Disorder Induced Quantum Phase Transition in Random-Exchange Spin-1/2 Chains
K. Hamacher, J. Stolze, W. Wenzel
We investigate the effect of quenched bond-disorder on the anisotropic spin-1/2 (XXZ) chain as a model for disorder induced quantum phase transitions. We find non-universal behavio…

Dynamics of spin correlations in the spin-1/2 isotropic XY chain in a transverse field
O. Derzhko, T. Krokhmalskii, J. Stolze
Dynamic xx spin pair correlation functions for the isotropic spin-1/2 XY chain are calculated numerically for long open chains in the presence of a transverse magnetic field at fin…
