Optimal Number of Faces for Fast Self-Folding Kirigami
H. P. M. Melo, C. S. Dias, N. A. M. Araujo
We study the spontaneous folding of a 2D template of microscopic panels into a 3D pyramid, driven by thermal fluctuations. Combining numerical simulations and analytical calculatio…

Mechanical equilibrium of aggregates of dielectric spheres
A. F. V. Matias, T. Shinbrot, N. A. M. Araujo
Industrial as well as natural aggregation of fine particles is believed to be associated with electrostatics. Yet like charges repel, so it is unclear how similarly treated particl…

The symbiotic contact process: phase transitions, hysteresis cycles, and bistability
C. I. N. Sampaio Filho, T. B. dos Santos, N. A. M. Araújo +3
We performed Monte Carlo simulations of the symbiotic contact process on different spatial dimensions (). On the complete and random graphs (infinite dimension), we observe hyst…
