry of activity was set off by a

A quantal system in an eigenstate, slowly transported round a circuit C by varying parameters R in its Hamiltonian Ĥ(R), will acquire a geometrical phase factor exp{iγ(C)} in addition to the familiar

Angle variable holonomy in adiabatic excursion of an integrable Hamiltonian

If an integrable classical Hamiltonian H describing bound motion depends on parameters which are changed very slowly then the adiabatic theorem states that the action variables I of the motion are
