Abstract

We present a hydrodynamic theory of anisotropic and inversion-asymmetric moving active permeable fluid membranes. These are described by an anisotropic Kardar-Parisi-Zhang equation. Depending upon the anisotropy parameters, the membrane is either effectively isotropic and algebraically rough with translational short, but orientational long-range order, or unstable, suggestive of membrane crumpling.

各向异性会使移动的主动流体膜变得粗糙或皱巴巴。

提出了一种各向异性和逆不对称运动主动渗透流体膜的水动力学理论。这些由各向异性kardar - paris - zhang方程描述。根据各向异性参数的不同，膜要么是有效的各向同性和代数粗糙的，具有平移短但定向的长程顺序，要么是不稳定的，暗示膜皱褶。

期刊介绍： Physical Review E (PRE), broad and interdisciplinary in scope, focuses on collective phenomena of many-body systems, with statistical physics and nonlinear dynamics as the central themes of the journal. Physical Review E publishes recent developments in biological and soft matter physics including granular materials, colloids, complex fluids, liquid crystals, and polymers. The journal covers fluid dynamics and plasma physics and includes sections on computational and interdisciplinary physics, for example, complex networks.
