Characterizing network topology using first-passage analysis
M. S. Chaves, T. G. Mattos, A. P. F. Atman
Understanding the topological characteristics of complex networks and how they affect navigability is one of the most important goals in science today, as it plays a central role i…
Moderate death rates can be beneficial for the evolution of cooperation
Elton Júnior. S, Marco A. Amaral, Lucas Wardil
Spatial structure is one of the simplest and most studied ecological factors that affect the evolution of cooperation. It has been shown that spatial reciprocity promotes cooperati…
The Multiplex Efficiency Index: unveiling the Brazilian Air Transportation Multiplex Network -- BATMN
Izabela M. Oliveira, Laura C. Carpi, A. P. F. Atman
Modern society is increasingly massively connected, reflecting an omnipresent tendency to organize social, economic, and technological structures in complex networks. Recently, wit…
Multirange Ising model on the square lattice
Charles S. do Amaral, B. N. B. de Lima, Ronald Dickman +1
We study the Ising model on and show, via numerical simulation, that allowing interactions between spins separated by distances and (two ranges), the criti…
The VISCACHA survey -- deep and resolved photometry of star clusters in the Magellanic Clouds
Bruno Dias, Francisco Maia, Leandro Kerber +24
The VISCACHA (VIsible Soar photometry of star Clusters in tApii and Coxi HuguA\footnote{LMC and SMC names in the Tupi-Guarani language spoken by native people in Brazil}) Survey is…
Role of vector channel in different classes of (non) magnetized neutron stars
Luiz L. Lopes, Debora P. Menezes
We study how the magnetic field and non-standard vector channels affect hadronic, quarkionic and hybrid stars. In the hadronic phase, we use the QHD model, within its standard $σωρ…
Nearly coeval intermediate-age Milky Way star clusters at very different dynamics evolutionary stages
Andrés E. Piatti, Mateus S. Angelo, Wilton S. Dias
We report astrophysical properties of 12 Milky Way open clusters located beyond the circle around the Sun where the number of catalogued open clusters is thought to be statisticall…
Characterizing dynamical stages of open clusters located in the Sagittarius spiral arm
M. S. Angelo, A. E. Piatti, W. S. Dias +1
The study of dynamical properties of Galactic open clusters is a fundamental prerequisite for the comprehension of their dissolution processes. In this work, we characterized 12 op…
Gravitational Wave Signatures of Highly Magnetized Neutron Stars
Cesar V. Flores, Luiz L. Lopes, Luis B. Castro +1
Motivated by the recent gravitational wave detection by the LIGO-VIRGO observatories, we study the Love number and dimensionless tidal polarizability of highly magnetized stars. We…
Investigating dynamical properties of evolved Galactic open clusters
M. S. Angelo, J. F. C. Santos, W. J. B. Corradi +1
The stellar content of Galactic open clusters is gradually depleted during their evolution as a result of internal relaxation and external interactions. The final residues of the e…
The VISCACHA survey - I. Overview and First Results
Francisco F. S. Maia, Bruno Dias, João F. C. Santos +15
The VISCACHA (VIsible Soar photometry of star Clusters in tApii and Coxi HuguA) Survey is an ongoing project based on deep photometric observations of Magellanic Cloud star cluster…
Jarzynski equality for superconducting optical cavities: an alternative path to determine Helmholtz free energy
Josiane Oliveira Rezende de Paula, J. G. Peixoto de Faria, J. G. G. de Oliveira +2
A superconducting cavity model was proposed as a way to experimentally investigate the work performed in a quantum system. We found a simple mathematical relationship between the f…
