Segregation and charge-density-wave order in the spinless Falicov-Kimball model
J. K. Freericks, R. Lemanski
The spinless Falicov-Kimball model is solved exactly in the limit of infinite-dimensions on both the hypercubic and Bethe lattices. The competition between segregation, which is pr…
Evidence for exhaustion in the conductivity of the infinite-dimensional periodic Anderson model
A. N. Tahvildar-Zadeh, M. Jarrell, Th. Pruschke +1
Monte Carlo-maximum entropy calculations of the conductivity of the infinite-dimensional periodic Anderson model are presented. We show that the optical conductivity displays anoma…
Experimental observations of non-equilibrium distributions and transitions in a 2D granular gas
J. S. Urbach, J. S. Olafsen
A large number (~10,000) of uniform stainless steel balls comprising less than one layer coverage on a vertically shaken plate provides a rich system for the study of excited granu…
Competition between phase separation and "classical" intermediate valence in an exactly solved model
Woonki Chung, J. K. Freericks
The exact solution of the spin-1/2 Falicov-Kimball model on an infinite-coordination Bethe lattice is analyzed in the regime of ``classical'' intermediate valence. We find (i) eith…
Approximate scaling relation for the anharmonic electron-phonon problem
J. K. Freericks, V. Zlatic, Mark Jarrell
An approximate scaling relation is found for the transition temperature to a charge-density-wave instability in the anharmonic electron-phonon problem, which maps a wide range of i…
Velocity Distributions & Density Fluctuations in a 2D Granular Gas
J. S. Olafsen, J. S. Urbach
Velocity distributions in a vibrated granular monolayer are investigated experimentally. Non-Gaussian velocity distributions are observed at low vibration amplitudes but cross over…
