where 𝜖 is the characteristic energy, σ represents the size of the particle and 𝑟 the distance between particles. Our simulation truncates this potential at the cut-off distance 2.5𝜎. The simulation results are described using reduced LJ units. For simplicity, we consider particles of all the same size, mass (𝑚) and characteristic energy for interatomic potentials (𝑚 = 1, 𝜎 = 1 and 𝜖 = 1). Temperature is described by reduced temperature, where 𝑇 * = 𝑇 𝑘 9 𝜖 : and 𝑘 9 represents the Boltzmann constant. Importantly, time is defined as 𝜏 = (𝜖/𝑚𝜎 . ) -/. 𝑡. We have employed these units here for simplicity, as the aim of this study is a qualitative assessment of molecular motor systems in confined fluids. The timestep for simulations was set to 0.005 𝜏.
