-We present a derivation of the Berry quantum adiabatic phase using group theory. Our formalism is used to discuss possible manifestations in Atomic Physics and to investigate the new cyclic quantum phase recently introduced by Aliaronov and Anandan. J. Physique 48 (1987) 1401-1406 SEPTEMBRE 1987,

The magnetization and the de Haas-van Alphen oscillations of Bloch electrons are calculated near commensurate magnetic fluxes. Two phases that appear in the quantization of mixed systems--the Berry phase and a phase first discovered by Wilkinson--play a key role in the theory.

High purity berry plasma membranes (PMs) of Vitis vinifera L. cv. Cabernet Sauvignon were isolated by two-phase partitioning of microsome fractions at different stages of berry ripening. PM proteins resolvable by the detergent cocktail of CHAPS and ASB-14 were separated by two-dimensional electrophoresis. A total of 119 protein spots from pre-véraison berry PMs on 2-D gels detected with silver ...

We introduce a particle-hole-symmetric metallic state of bosons in a magnetic field at odd-integer filling. This state hosts composite fermions whose energy dispersion features a quadratic band touching and corresponding 2π Berry flux protected by particle-hole and discrete rotation symmetries. We also construct an alternative particle-hole symmetric state-distinct in the presence of inversion ...

The first consistent analysis of asymptotic approximation of geometrical optics (GO) of electromagnetic waves in smoothly inhomogeneous isotropic media was made in a work by Rytov [1]. There he studied the GO in first approximation; also he gave a well-known law of rotation of polarization plane for electromagnetic wave. Geometrical attributes of this law were described further in detail by Vla...
