Berry’s phase for energy bands in solids 246831-Berry phase for energy bands in solids
D Berry phase in Bloch bands 1965 II Adiabatic Transport and Electric Polarization 1966 This review concerns applications of the Berry phase concept in solidstate physics In this field, we are typically interested in macroscopic phenomena which is slow band energy in place of the freeparticle dispersion Be Abstract The geometric structure of a singleparticle energy band in a solid is fundamental for a wide range of manybody phenomena and is uniquely characterized by the distribution of Berry curvature over the Brillouin zone We realize an atomic interferometer to measure Berry flux in momentum space, in analogy to an AharonovBohm(2 atoms/uc) BZ is halffilled #electrons in the reciprocal unit cell from the UvA VU Master Course Advanced Solid State Electronic Band Structure Wikipedia Berry phase for energy bands in solids
