First principles calculations of electric-field-driven topological phase transitions in silicene, germanene and stanene
Julián Antonio Villarreal Murúa, Pablo Roura-Bas, Javier Daniel Fuhr +1
The emergence of two-dimensional topological materials, particularly the group-14 monolayers known as silicene, germanene, and stanene has opened promising pathways for next-genera…
Optimisation and Precision Tuning of Localised Surface Plasmon Resonance in AuFON Systems
Luis Alfonso Guerra Hernández, Osmar Gil Salas, Jorge Enrique Rueda Parada +2
Metal film on nanosphere (MFON) plasmonic systems have emerged as nanostructures with useful properties for molecular detection. This work presents the optimisation and discussion…
Logistic dynamics of small populations with demographic stochasticity
Lucas M. Brugevin, Damián H. Zanette
We study an ecology-inspired model for a population of bounded size, whose dynamics is governed by random birth, death, and immigration events. Stochastic fluctuations in the numbe…
Data-Driven Modelling to predict forest fire spread in the Patagonian region in Argentina
Lucas Becerra, Monica Malen Denham, Alejandro B. Kolton +1
Wildfires are among the most severe disturbances affecting forest ecosystems, with over 50,000 hectares burned in Patagonia, Argentina, during 2025 alone. This study implements a R…
Effect of spin-orbit coupling on spin and orbital ordering in SrCrO,
Cristian Fanjul, A. A. Aligia
We incorporate spin-orbit coupling (SOC) into effective Kugel-Khomskii models for the and members of the Ruddlesden-Popper series SrCrO. These mode…
Can Light Cross a Singularity? Exact Solutions from Analogue Gravity
Juan Manuel Paez, Franco Fiorini, Santiago M. Hernández
Using a simple spacetime hosting a strong curvature naked singularity, we employ an analogue gravity model to study electromagnetic fields in this background. We find exact solutio…
