Interchain Coupling Effects and Solitons in CuGeO3
Jun Zang, Sudip Chakravarty, A. R. Bishop
Abstract
The effects of interchain coupling on solitons and soliton lattice structures in CuGeO3 are explored. It is shown that interchain coupling substantially increases the soliton width and changes the soliton lattice structures in the incommensurate phase. It is proposed that the experimentally observed large soliton width in CuGeO3 is mainly due to interchain coupling effects.
