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 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…
Two-dimensional Hubbard-Holstein bipolaron
Alexandru Macridin, George. A. Sawatzky, Mark Jarrell
We present a diagrammatic Monte Carlo study of the properties of the Hubbard-Holstein bipolaron on a two-dimensional square lattice. With a small Coulomb repulsion, U, and with inc…
Kinetic energy driven pairing
Th. A. Maier, M. Jarrell, A. Macridin +1
Pairing occurs in conventional superconductors through a reduction of the electronic potential energy accompanied by an increase in kinetic energy, indicating that the transition i…
