AMEP: The active matter evaluation package for Python

L Hecht, KR Dormann, KL Spanheimer… - Computer Physics …, 2025 - Elsevier
Abstract The Active Matter Evaluation Package (AMEP) is a Python library for analyzing
simulation data of particle-based and continuum simulations. It provides a powerful and …

Universal critical behavior of percolation in orientationally ordered Janus particles and other anisotropic systems

H Hu, RM Ziff, Y Deng - Physical Review Letters, 2022 - APS
We combine percolation theory and Monte Carlo simulation to study in two dimensions the
connectivity of an equilibrium lattice model of interacting Janus disks which self-assemble …

Phases and homogeneous ordered states in alignment-based self-propelled particle models

Y Zhao, T Ihle, Z Han, C Huepe, P Romanczuk - Physical Review E, 2021 - APS
We study a set of models of self-propelled particles that achieve collective motion through
similar alignment-based dynamics, considering versions with and without repulsive …

Percolation transition in phase-separating active fluid

M Sanoria, R Chelakkot, A Nandi - Physical Review E, 2022 - APS
The motility-induced phase separation exhibited by active particles with repulsive
interactions is well known. We show that the interaction softness of active particles …

Percolation transitions in a binary mixture of active Brownian particles with different softness

M Sanoria, R Chelakkot, A Nandi - Soft Matter, 2024 - pubs.rsc.org
Homogeneous active Brownian particle (ABP) systems with purely repulsive interactions are
considered to exhibit a simple phase behavior, but various physical attributes of active …

Collective motion of self-propelled particles with complex noise environments

BQ Zhang, ZG Shao - Physica A: Statistical Mechanics and its Applications, 2021 - Elsevier
Collective motion of self-propelled particles with complex noise environments is investigated
via simulations based on the Vicsek model. In our model, self-propelled particles move in a …

Swarming Transition in Super-Diffusive Self-Propelled Particles

M Nattagh Najafi, RMA Zayed, SA Nabavizadeh - Entropy, 2023 - mdpi.com
A super-diffusive Vicsek model is introduced in this paper that incorporates Levy flights with
exponent α. The inclusion of this feature leads to an increase in the fluctuations of the order …

Active adaptolates: motility-induced percolating structures with an adaptive packing geometry

AK Mukhopadhyay, P Schmelcher… - arXiv preprint arXiv …, 2023 - arxiv.org
It is well known that periodic potentials can be used to induce freezing and melting in
colloids. Here, we transfer this concept to active systems and find the emergence of a so-far …

Aggregation of self-propelled particles with sensitivity to local order

K Bhattacharya, A Chakraborty - Physical Review E, 2022 - APS
We study a system of self-propelled particles (SPPs) in which individual particles are
allowed to switch between a fast aligning and a slow nonaligning state depending upon the …

Collective pattern formation in a binary mixture of self-propelled particles

S Adhikary, SB Santra - Journal of Physics: Conference Series, 2022 - iopscience.iop.org
We have studied the collective behaviour of a binary mixture of self-propelled particles
(SPPs) with non-identical motile properties. The two types of SPPs with low and high velocity …
