Effect of the Coulomb repulsion and oxygen level on charge distribution and superconductivity in the Emery model for cuprates superconductors
Louis-Bernard St-Cyr, David Sénéchal
The Emery model (aka the three-band Hubbard model) offers a simplified description of the copper-oxide planes that form the building blocks of high-temperature superconductors. By…
Charge order and antiferromagnetism in twisted bilayer graphene from the variational cluster approximation
B. Pahlevanzadeh, P. Sahebsara, D. Sénéchal
We study the possibility of charge order at quarter filling and antiferromagnetism at half-filling in a tight-binding model of magic angle twisted bilayer graphene. We build on the…
Topological phases of the Kitaev-Hubbard Model at half-filling
J. P. L. Faye, S. R. Hassan, D. Sénéchal
The Kitaev-Hubbard model of interacting fermions is defined on the honeycomb lattice and, at strong coupling, interpolates between the Heisenberg model and the Kitaev model. It is…
-wave superconductivity in coupled ladders
J. P. L. Faye, S. R. Hassan, P. V. Sriluckshmy +2
We study the one-band Hubbard model on the trellis lattice, a two-dimensional frustrated lattice of coupled two-leg ladders, with hopping amplitude within ladders and betw…
Strong correlations in low dimensional conductors. What are they, and where are the challenges?
A. -M. S. Tremblay, C. Bourbonnais, D. Senechal
This paper is written as a brief introduction for beginning graduate students. The picture of electron waves moving in a cristalline potential and interacting weakly with each othe…
The spin-1 ladder : A bosonization study
D. Allen, D. Sénéchal
We construct a field-theoretic description of two coupled spin-1 Heisenberg chains, starting with the known representation of a single spin-1 chain in terms of Majorana fermions (o…
