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…
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…
Absence of the d-Density Wave State in 2D Hubbard Model
Alexandru Macridin, Mark Jarrell, Thomas Maier
Using the Dynamical Cluster Approximation (DCA) we calculate the alternating circulating-current susceptibility and investigate the transition to the d-density wave (DDW) order in…
Magnetism in semiconductors: A dynamical mean field study of ferromagnetism in Ga_{1-x}Mn_xAs
K. Aryanpour, J. Moreno, M. Jarrell +1
We employ the dynamical mean field approximation to perform a systematic study of magnetism in Ga_{1-x}Mn_xAs. Our model incorporates the effects of the strong spin-orbit coupling…
