A possible new phase of commensurate insulators with disorder: the Mott Glass
arXiv:cond-mat/9903340 · doi:10.1103/PhysRevLett.83.2378
Abstract
A new thermodynamic phase resulting from the competition between a commensurate potential and disorder in interacting fermionic or bosonic systems is predicted. It requires interactions of finite extent. This phase, intermediate between the Mott insulator and the Anderson insulator, is both incompressible and has no gap in the conductivity. The corresponding phase is also predicted for commensurate classical elastic systems in presence of correlated disorder.
