Abstract
Maia Pancost, Madison Wolf, Qi-Huo Wei Department of Physics, and Advanced Materials and Liquid Crystal Institute, Kent State University, Kent, OH 44242 Active particles, also known as self-propelled Brownian particles, can convert the energy of their surroundings into directed motion. Driven by the constant source of external energy, systems of these active particles are usually out of equilibrium, and thus behave differently from these equilibrium systems made of passive particles. The overall goal of this project is to explore the potential to controlling active systems by structured external fields. Here we use numerical simulations based on Langevin equations to study the behavior of single active particle subject to spatially variant external driving field. The environment will be minimal at first, just focusing on a spherical particle with only a random force acting on it. The final code will include a rod-shaped particle surrounded by similar particles, as well as the possible interactions between those particles and extraneous barriers placed throughout the environment. The movement and interactions of these particles in the coded environment will be analyzed and compared to the real life movement of these particles.

Modified Abstract

Active particles, also known as self-propelled Brownian particles, can convert the energy of their surroundings into directed motion. Driven by the constant source of external energy, systems of these active particles are usually out of equilibrium, and thus behave differently from these equilibrium systems made of passive particles. The overall goal of this project is to explore the potential to controlling active systems by structured external fields. Here we use numerical simulations based on Langevin equations to study the behavior of single active particle subject to spatially variant external driving field. The environment will be minimal at first, just focusing on a spherical particle with only a random force acting on it. The final code will include a rod-shaped particle surrounded by similar particles, as well as the possible interactions between those particles and extraneous barriers placed throughout the environment. The movement and interactions of these particles in the coded environment will be analyzed and compared to the real life movement of these particles.

We will be providing our own poster board and materials, all we need is a table.
