# Metastable Clusters and Channels Formed by Active Particles with Aligning Interactions

## TL;DR

This paper presents a new model for active particles with aligning interactions, revealing transitions from gaseous states to clusters and channels in crowded environments through numerical simulations.

## Contribution

It introduces a novel active particle model with short-range alignment and explores complex behaviors like clustering and channel formation.

## Key findings

- Transition from gaseous to clustered states as noise decreases
- Formation of metastable channels in mixed active-passive systems
- Numerical simulations demonstrate complex collective behaviors

## Abstract

We introduce a novel model for active particles with short-range aligning interactions and study their behaviour in crowded environments using numerical simulations. When only active particles are present, we observe a transition from a gaseous state to the emergence of metastable clusters as the level of orientational noise is reduced. When also passive particle are present, we observe the emergence of a network of metastable channels.
