Advanced materials for magnetic cooling:fundamentals and practical aspects
Mohamed Balli, Serge Jandl, Patrick Fournier +1
Over the last two decades, the research activities on magnetocalorics have been exponentially increased leading to the discovery of a wide category of materials including intermeta…
Modeling multiorbital effects in Sr2IrO4 under strain and a Zeeman field
Lena Engström, T. Pereg-Barnea, William Witczak-Krempa
We present a comprehensive study of a three-orbital lattice model suitable for the layered iridate Sr2IrO4. Our analysis includes various on-site interactions (including Hubbard an…
Predominance of non-adiabatic effects in zero-point renormalization of the electronic band gap
Anna Miglio, Véronique Brousseau-Couture, Emile Godbout +6
Electronic and optical properties of materials are affected by atomic motion through the electron-phonon interaction: not only band gaps change with temperature, but even at absolu…
Accelerated impurity solver for DMFT and its diagrammatic extensions
Corey Melnick, Patrick Sémon, Kwangmin Yu +3
We present ComCTQMC, a GPU accelerated quantum impurity solver. It uses the continuous-time quantum Monte Carlo (CTQMC) algorithm wherein the partition function is expanded in term…
Geometric entanglement in integer quantum Hall states
Benoit Sirois, Lucie Maude Fournier, Julien Leduc +1
We study the quantum entanglement structure of integer quantum Hall states via the reduced density matrix of spatial subregions. In particular, we examine the eigenstates, spectrum…
Real Space Raman Spectroscopy of Graphene Isotope Superlattices
Eric Whiteway, Martin Lee, Michael Hilke
We report the Raman spectroscopy of 12C/13C graphene isotope superlattices synthesized by chemical vapour deposition. At large periods the Raman spectra corresponds to the sum of t…
Impurities in 3D quadratic band-touching Luttinger semimetals : Friedel and RKKY oscillations
Louis J. Godbout, Serguei Tchoumakov, William Witczak-Krempa
We investigate the response of 3D Luttinger semimetals to localized charge and spin impurities as a function of doping. The strong spin-orbit coupling of these materials strongly i…
Temperature dependence of the topological phase transition of BiTeI from first principles
Véronique Brousseau-Couture, Gabriel Antonius, Michel Côté
A topological phase transition from a trivial insulator to a topological insulator requires the bulk band gap to vanish. In the case of noncentrosymmetric materials,…
Interaction and temperature effects on the magneto-optical conductivity of Weyl liquids
S. Acheche, R. Nourafkan, J. Padayasi +2
Negative magnetoresistance is one of the manifestations of the chiral anomaly in Weyl semimetals. The magneto-optical conductivity also shows transitions between Landau levels that…
Phonon magnetochiral effect of band-geometric origin in Weyl semimetals
Sanghita Sengupta, M. Nabil Y. Lhachemi, Ion Garate
The phonon magnetochiral effect consists of a nonreciprocity in the velocity or attenuation of acoustic waves when they propagate parallel and antiparallel to an external magnetic…
