🚨🚨 ¡Atención! 🚨🚨

La IV edición del congreso FisEs Joven, un congreso online dedicado a jóvenes investigadores e investigadoras en física estadística, comienza hoy!

Programa: fisesjoven26.gefenol.es

Here's another new article in @commsphys.nature.com, this time about higher-order interactions!

We demonstrate that sparse group-based interactions, which are commonplace in today's digital societies, promote social polarisation.

This is especially relevant given the current tense situation.

No os perdáis el FisEs Joven! El mejor congreso para conocer la investigación de los jóvenes investigadores 🏆

1/6 And another article out in @commsphys.nature.com

Sparse group interactions polarize…but dense group interactions moderate!!

Polarization emerges as a structural effect of how groups are organized: www.nature.com/articles/s42...

I'm really happy to see this article being published!

I find it very intriguing that the topology of genotype networks, which reflects the exploration of the antigenic space, can alone be enough to explain seasonality in epidemic trajectories.

1/7 🚨 New article out in @commsphys.nature.com

We show that viral 🦠 evolution is best captured through complex genotype networks, whose topology alone can drive oscillatory endemic dynamics and epidemic variability:

Really happy to see this out in PRX Life! There you can find an eco-evolutionary framework integrating the evolution of viral infectiousness and antigenic features. While the former determines contagion events among hosts, the latter tells us how quickly viruses can escape population immunity 1/4👇

Explosive adoption of corrupt behaviors in social systems with higher-order interactions Human behaviors in social systems are often shaped by group pressure and collective norms, especially since the rise of social media platforms. However, in the

Social polarization promoted by sparse higher-order interactions Many social interactions are group-based, yet their role in social polarization remains largely unexplored. To bridge this gap here we introduce a higher-order framework that takes into account both g...

Asado grupal para cerrar el curso académico. A pesar del calor a la brasa sabe mejor!!!

We continue the Friday morning at #Fises2025 with five contributed talks by Philipp Strasberg, Álvaro Rodríguez, Santiago Lamata‑Otín, Alfredo Crespo, and Martín Saavedra, covering a variety of topics from higher‑order networks to climate modelling. #StatisticalPhysics #ComplexSystems #Biophysics

Genotype networks drive oscillating endemicity and epidemic trajectories in viral evolution Rapidly evolving viruses use antigenic drift as a key mechanism to evade host immunity and persist in real populations. While traditional models of antigenic drift and epidemic spread rely on low-dime...
