Orthorhombic copper polysilicate, CuSiO3, is isotypic to the spin-Peierls compound CuGeO3 and represents a further example of a quasi-one-dimensional spin = 1/2 antiferromagnetic Heisenberg chain system. This is a rep...
The influences of Dzyaloshinskii Moriya (DM) interaction and Kaplan-Shekhtman-Entinwohlman-Aharony (KSEA) interaction on the dimerization of a spin-Peierls system are investigated theoretically by using the Lanczo...

The quasi-one-dimensional spin-Peierls(SP)systems with impurities are studied in their bosonized form.The spins of the dimerized state are bounded into singlets with an SP gap,while the impurities of doped systems wil...
