Transport in Inhomogeneous Strongly Correlated Systems
arXiv:cond-mat/0205057
Abstract
We consider an inhomogeneous strongly correlated system where external disorder divides it into mesoscopic cells.Strong inter-particle repulsion suppresses the quantum tunneling between cells and open a wide temperature range for incoherent transport.For a particular class of such inhomogeneous systems we find the low-energy transport to be free-fermion like when the constituent particles are spinless fermions.
