Local roughness exponent in the nonlinear molecular-beam-epitaxy universality class in one-dimension
Edwin E. Mozo Luis, Thiago A. de Assis, Silvio C. Ferreira +1
We report local roughness exponents, , for three interface growth models in one dimension which are believed to belong the non-linear molecular-beam-epitaxy (nMBE)…
Controlling optical memory effects in disordered media with coated metamaterials
Tiago J. Arruda, Alexandre S. Martinez, Felipe A. Pinheiro
Most applications of memory effects in disordered optical media, such as the tilt-tilt and shift-shift spatial correlations, have focused on imaging through and inside biological t…
Hermite-Gaussian model for quantum states
Marcelo Losada, Ignacio S. Gomez, Federico Holik
In order to characterize quantum states within the context of information geometry, we propose a generalization of the Gaussian model, which we called the Hermite-Gaussian model. W…
A three-state model with competing antiferromagnetic and pairing interactions
Sergio A. Cannas, Daniel A. Stariolo
Motivated by the rich phase diagram of the high temperature superconductors, we introduce a toy model with three state variables which can be interpreted as two state particles and…
Intraday Seasonalities and Nonstationarity of Trading Volume in Financial Markets: Individual and Cross-Sectional Features
Michelle B Graczyk, Silvio M D Queirós
We study the intraday behaviour of the statistical moments of the trading volume of the blue chip equities that composed the Dow Jones Industrial Average index between 2003 and 201…
Scaling properties of d-dimensional complex networks
Samuraí Brito, Thiago C. Nunes, Luciano R. da Silva +1
The area of networks is very interdisciplinary and exhibits many applications in several fields of science. Nevertheless, there are few studies focusing on geographically located $…
Optimal diffusion in ecological dynamics with Allee effect in a metapopulation
Marcelo A. Pires, Sílvio M. Duarte Queirós
How diffusion impacts on ecological dynamics under the Allee effect and spatial constraints? That is the question we address. Employing a microscopic minimal model in a metapopulat…
Characterizing complex networks using Entropy-degree diagrams: unveiling changes in functional brain connectivity induced by Ayahuasca
A. Viol, Fernanda Palhano-Fontes, Heloisa Onias +3
Open problems abound in the theory of complex networks, which has found successful application to diverse fields of science. With the aim of further advancing the understanding of…
Electromagnetic energy within coated spheres containing dispersive metamaterials
Tiago J. Arruda, Felipe A. Pinheiro, Alexandre S. Martinez
An exact expression is derived for the time-averaged electromagnetic energy within a magneto-dielectric coated sphere, which is irradiated by a plane and time-harmonic electromagne…
Validity and Failure of the Boltzmann Weight
Leonardo J. L. Cirto, Antonio Rodríguez, Fernando D. Nobre +1
The dynamics and thermostatistics of a classical inertial XY model, characterized by long-range interactions, are investigated on -dimensional lattices ( and 3), through…
Activation thresholds in epidemic spreading with motile infectious agents on scale-free networks
Diogo H. Silva, Silvio C. Ferreira
We investigate a fermionic susceptible-infected-susceptible model with mobility of infected individuals on uncorrelated scale-free networks with power-law degree distributions $P (…
Threshold -voter model
Allan R. Vieira, Celia Anteneodo
We introduce the threshold -voter opinion dynamics where an agent, facing a binary choice, can change its mind when at least amongst neighbors share the opposite opini…
Overdamped dynamics of particles with repulsive power-law interactions
André A. Moreira, César M. Vieira, Humberto A. Carmona +2
We investigate the dynamics of overdamped -dimensional systems of particles repulsively interacting through short-ranged power-law potentials, . We sho…
Eden model with nonlocal growth rules and the kinetic roughening in biological systems
Silvia N. Santalla, Silvio C. Ferreira
We investigate an off-lattice Eden model where the growth of new cells is performed with a probability dependent on the availability of resources coming externally towards the grow…
Robustness and fragility of the susceptible-infected-susceptible epidemic models on complex networks
Wesley Cota, Angélica S. Mata, Silvio C. Ferreira
We analyze two alterations of the standard susceptible-infected-susceptible (SIS) dynamics that preserve the central properties of spontaneous healing and infection capacity of a v…
A position-dependent mass harmonic oscillator and deformed space
Bruno G. da Costa, Ernesto P. Borges
We consider canonically conjugated generalized space and linear momentum operators and in quantum mechanics, associated to a generalized translation operat…
Cooperation risk and Nash equilibrium: quantitative description for realistic players
G. M. Nakamura, G. S. Contesini, A. S. Martinez
The emergence of cooperation figures among the main goal of game theory in competitive-cooperative environments. Potential games have long been hinted as viable alternatives to stu…
Griffiths phases in infinite-dimensional, non-hierarchical modular networks
Wesley Cota, Géza Ódor, Silvio C. Ferreira
Griffiths phases (GPs), generated by the heterogeneities on modular networks, have recently been suggested to provide a mechanism, rid of fine parameter tuning, to explain the crit…
