A soliton with a long-range tail
André Amado, Azadeh Mohammadi
We propose an analytically solvable sextic potential model with non-trivial soliton solutions connecting the trivial vacua. The model does not respect parity symmetry, and like $ϕ^…
Agent-based models of collective intelligence
Sandro M. Reia, André C. Amado, José F. Fontanari
Collective or group intelligence is manifested in the fact that a team of cooperating agents can solve problems more efficiently than when those agents work in isolation. Although…
Quantum corrections to the generalized Proca theory via a matter field
André Amado, Zahra Haghani, Azadeh Mohammadi +1
We study the quantum corrections to the generalized Proca theory via matter loops. We consider two types of interactions, linear and nonlinear in the vector field. Calculating the…
The influence of the composition of tradeoffs on the generation of differentiated cells
André Amado, Paulo R. A. Campos
We study the emergence of cell differentiation under the assumption of the existence of a given number of tradeoffs between genes encoding different functions. In the model the via…
Coexistence of competing metabolic pathways in well-mixed populations
Lenin Fernández, André Amado, Fernando Fagundes Ferreira +1
Understanding why strains with different metabolic pathways that compete for a single limiting resource coexist is a challenging issue within a theoretical perspective. Previous in…
Competing metabolic strategies in a multilevel selection model
André Amado, Lenin Fernández, Weini Huang +2
The interplay between energy efficiency and evolutionary mechanisms is addressed. One important question is how evolutionary mechanisms can select for the optimised usage of energy…
Coupled fermion-kink system in Jackiw-Rebbi model
André Amado, Azadeh Mohammadi
In this paper we study Jackiw-Rebbi model, in which a massless fermion is coupled to the kink of theory through a Yukawa interaction. In the original Jackiw-Rebbi model the…
Flux tube widening in compact U (1) lattice gauge theory computed at T < Tc with the multilevel method and GPUs
A. Amado, N. Cardoso, P. Bicudo
We utilize Polyakov loop correlations to study d=3+1 compact U (1) flux tubes and the static electron-positron potential in lattice gauge theory. With the plaquette field operator,…
Study of compact U(1) flux tubes in 3+1 dimensions in lattice gauge theory using GPU's
André Amado, Nuno Cardoso, Marco Cardoso +1
We utilize Polyakov loop correlations to study (3+1)D compact U(1) flux tubes and the static electron-positron potential in lattice gauge theory. By using field operators it is pos…
