Abstract:

What happens to a Mott insulator when you disorder it? Of the two energy scales: the Mott gap U and the antiferromagnetic scale J, which one is destroyed first? or together? We find that in 2 dimensions, sandwiched between a Mott insulator and an Anderson insulator, is an unusual spatially inhomogeneous metallic phase.
