The Hubbard model on the triangular lattice: Spiral order and spin liquid
Peyman Sahebsara, David Sénéchal
We investigate the half-filled Hubbard model on an isotropic triangular lattice with the variational cluster approximation. By decreasing the on-site repulsion (or equivalently…
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…
Supersymmetry versus Gauge Symmetry on the Heterotic Landscape
Keith R. Dienes, Michael Lennek, David Sénéchal +1
One of the goals of the landscape program in string theory is to extract information about the space of string vacua in the form of statistical correlations between phenomenologica…
