Gamma-Ray Burst detection prospects for next generation ground-based VHE facilities
G. La Mura, U. Barres de Almeida, R. Conceição +6
Gamma-ray Bursts (GRB) were discovered by satellite-based detectors as powerful sources of transient -ray emission. The Fermi satellite detected an increasing number of these ev…
At the verge of topology: vacancy-driven quantum spin Hall in trivial insulators
F. Crasto de Lima, Adalberto Fazzio
Vacancies in materials structure -- lowering its atomic density -- take the system closer to the atomic limit, to which all systems are topologically trivial. Here we show a mechan…
Amorphous BiSe structural, electronic, and topological nature by first-principles
Bruno Focassio, Gabriel R. Schleder, F. Crasto de Lima +2
Crystalline is one of the most explored three-dimensional topological insulator, with a energy gap making it promising for applications. Its amorphous…
An introduction to fractional calculus: Numerical methods and application to HF dielectric response
André Persechino
The aim of this work is to introduce the main concepts of Fractional Calculus, followed by one of its application to classical electrodynamics, illustrating how non-locality can be…
Machine learning for materials discovery: two-dimensional topological insulators
Gabriel R. Schleder, Bruno Focassio, Adalberto Fazzio
One of the main goals and challenges of materials discovery is to find the best candidates for each interest property or application. Machine learning rises in this context to effi…
Machine learning of microscopic ingredients for graphene oxide/cellulose interaction
Romana Petry, Gustavo Silvestre, Bruno Focassio +3
Understanding the role of microscopic attributes in nanocomposites allows for a controlled and, therefore, acceleration in experimental system designs. In this work, we extracted t…
Enhancing the effective critical current density in a Nb superconducting thin film by cooling in an inhomogeneous magnetic field
D. A. D. Chaves, I. M. de Araújo, D. Carmo +7
Quantitative magneto-optical imaging of a type-II superconductor thin film cooled under zero, homogeneous, and inhomogeneous applied magnetic fields, indicates that the latter proc…
Conformational analysis of tannic acid: environment effects in electronic and reactivity properties
Romana Petry, Bruno Focassio, Gabriel R. Schleder +2
Polyphenols are natural molecules of crucial importance in many applications, of which tannic acid (TA) is one of the most abundant and established. Most high-value applications re…
Entropy bound in Einstein-Born-Infeld black holes
F. T. Falciano, M. L. Peñafiel, J. C. Fabris
We study the validity of Bekenstein's entropy bound for a charged black hole in the context of nonlinear electrodynamics. Bekenstein's inequalities are commonly understood as unive…
Measurement of critical current flow and connectivity in systems of joined square superconducting plates
F. Colauto, D. Carmo, A. M. H. de Andrade +4
A method to measure the electrical connectivity between square superconducting plates joined by weak link interfaces is presented. It is based on observation of lines where the flo…
The 2021 Quantum Materials Roadmap
Feliciano Giustino, Jin Hong Lee, Felix Trier +26
In recent years, the notion of Quantum Materials has emerged as a powerful unifying concept across diverse fields of science and engineering, from condensed-matter and cold atom ph…
Bandgap evolution in nanographene assemblies
F. Crasto de Lima, A. Fazzio
Recently cycloarene has been experimentally obtained in a self-assembled structure, forming graphene-like monoatomic layered systems. Here, we establish the bandgap engineering/pre…
