Spin-Josephson effect in antiferromagnetic tunnel junctions
D. Chassé, A. -M. S. Tremblay
In the Josephson effect, coherent Cooper pair tunneling is driven by the phase difference between the superconducting order parameters on opposite sides of the junction. By analogy…
Low energy theory of the t-t'-t''-U Hubbard Model at half-filling: interaction strengths in cuprate superconductors and an effective spin-only description of La_2CuO_4
J. -Y. P. Delannoy, M. J. P. Gingras, P. C. W. Holdsworth +1
Spin-only descriptions of the half-filled one-band Hubbard model are relevant for a wide range of Mott insulators. In addition to the usual Heisenberg exchange, many new types of i…
Competition between charge and spin order in the extended Hubbard model on the triangular lattice
B. Davoudi, S. R. Hassan, A. -M. S. Tremblay
Several new classes of compounds can be modeled in first approximation by electrons on the triangular lattice that interact through on-site repulsion as well as nearest-neighbo…
Magnetism and d-wave superconductivity on the half-filled square lattice with frustration
Andriy H. Nevidomskyy, Christian Scheiber, David Senechal +1
The role of frustration and interaction strength on the half-filled Hubbard model is studied on the square lattice with nearest and next-nearest neighbour hoppings t and t' using t…
Convexity of the self-energy functional in the variational cluster approximation
Andriy H. Nevidomskyy, David Sénéchal, A. -M. S. Tremblay
In the variational cluster approximation (VCA) (or variational cluster perturbation theory), widely used to study the Hubbard model, a fundamental problem that renders variational…
Interaction-Induced Adiabatic Cooling for Antiferromagnetism in Optical Lattices
A. -M. Daré, L. Raymond, G. Albinet +1
In the experimental context of cold-fermion optical lattices, we discuss the possibilities to approach the pseudogap or ordered phases by manipulating the scattering length or the…
