The Effect of Randomness on the Mott State
arXiv:cond-mat/0701114 · doi:10.1103/PhysRevLett.99.186402
Abstract
We reinvestigate the competition between the Mott and the Anderson insulator state in a one-dimensional disordered fermionic system by a combination of instanton and renormalization group methods. Tracing back both the compressibility and the ac-conductivity to a vanishing kink energy of the electronic displacement field we do not find any indication for the existence of an intermediate (Mott glass) phase.
