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…
Dynamical Breakup of the Fermi Surface in a doped Mott Insulator
M. Civelli, M. Capone, S. S. Kancharla +2
The evolution from an anomalous metallic phase to a Mott insulator within the two-dimensional Hubbard model is investigated by means of the Cellular Dynamical Mean-Field Theory. We…
Nucleation and crystallization process of silicon using Stillinger-Weber potential
Philippe Beaucage, Normand Mousseau
We study the homogeneous nucleation process in Stillinger-Weber silicon in the NVT ensemble. A clear first-order transition from the liquid to crystal phase is observed thermodynam…
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…
Self-vacancies in Gallium Arsenide: an ab initio calculation
Fedwa El-Mellouhi, Normand Mousseau
We report here a reexamination of the static properties of vacancies in GaAs by means of first-principles density-functional calculations using localized basis sets. Our calculated…
Binary continuous random networks
Normand Mousseau, G. T. Barkema
Many properties of disordered materials can be understood by looking at idealized structural models, in which the strain is as small as is possible in the absence of long-range ord…
Liquid-liquid phase transition in Stillinger-Weber silicon
Philippe Beaucage, Normand Mousseau
It was recently demonstrated that the Stillinger-Weber silicon undergoes a liquid-liquid first-order phase transition deep into the supercooled region (Sastry and Angell, Nature Ma…
Strong- and weak-coupling mechanisms for pseudogap in electron-doped cuprates
V. Hankevych, B. Kyung, A-M. Dare +2
Using the two-particle self-consistent approach and cluster perturbation theory for the two-dimensional t-t'-t''-U Hubbard model, we discuss weak- and strong-coupling mechanisms fo…
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…
Field-dependent diamagnetic transition in magnetic superconductor
R. Prozorov, D. D. Lawrie, I. Hetel +2
The magnetic penetration depth of single crystal was measured down to 0.4 K in dc fields up to 7 kOe. For insulating , Sm…
Stable fourfold configurations for small vacancy clusters in silicon from ab initio calculations
D. V. Makhov, Laurent J. Lewis
Using density-functional-theory calculations, we have identified new stable configurations for tri-, tetra-, and penta-vacancies in silicon. These new configurations consist of com…
The origin of the E+ transition in GaAsN alloys
V. Timoshevskii, N. Madini, M. Cote +1
Optical properties of GaAsN system with nitrogen concentrations in the range of 0.9-3.7% are studied by full-potential LAPW method in a supercell approach. The E+ transition is ide…
Heat Transport as a Probe of Electron Scattering by Spin Fluctuations: the Case of Antiferromagnetic CeRhIn5
Johnpierre Paglione, M. A. Tanatar, D. G. Hawthorn +6
Heat and charge conduction were measured in the heavy-fermion metal CeRhIn5, an antiferromagnet with T_N=3.8 K. The thermal resistivity is found to be proportional to the magnetic…
Cluster Dynamical Mean-Field Theory of the density-driven Mott transition in the one-dimensional Hubbard model
M. Capone, M. Civelli, S. S. Kancharla +2
The one-dimensional Hubbard model is investigated by means of two different cluster schemes suited to introduce short-range spatial correlations beyond the single-site Dynamical Me…
