Parrondo's effects with aperiodic protocols
Marcelo A. Pires, Erveton P. Pinto, Rone N. da Silva +1
In this work, we study the effectiveness of employing archetypal aperiodic sequencing -- namely Fibonacci, Thue-Morse, and Rudin-Shapiro -- on the Parrondian effect. From a capital…
Quantum walks with spatiotemporal fractal disorder
Marcelo A. Pires, Caio B. Naves, Diogo O. Soares-Pinto +1
We investigate the transport and entanglement properties exhibited by quantum walks with coin operators concatenated in a space-time fractal structure. Inspired by recent developme…
Quantum walks in two dimensions: controlling directional spreading with entangling coins and tunable disordered step operator
Caio B. Naves, Marcelo A. Pires, Diogo O. Soares-Pinto +1
We study a 2-D disordered time-discrete quantum walk based on 1-D `generalized elephant quantum walk' where an entangling coin operator is assumed and which paves the way to a new…
Enhancing entanglement with the generalized elephant quantum walk from localized and delocalized states
Caio B. Naves, Marcelo A. Pires, Diogo O. Soares-Pinto +1
Recently, it was introduced a generalization of a nonstandard step operator named the elephant quantum walk (EQW). With proper statistical distribution for the steps, that generali…
Diffusion plays an unusual role in ecological quasi-neutral competition in metapopulations
Marcelo A. Pires, Nuno Crokidakis, Silvio M. Duarte Queirós
We investigate the phenomenology emerging from a 2-species dynamics under the scenario of a quasi-neutral competition within a metapopulation framework. We employ stochastic and de…
Negative correlations can play a positive role in disordered quantum walks
Marcelo A. Pires, Sílvio M. Duarte Queirós
We investigate the emerging properties of quantum walks with temporal disorder engineered from a binary Markov chain with tailored correlation, , and disorder strength, . We…
Hysteresis and disorder-induced order in continuous kinetic-like opinion dynamics in complex networks
A. L. Oestereich, M. A. Pires, S. M. Duarte Queirós +1
In this work we tackle a kinetic-like model of opinions dynamics in a networked population endued with a quenched plurality and polarization. Additionally, we consider pairwise int…
Quantum walks with sequential aperiodic jumps
Marcelo A. Pires, Sílvio M. Duarte Queirós
We analyze a set of discrete-time quantum walks for which the displacements on a chain follow binary aperiodic jumps according to three paradigmatic sequences: Fibonacci, Thue-Mors…
