Discrete-time quantum walks as fermions of lattice gauge theory

Pablo Arnault, Armando Pérez, Pablo Arrighi +1

It is shown that discrete-time quantum walks can be used to digitize, i.e., to time discretize fermionic models of continuous-time lattice gauge theory. The resulting discrete-time…

Giant catalytic effect of altruists in Schelling's segregation model

P. Jensen, T. Matreux, J. Cambe +2

We study the effect of introducing altruistic agents in a Schelling-like model of residential segregation. We find that even an infinitesimal proportion of altruists has dramatic c…

The Dirac equation as a quantum walk over the honeycomb and triangular lattices

Pablo Arrighi, Giuseppe Di Molfetta, Iván Márquez-Martín +1

A discrete-time Quantum Walk (QW) is essentially an operator driving the evolution of a single particle on the lattice, through local unitaries. Some QWs admit a continuum limit, l…

A gauge-invariant reversible cellular automaton

Pablo Arrighi, Giuseppe Di Molfetta, Nathanaël Eon

Gauge-invariance is a fundamental concept in physics---known to provide the mathematical justification for all four fundamental forces. In this paper, we provide discrete counterpa…

Coexistence of several currencies in presence of increasing returns to adoption

Alex Lamarche-Perrin, André Orléan, Pablo Jensen

We present a simplistic model of the competition between different currencies. Each individual is free to choose the currency that minimizes his transaction costs, which arise when…
