Multiferroic double perovskites: Opportunities, Issues and Challenges
M. P. Singh, K. D. Truong, S. Jandl +1
Despite the great technological and scientific importance, a well-controlled coupled behavior in magnetoelectric multiferroic materials at room temperature remains challenging. We…
Analysis of the excited-state absorption spectral bandshape of oligofluorenes
Sophia C. Hayes, Carlos Silva
We present ultrafast transient absorption spectra of two oligofluorene derivatives in dilute solution. These spectra display clear vibronic structure, which we analyze rigorously u…
Doping of C-induced electronic states in BN nanopeapods
Vladimir Timoshevskii, Michel Cote
We report the results of \textit{ab initio} simulations of the electronic properties of a chain of C molecules encapsulated in a boron nitride nanotube - so called BN-nanope…
Large electronic bandwidth in solution-processable pyrene crystals: The role of close-packed crystal structure
Francoise Provencher, Jean-Frederic Laprade, Gabrielle Simard +3
We examine the interdependence of structural and electronic properties of two substituted pyrene crystals by means of combined spectroscopic probes and density-functional theory ca…
Influence of Ni/Mn cation order on the spin-phonon coupling in multifunctional La2NiMnO6 epitaxial films by polarized Raman spectroscopy
K. D. Truong, M. P. Singh, S. Jandl +1
We report the influence of Ni/Mn ordering on the spin-phonon coupling in multifunctional La2NiMnO6. Three types of films with different levels of structural order, including long-r…
Carrier thermal escape in families of InAs/InP self-assembled quantum dots
Guillaume Gélinas, Ali Lanacer, Richard Leonelli +3
We investigate the thermal quenching of the multimodal photoluminescence from InAs/InP (001) self-assembled quantum dots. The temperature evolution of the photoluminescence spectra…
Charge-transfer excitons in strongly coupled organic semiconductors
Jean-Francois Glowe, Mathieu Perrin, David Beljonne +3
Time-resolved and temperature-dependent photoluminescence measurements on one-dimensional sexithiophene lattices reveal intrinsic branching of photoexcitations to two distinct spec…
High-energy excitonic effects in graphite and graphene
Paolo E. Trevisanutto, Markus Holzmann, Michel Cote +1
We present ab initio many-body calculations of the optical absorption in bulk graphite, graphene and bilayer of graphene. Electron-hole interaction is included solving the Bethe-Sa…
Microwave dielectric study of spin-Peierls and charge ordering transitions in (TMTTF)PF salts
Alexandre Langlois, Mario Poirier, Claude Bourbonnais +3
We report a study of the 16.5 GHz dielectric function of hydrogenated and deuterated organic salts (TMTTF)PF. The temperature behavior of the dielectric function is consist…
Progress and perspectives on the electron-doped cuprates
N. P. Armitage, P. Fournier, R. L. Greene
Although the vast majority of high- cuprate superconductors are hole-doped, a small family of electron-doped compounds exists. Under investigated until recently, there has bee…
Ultrastrong coupling regime of cavity QED with phase-biased flux qubits
J. Bourassa, J. M. Gambetta, A. A. Abdumalikov +3
We theoretically study a circuit QED architecture based on a superconducting flux qubit directly coupled to the center conductor of a coplanar waveguide transmission-line resonator…
