Liquid crystalline order and its impact on shape evolution of fluid lipid membranes
Ingo Nitschke, Maik Porrmann, Axel Voigt
Dynamic approaches to minimize the classical curvature-elasticity free energy for a fluid lipid membrane, are extended towards a Surface Beris--Edwards--Helfrich model. This extens…
Hydrodynamic liquid crystal models for lipid bilayers
Ingo Nitschke, Jan Magnus Sischka, Axel Voigt
Coarse-grained continuous descriptions for lipid bilayers are typically based on minimizing the Helfrich energy. Such models consider the fluid properties of these structures only…
A topological approach to the Cahn-Hilliard equation and hyperuniform fields
Abel H. G. Milor, Otto Sumray, Heather A. Harrington +2
Hyperuniform structures are disordered, correlated systems in which density fluctuations are suppressed at large scales. Such a property generalizes the concept of order in pattern…
The influence of higher order geometric terms on the asymmetry and dynamics of membranes
Jan Magnus Sischka, Ingo Nitschke, Axel Voigt
We consider membranes as fluid deformable surface and allow for higher order geometric terms in the bending energy. The evolution equations are derived and numerically solved using…
Active nematodynamics on deformable surfaces
Ingo Nitschke, Axel Voigt
We consider active nematodynamics on deformable surfaces. Based on a thermodynamically consistent surface Beris-Edwards model we add nematic activity and focus on the emerging addi…
Nonequilibrium hyperuniform states in active turbulence
Rainer Backofen, Abdelrahman Y. A. Altawil, Marco Salvalaglio +1
We demonstrate that the complex spatiotemporal structure in active fluids can feature characteristics of hyperuniformity. Using a hydrodynamic model, we show that the transition fr…
