The two-terminal conductance of a random flux model defined on a square lattice is investigated numerically at the band center using a transfer matrix method. Due to the chiral symmetry, there exists a critical point where the ensemble averaged mean conductance is scale independent. We also study th

Through a very simple treatment we have constructed a lower bound for the statistical fluctuations of the survival probability of particles moving diffusively in a medium with random traps. We show that in the asymptotic regime the total survival probability is a non-self-averaging quantity, in that
We study the survival probability of a particle that performs a random walk in a medium with traps where the trapping strength V is distributed randomly. We use an approach which is asymptotically exact and brings Wn(s), the number of distinct sites s visited after n steps, into play. Particularly i
