Structural and dynamic anomalous properties of TIP4P/2005 water at extreme pressures
José Martín-Roca, Alberto Zaragoza, Frédéric Caupin +1
Water shows numerous thermodynamic, dynamic, and structural anomalies. Recent experiments [Eichler et al. Phys. Rev. Lett. 134, 134101 (2025)], based on measurements of shear and b…
Confinement-induced collective motion in suspensions of run-and-tumble particles
José Martín-Roca, Daniel Escobar Ortiz, Chantal Valeriani +1
Collective motion is ubiquitous in active systems at all length and time scales. The mechanisms behind such collective motion usually are alignment interactions between active part…
MIPS is a Maxwell fluid with an extended and non-monotonic crossover
José Martín-Roca, Chantal Valeriani, Kristian Thijssen +2
Understanding the mechanical properties of active suspensions is crucial for their potential applications in materials engineering. Among the various phenomena in active matter tha…
Active Polymer Behavior in Two Dimensions: A Comparative Analysis of Tangential and Push-Pull Models
Giulia Janzen, Juan Pablo Miranda, José Martín-Roca +4
In this work, we compare the structural and dynamic behavior of active filaments in two dimensions using tangential and push-pull models, including a variant with passive end monom…
