Effects of passive phospholipid flip-flop and asymmetric external fields on bilayer phase equilibria
John J. Williamson, Peter D. Olmsted
Compositional asymmetry between the leaflets of bilayer membranes modifies their phase behaviour, and is thought to influence other important features such as mechanical properties…
Stability and roughness of interfaces in mechanically-regulated tissues
John J. Williamson, Guillaume Salbreux
Cell division and death can be regulated by the mechanical forces within a tissue. We study the consequences for the stability and roughness of a propagating interface, by analysin…
Comment on "Elastic Membrane Deformations Govern Interleaflet Coupling of Lipid-Ordered Domains"
John J. Williamson, Peter D. Olmsted
In lieu of abstract, first paragraph reads: Galimzyanov et al. [1] find that line tension between thick liquid-ordered () and thinner liquid-disordered () registered…
Nucleation of symmetric domains in the coupled leaflets of a bilayer
John J. Williamson, Peter D. Olmsted
We study the kinetics governing the attainment of inter-leaflet domain symmetry in a phase-separating amphiphilic bilayer. "Indirect" inter-leaflet coupling via hydrophobic mismatc…
Kinetics of symmetry and asymmetry in a phase-separating bilayer membrane
John J. Williamson, Peter D. Olmsted
We simulate a phase-separating a bilayer in which the leaflets experience a direct coupling favouring local compositional symmetry ("registered" bilayer phases), and an indirect co…
Registered and antiregistered phase separation of mixed amphiphilic bilayers
John J. Williamson, Peter D. Olmsted
We derive a mean-field free energy for the phase behaviour of coupled bilayer leaflets, which is implicated in cellular processes and important to the design of artificial membrane…
Effects of the Carnahan-Starling free energy within theories of fluids with short-range attraction
John J. Williamson, R. Mike L. Evans, Wilson C. K. Poon +1
Within the Free-Volume Asakura-Oosawa-Vrij (FVAO) theory of colloid-polymer mixtures, we show that unphysical gas-liquid binodals predicted in the regime of small attraction range…
