Effect of superconducting fluctuations on ultrasound in unconventional superconductor
M. S. Mar'enko, C. Bourbonnais, A. -M. S. Tremblay
We study the renormalization of sound attenuation and sound velocity by fluctuation Cooper pairs in layered superconductors. We consider the influence of s- and d-wave symmetry of…
Neel order, ring exchange and charge fluctuations in the half-filled Hubbard model
J. -Y. P. Delannoy, M. J. P. Gingras, P. C. W. Holdsworth +1
We investigate the ground state properties of the two dimensional half-filled one band Hubbard model in the strong (large-U) to intermediate coupling limit ({\it i.e.} away from th…
Competition between Antiferromagnetism and Superconductivity in High Cuprates
David Senechal, P. -L. Lavertu, M. -A. Marois +1
Using variational cluster perturbation theory we study the competition between d-wave superconductivity (dSC) and antiferromagnetism (AF) in the the t-t'-t''-U Hubbard model. Large…
Higher order effective low-energy theories
A. L. Chernyshev, Dimitrios Galanakis, Philip Phillips +2
Three well-known perturbative approaches to deriving low-energy effective theories, the degenerate Brillouin-Wigner perturbation theory (projection method), the canonical transform…
