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…
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…
Multiple transitions between normal and hyperballistic diffusion in quantum walks with time-dependent jumps
Marcelo A. Pires, Giuseppe Di Molfetta, Sílvio M. Duarte Queirós
We extend to the gamut of functional forms of the probability distribution of the time-dependent step-length a previous model dubbed Elephant Quantum Walk, which considers a unifor…
