Dynamics of active deformable particles in flow field
アブストラクト：
Dynamics of active deformable particles is investigated theoretically by
using model equations derived from symmetry argument. We consider a
particle in an external flow field and introduce time-evolution equations
for the centre-of-mass position and velocity vector variables, symmetric
tensor variables representing deformation, and an anti-symmetric tensor
variable characterising the rotation of the particle.
In this seminar, we would talk about the dynamics in the following three
situations. One is the case of a quiescent flow filed, where we
concentrate on the spinning motions of active deformable particles and
argue that there are at least two types of spinning motions. Then, a
linear shear flow is taken into consideration as simplest flow geometry.
Finally, the dynamics in a swirl is investigated. Since the flow profile
of a swirl is similar to that of a scattering geometry and possesses
therefore analogy to the classical Kepler and Rutherford problem, we
investigate an analogous setup in the context of active particles.
