Tricritical behavior in epidemic dynamics with vaccination
Marcelo A. Pires, Cesar I. N. Sampaio Filho, Hans J. Herrmann +1
We scrutinize the phenomenology arising from a minimal vaccination-epidemic (MVE) dynamics using three methods: mean-field approach, Monte Carlo simulations, and finite-size scalin…
Self-similar but not conformally invariant traces obtained by modified Loewner forces
S. Tizdast, Z. Ebadi, J. Cheraghalizadeh +3
The two-dimensional Loewner exploration process is generalized to the case where the random force is self-similar with positively correlated increments. We model this random force…
Self-organized criticality in cumulus clouds
M. N. Najafi, J. Cheraghalizadeh, H. J. Herrmann
The shape of clouds has proven to be essential for classifying them. Our analysis of images from fair weather cumulus clouds reveals that, besides by turbulence they are driven by…
Frustrated bearings
R. S. Pires, A. A. Moreira, H. J. Herrmann +1
In a bearing state, touching spheres (disks in two dimensions) roll on each other without slip. Here we frustrate a system of touching spheres by imposing two different bearing sta…
Thermostat for a relativistic gas
Noah Kubli, Hans J. Herrmann
Molecular dynamics simulations of a three dimensional relativistic gas with a soft potential are conducted with different interactions and particle masses. For all cases the veloci…
Simulating isothermal aging of snow
Roman Vetter, Stephan Sigg, Herman M. Singer +3
A Monte Carlo algorithm to simulate the isothermal recrystallization process of snow is presented. The snow metamorphism is approximated by two mass redistribution processes, surfa…
