研究兴趣：Flow-induced swimming order in collective bacterial crowd
Active matter systems are made up of units that propel themselves by consume bio or chemical energy. Physicists group flocks of birds, molecular motors and layers of vibrating grains together in this category because they all extract energy from their surroundings at a single particle level and transform it into mechanical work. By studying the behavior that emerge, our understanding of these systems can be enhanced and new frameworks for investigating the statistical physics of out-of-equilibrium systems can be built.
However, how does the formation of the collective motion with the order of large length scale than the size of the individual, is fundamental important but far from well understood. Inspired from the magnetic polarization, we ask the question here, how the bacteria are aligned due to the shear stress in Poiseille flow. The order parameter analogy to the magnetization $M$, can be defined in the active system, and the similar hysteresis curve ($M~\dot{\gamma}$) can be measured experimentally.
For this purpose, we develop the microfluidic channels, and track the bacteria swimming responsing to the shear flow. Data analysis will be performed to define all the variables corresponding to the magetic polariation, such as, saturation magnetization$M_s$, permeability $\chi$, Coercivity$\gamma_c$.
