Multiloop calculations with Implicit Regularization in massless theories
E. W. Dias, A. P. Baeta Scarpelli, L. C. T. Brito +1
We establish a systematic way to calculate multiloop amplitudes of infrared safe massless models with Implicit Regularization (IR), with a direct cancelation of the fictitious mass…
Complex evolution of the electronic structure from polycrystalline to monocrystalline graphene: generation of a new Dirac point
Joice da Silva Araujo, R. W. Nunes
First principles calculations, employed to address the properties of polycrystalline graphene, indicate that the electronic structure of tilt grain boundaries in this system displa…
Extreme nonlocality with one photon
Libby Heaney, Adan Cabello, Marcelo F. Santos +1
Quantum nonlocality is typically assigned to systems of two or more well separated particles, but nonlocality can also exist in systems consisting of just a single particle, when o…
Decoherence in a double-slit quantum eraser
F. A. Torres-Ruiz, G. Lima, A. Delgado +2
We study and experimentally implement a double-slit quantum eraser in the presence of a controlled decoherence mechanism. A two-photon state, produced in a spontaneous parametric d…
A Thermodynamic Formalism for density matrices in Quantum Information
A. Baraviera, C. F. Lardizabal, Artur O. Lopes +1
We consider new concepts of entropy and pressure for stationary systems acting on density matrices which generalize the usual ones in Ergodic Theory. Part of our work is to justify…
Electron Transport in Disordered Graphene Nanoribbons
Melinda Y. Han, Juliana C. Brant, Philip Kim
We report an electron transport study of lithographically fabricated graphene nanoribbons of various widths and lengths at different temperatures. At the charge neutrality point, a…
