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…
Pseudogap and antiferromagnetic correlations in the Hubbard model
Alexandru Macridin, Mark Jarrell, Thomas Maier +2
Using the dynamical cluster approximation and quantum monte carlo we calculate the single-particle spectra of the Hubbard model with next-nearest neighbor hopping . In the unde…
Phase separation in the Hubbard model
A. Macridin, M. Jarrell, Th. Maier
Phase separation in the Hubbard model is investigated with the dynamical cluster approximation. We find that it is present in the paramagnetic solution for values of filling smalle…
Physics of cuprates with the two-band Hubbard model - The validity of the one-band Hubbard model
A. Macridin, Th. Maier, M. Jarrell +1
We calculate the properties of the two-band Hubbard model using the Dynamical Cluster Approximation. The phase diagram resembles the generic phase diagram of the cuprates, showing…
Absence of superconductivity in the 2D Hubbard model
T. A. Maier, M. Jarrell, T. C. Schulthess +1
After receiving a number of comments and reviews from our colleagues who have suggested that our results could be greatly improved by other methods of extrapolation, we have decide…
Analytic continuation of QMC data with a sign problem
A. Macridin, S. P. Doluweera, M. Jarrell +1
We present a Maximum Entropy method (MEM) for obtaining dynamical spectra from Quantum Monte Carlo data which have a sign problem. By relating the sign fluctuations to the norm of…
