受限膜动力学中的冻结态和有序-无序转变

Frozen states and order-disorder transition in the dynamics of confined membranes

Thomas Le Goff, Paolo Politi, Olivier Pierre-Louis

摘要:

采用二维流体力学模型研究了两个可渗透壁之间的膜的粘附动力学。膜形态分解成上壁和下壁上的粘附片,并且服从类似于相分离动力学的非线性演化方程,已知这导致粗化,即粘附片的无限生长。然而,由于膜的抗弯刚度,系统向冻结状态演化而不粗化。当增加壁的渗透性时,这种冻结状态表现出有序-无序转变。

英文摘要:

The adhesion dynamics of a membrane confined between two permeable walls is studied using a two-dimensional hydrodynamic model. The membrane morphology decomposes into adhesion patches on the upper and the lower walls and obeys a nonlinear evolution equation that resembles that of phase separation dynamics, which is known to lead to coarsening, i.e. to the endless growth of the adhesion patches. However, due to the membrane bending rigidity the system evolves towards a frozen state without coarsening. This frozen state exhibits an order-disorder transition when increasing the permeability of the walls.
