Scaling behavior of an Anderson impurity close to the Mott-Anderson transition
M. C. O. Aguiar, V. Dobrosavljevic, E. Abrahams +1
The scaling behavior of Anderson impurity models each of which with a different site energy epsilon_i is examined close to the Mott-Anderson transition. Depending on the impurity e…
Short-Range Ordered Phase of the Double-Exchange Model in Infinite Dimensions
R. S. Fishman, F. Popescu, G. Alvarez +2
Using dynamical mean-field theory, we have evaluated the magnetic instabilities and T=0 phase diagram of the double-exchange model on a Bethe lattice in infinite dimensions. In add…
Hidden one-dimensional electronic structure and non-Fermi liquid angle resolved photoemission line shapes of -MoO
G. -H. Gweon, S. -K. Mo, J. W. Allen +4
We report angle resolved photoemission (ARPES) spectra of -MoO, a layered metal that undergoes two charge density wave (CDW) transitions at 109 K and 30 K. We have di…
Green functions for nearest- and next-nearest-neighbor hopping on the Bethe lattice
M. Kollar, M. Eckstein, K. Byczuk +8
We calculate the local Green function for a quantum-mechanical particle with hopping between nearest and next-nearest neighbors on the Bethe lattice, where the on-site energies may…
The Truncated Polynomial Expansion Monte Carlo Method for Fermion Systems Coupled to Classical Fields: A Model Independent Implementation
G. Alvarez, C. Sen, N. Furukawa +2
A software library is presented for the polynomial expansion method (PEM) of the density of states (DOS) developed by two of the authors (N.F. and Y. M.). The library provides all…
Effects of disorder on the non-zero temperature Mott Transition
M. C. O. Aguiar, V. Dobrosavljevic, E. Abrahams +1
The physics of the metal-insulator coexistence region near the non-zero temperature Mott transition is investigated in presence of weak disorder. We demonstrate that disorder reduc…
