Polarization inhibits the phase transition of Axelrod's model
Carlos Gracia-Lázaro, Edgardo Brigatti, Alexis R. Hernández +1
We study the effect of polarization in Axelrod's model of cultural dissemination. This is done through the introduction of a cultural feature that takes only two values, while the…
Modeling how social network algorithms can influence opinion polarization
Henrique F. de Arruda, Felipe M. Cardoso, Guilherme F. de Arruda +3
Among different aspects of social networks, dynamics have been proposed to simulate how opinions can be transmitted. In this study, we propose a model that simulates the communicat…
Investigating transverse Hall conductances using two-terminal setups
Alexis R. Hernández, Leandro R. F. Lima
In this paper we present a method to numerically study transverse Hall conductances using a two-terminal setup. Using nonlinear transport concepts we find that the Hall voltage dep…
Gauge fields in graphene with nonuniform elastic deformations: A quantum field theory approach
Enrique Arias, Alexis R. Hernández, Caio Lewenkopf
We investigate the low energy continuum limit theory for electrons in a graphene sheet under strain. We use the quantum field theory in curved spaces to analyze the effect of the s…
Finite-difference method for transport of two-dimensional massless Dirac fermions in a ribbon geometry
Alexis R. Hernández, Caio H. Lewenkopf
We present a numerical method to compute the Landauer conductance of noninteracting two-dimensional massless Dirac fermions in disordered systems. The method allows for the introdu…
Non-adiabatic Electron Pumping through Interacting Quantum Dots
Alexander Croy, Ulf Saalmann, Alexis R. Hernández +1
We study non-adiabatic charge pumping through single-level quantum dots taking into account Coulomb interactions. We show how a truncated set of equations of motion can be propagat…
