A minimal actin cortex was bound to a supported lipid bilayer via biotinylated lipid streptavidin complexes (pinning sites). In general, actin binding to ternary membranes prevented macroscopic liquid-ordered (Lo) and liquid-disordered (Ld) domain formation in these systems, even at low temperature. For pinning sites that strongly attract Ld domains, an actin correlated multi-domain pattern was observed, consisting of Ld “channels” along the actin fibers, with Lo “islands” in the voids. FCS measurements revealed enhanced diffusion of unsaturated lipids along the channels, and hindered diffusion of these lipids in directions perpendicular. For pinning sites strongly attractive to Lo domains, an “inverse” domain structure was observed. These findings are in good agreement with a number of recently proposed simulation models. However, to fully capture our experimental observations, an extended simulation model is proposed, in which the lipid domains also couple to the local membrane curvature.

We find that, on the atomic scale, the friction tensor can drastically vary as a function of position and sliding direction. The Green-Kubo relation yields this positional and directional dependence from equilibrium simulations of the time dependent covariance of force acting on the probe. We find, unexpectedly, that the positional and directional dependence of energy dissipation is related to the (much simpler) static force covariance, especially in the limit where the probe only mildly perturbs the surface particles. In contrast, the (free) energy landscape experienced by the probe is in general not a good indicator of local dissipation. We also discuss optimization strategies making use of the locally and directionally resolved friction tensor. This enables us to find optimal sliding paths and velocity protocols, e.g., minimizing energy dissipation, between two points on the surface in a given time."],["dc.identifier.arxiv","2003.14219v3"],["dc.identifier.doi","10.1103/PhysRevB.101.235426"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/79358"],["dc.language.iso","en"],["dc.relation","SFB 1073: Kontrolle von Energiewandlung auf atomaren Skalen"],["dc.relation","SFB 1073 | Topical Area A | A01 Reibung unter aktiver Kontrolle in Systemen mit optimierten Freiheitsgraden"],["dc.relation.issn","2469-9950"],["dc.relation.issn","2469-9969"],["dc.relation.orgunit","Institut für Materialphysik"],["dc.title","Spatially resolved atomic-scale friction: Theory and Simulation"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.subtype","original_ja"],["dspace.entity.type","Publication"]]
