Activity and Competing Length Scales in an Anomalous Core-Softened Fluid
Davi Felipe Kray Silva, Thiago Puccinelli, Walas Silva-Oliveira +2
The interplay between activity and competing interaction length scales remains largely unexplored, despite its relevance to many soft and biological systems. Here, we study Active…
Stability and Dynamics of Sn-based Halide Perovskites: Insights from MACE-MP-0 and Molecular Dynamics Simulations
Thiago Puccinelli, Lucas Martin Farigliano, Gustavo Martini Dalpian
Tin-based halide perovskites have emerged as promising lead-free alternatives for optoelectronic applications, yet their structural stability and phase behavior at finite temperatu…
Order-Disorder Transitions and Thermal Pathways in Frustrated 2D Colloidal Crystals
Alexandre Vargas, Thiago Puccinelli, José Rafael Bordin
We employ extensive NPT molecular dynamics simulations to explore the thermal transitions of two-dimensional colloidal crystals interacting via a core-softened potential with compe…
Competing Length Scales and Symmetry Frustration Govern Non-Universal Melting in 2D Core-softened Colloidal Crystals
Thiago Puccinelli, Alexandre V. Ilha, José Rafael Bordin
We investigate the melting behavior of two-dimensional colloidal crystals stabilized by a core-softened potential featuring two competing interaction length scales. Using molecular…
