Genetic algorithm for the pair distribution function of the electron gas
Fernando Vericat, César O. Stoico, C. Manuel Carlevaro +1
The pair distribution function of the electron gas is calculated using a parameterized generalization of quantum hypernetted chain approximation with the parameters being obtained…
Incommensurate spin Luttinger liquid phase in a model for the spin-Peierls materials TiOBr and TiOCl
D. Mastrogiuseppe, C. Gazza, A. Dobry
In the present work we aim to characterize the lattice configurations and the magnetic behavior in the incommensurate phase of spin-Peierls systems. This phase emerges when the mag…
Competing Pairing Symmetries in a Generalized Two-Orbital Model for the Pnictides
Andrew Nicholson, Weihao Ge, Xiaotian Zhang +6
We introduce and study an extended "t-U-J" two-orbital model for the pnictides that includes Heisenberg terms deduced from the strong coupling expansion. Including these J terms ex…
Emergent complex neural dynamics
Dante R. Chialvo
A large repertoire of spatiotemporal activity patterns in the brain is the basis for adaptive behaviour. Understanding the mechanism by which the brain's hundred billion neurons an…
Quantum phase diagram of the half filled Hubbard model with bond-charge interaction
A. O. Dobry, A. A. Aligia
Using quantum field theory and bosonization, we determine the quantum phase diagram of the one-dimensional Hubbard model with bond-charge interaction in addition to the usual C…
Properties of a two orbital model for oxypnictide superconductors: Magnetic order, B_2g spin-singlet pairing channel, and its nodal structure
A. Moreo, M. Daghofer, J. A. Riera +1
A two orbital model for the new Fe-based superconductors is studied using the Lanczos method as well as pairing mean-field approximations. Our main goals are (i) to provide a compr…
