Decoding Decentralized Finance Transactions through Ego Network Motif Mining

Natkamon Tovanich, Célestin Coquidé, Rémy Cazabet

Decentralized Finance (DeFi) is increasingly studied and adopted for its potential to provide accessible and transparent financial services. Analyzing how investors use DeFi is imp…

A toy model for approaching volcanic plumbing systems as complex systems

Remy Cazabet, Catherine Annen, Jean-Francois Moyen +1

Magmas form at depth, move upwards and evolve chemically through a combination of processes. Magmatic processes are investigated by means of fieldwork combined with geophysics, geo…

Temporal and Geographical Analysis of Real Economic Activities in the Bitcoin Blockchain

Rafael Ramos Tubino, Remy Cazabet, Natkamon Tovanich +1

We study the real economic activity in the Bitcoin blockchain that involves transactions from/to retail users rather than between organizations such as marketplaces, exchanges, or…

Quantum simulation of quantum relativistic diffusion via quantum walks

Pablo Arnault, Adrian Macquet, Andreu Anglés-Castillo +6

Two models are first presented, of one-dimensional discrete-time quantum walk (DTQW) with temporal noise on the internal degree of freedom (i.e., the coin): (i) a model with both a…

Non-Abelian Gauge-Invariant Cellular Automata

Pablo Arrighi, Giuseppe Di Molfetta, Nathanaël Eon

Gauge-invariance is a mathematical concept that has profound implications in Physics---as it provides the justification of the fundamental interactions. It was recently adapted to…

The Grover search as a naturally occurring phenomenon

Mathieu Roget, Stéphane Guillet, Pablo Arrighi +1

We provide first evidence that under certain conditions, 1/2-spin fermions may naturally behave like a Grover search, looking for topological defects in a material. The theoretical…

Graph-based era segmentation of international financial integration

Cécile Bastidon, Antoine Parent, Pablo Jensen +2

Assessing world-wide financial integration constitutes a recurrent challenge in macroeconometrics, often addressed by visual inspections searching for data patterns. Econophysics l…

An overview of Quantum Cellular Automata

Pablo Arrighi

Quantum cellular automata consist in arrays of identical finite-dimensional quantum systems, evolving in discrete-time steps by iterating a unitary operator G. Moreover the global…

The politics of physicists social models

Pablo Jensen

I give an overview of the topic of this special issue, the applications of (statistical) physics to social sciences at large. I discuss several examples of simple social models put…

In social complex systems, the whole can be more or less than (the sum of) the parts

Eric Bertin, Pablo Jensen

We discuss in a statistical physics framework the idea that ``the whole is less than the parts'', as sometimes advocated by sociologists in view of the intrinsic complexity of huma…

Reentrant phase transitions in threshold driven contagion on multiplex networks

Samuel Unicomb, Gerardo Iñiguez, János Kertész +1

Models of threshold driven contagion explain the cascading spread of information, behavior, systemic risk, and epidemics on social, financial and biological networks. At odds with…

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…

Threshold driven contagion on weighted networks

Samuel Unicomb, Gerardo Iñiguez, Márton Karsai

Weighted networks capture the structure of complex systems where interaction strength is meaningful. This information is essential to a large number of processes, such as threshold…

Burstiness and tie reinforcement in time varying social networks

Enrico Ubaldi, Alessandro Vezzani, Marton Karsai +2

We introduce a time-varying network model accounting for burstiness and tie reinforcement observed in social networks. The analytical solution indicates a non-trivial phase diagram…

Quantum Causal Graph Dynamics

Pablo Arrighi, Simon Martiel

Consider a graph having quantum systems lying at each node. Suppose that the whole thing evolves in discrete time steps, according to a global, unitary causal operator. By causal w…

Detecting global bridges in networks

Pablo Jensen, Matteo Morini, Marton Karsai +6

The identification of nodes occupying important positions in a network structure is crucial for the understanding of the associated real-world system. Usually, betweenness centrali…

User-based representation of time-resolved multimodal public transportation networks

Laura Alessandretti, Márton Karsai, Laetitia Gauvin

Multimodal transportation systems can be represented as time-resolved multilayer networks where different transportation modes connecting the same set of nodes are associated to di…
