| Summary: | This study introduces a unique active matter system as an application of the
pedestrian collision avoidance paradigm, that proposes dynamically adjusting
the desired velocity. We present a fictitious human-zombie scenario set within
a closed geometry, combining prey-predator behavior with a one-way contagion
process that can transform prey into predators. The system demonstrates varied
responses, in cases where agents have the same maximum speeds, a single zombie
always catches a human, whereas two zombies never catch a single human. As the
number of human agents increases, observables, such as the final fraction of
zombie agents and total conversion times, exhibit a significant change in the
system's behavior at intermediate density values. Most notably, there is
evidence of a first-order phase transition when the mean population speed is
analyzed as an order parameter. |
