Single-particle hopping probability on a chain with interaction and disorder by the modified Lanczos algorithm

We consider numerically a chain of ten sites (half filled) described by the Anderson-Hubbard model. The single-particle hopping probability is calculated as a function of disorder and correlation. A qualitative agreement for the logarithm of this hopping probability is found when compared with resul...

Description
Summary:We consider numerically a chain of ten sites (half filled) described by the Anderson-Hubbard model. The single-particle hopping probability is calculated as a function of disorder and correlation. A qualitative agreement for the logarithm of this hopping probability is found when compared with results of a calculation of the low-frequency conductivity by the Monte Carlo method.
