First-principles real-space study of electronic and optical excitations in rutile TiO2 nanocrystals.
(American Physical Society, 2014-10-17)
We model rutile titanium dioxide nanocrystals (NCs) up to ∼1.5 nm in size to study the effects of quantum confinement on their electronic and optical properties. Ionization potentials (IPs) and electron affinities (EAs) are ...
Redux on “When is the top quark a parton?”
(American Physical Society, 2014-07-01)
If a new heavy particle ϕ is produced in association with the top quark in a hadron collider, the production cross section exhibits a collinear singularity of the form logðmϕ=mtÞ, which can be resummed by introducing a ...
Direct observation of the structural and electronic changes of Li2MnO3 during electron irradiation
(American Institute of Physics, 2014)
This study focuses on the effects of electron beam induced irradiation to the layered oxide Li2MnO3. Aberration-corrected scanning transmission electron microscopy and electron energy loss spectroscopy are used to ...
Supernova bounds on Weinberg’s Goldstone bosons
(American Physical Society, 2014-10-16)
Recently, Weinberg proposed a scenario where Goldstone bosons may be masquerading as fractional cosmic neutrinos. We calculate the energy loss rates through the emission of these Goldstone bosons in a postcollapse supernova ...
Charge-carrier transport and recombination in heteroepitaxial CdTe
(American Institute of Physics, 2014-12)
We analyze charge-carrier dynamics using time-resolved spectroscopy and varying epitaxial CdTe thickness in undoped heteroepitaxial CdTe/ZnTe/Si. By employing one-photon and nonlinear two-photon excitation, we assess ...
Terreur et théologie: Paulhan, Scarry, Novarina
(Armand Colin/LAROUSSE, 2014-12)
Valere Novarina occupies an unusual position with respect to Jean Paulhan and his concept of literary "terror". On the one hand, the aim of his poetics is innovative and iconoclastic; on the other, he venerates a rhetorical ...
