Phys. Rev. D 35, 2597–2600 (1987)Some geometrical considerations of Berry’s phaseReceived 22 May 1986; published in the issue dated 15 April 1987 A group-theoretic treatment is given of the new phase found by Berry in the adiabatic evolution of a quantum-mechanical system in a finite-dimensional Hilbert space. It is shown how the Berry phases for the various eigenstates of the Hamiltonian are obtained from a set of angles associated with a group element. For the special case of a two-level system there is just one such angle which corresponds to the holonomy transformation associated with parallel transport around a closed curve on a sphere. © 1987 The American Physical Society URL:
