Magnetization profile for impurities in graphene nanoribbons
S. R. Power, V. M. de Menezes, S. B. Fagan +1
The magnetic properties of graphene-related materials and in particular the spin-polarised edge states predicted for pristine graphene nanoribbons (GNRs) with certain edge geometri…
Impurity segregation in graphene nanoribbons
S. R. Power, V. M. de Menezes, S. B. Fagan +1
The electronic properties of low-dimensional materials can be engineered by doping, but in the case of graphene nanoribbons (GNR) the proximity of two symmetry-breaking edges intro…
The Arrow Calculus as a Quantum Programming Language
Juliana Kaizer Vizzotto, Andre Rauber Du Bois, Amr Sabry
We express quantum computations (with measurements) using the arrow calculus extended with monadic constructions. This framework expresses quantum programming using well-understood…
Achernar: Rapid Polarization Variability as Evidence of Photospheric and Circumstellar Activity
A. C. Carciofi, A. M. Magalhães, N. V. Leister +2
We present the results of a high accuracy () polarization monitoring of the Be Star Achernar that was carried out between July 7th and November 5th, 2006. Our resu…
Integral equations of scattering in one dimension
Vania E. Barlette, Marcelo M. Leite, Sadhan K. Adhikari
A self-contained discussion of integral equations of scattering is presented in the case of centrally-symmetric potentials in one dimension, which will facilitate the understanding…
Anomalies in Ward Identities for Three-Point Functions Revisited
O. A. Battistel, O. L. Battistel
A general calculational method is applied to investigate symmetry relations among divergent amplitudes in a free fermion model. A very traditional work on this subject is revisited…
