Reply to Comment on "Faceting and flattening of emulsion droplets: a mechanical model" by Haas et al
Ireth García-Aguilar, Ayelet Atkins, Piermarco Fonda +2
In their Comment [arXiv:2102.03842], Haas et al. advance two hypotheses on the nature of the shape transformations observed in surfactant-stabilized emulsion droplets, as the theor…
Supported lipid membranes with designed geometry
Melissa Rinaldin, Sebastiaan L. D. ten Haaf, Ernst J. Vegter +4
The membrane curvature of cells and intracellular compartments continuously adapts to enable cells to perform vital functions, from cell division to signal trafficking. Understandi…
Metastability of lipid necks via geometric triality
Piermarco Fonda, Luca Giomi
"Necks" are features of lipid membranes characterized by an uniquley large curvature, functioning as bridges between different compartments. These features are ubiquitous in the li…
Faceting and flattening of emulsion droplets: a mechanical model
Ireth García-Aguilar, Piermarco Fonda, Eli Sloutskin +1
When cooled down, emulsion droplets stabilized by a frozen interface of alkane molecules and surfactants have been observed to undergo a spectacular sequence of morphological trans…
Measuring Gaussian rigidity using curved substrates
Piermarco Fonda, Sami C. Al-Izzi, Luca Giomi +1
The Gaussian (saddle splay) rigidity of fluid membranes controls their equilibrium topology but is notoriously difficult to measure. In lipid mixtures, typical of living cells, lin…
Dislocation screening in crystals with spherical topology
Ireth García-Aguilar, Piermarco Fonda, Luca Giomi
Whereas disclination defects are energetically prohibitive in two-dimensional flat crystals, their existence is necessary in crystals with spherical topology, such as viral capsids…
Lipid exchange enhances geometric pinning in multicomponent membranes on patterned substrates
Melissa Rinaldin, Piermarco Fonda, Luca Giomi +1
Experiments on supported lipid bilayers featuring liquid ordered/disordered domains have shown that the spatial arrangement of the lipid domains and their chemical composition are…
On shape dependence of holographic entanglement entropy in AdS4/CFT3 with Lifshitz scaling and hyperscaling violation
Giacomo Cavini, Domenico Seminara, Jacopo Sisti +1
We study the divergent terms and the finite term in the expansion of the holographic entanglement entropy as the ultraviolet cutoff vanishes for smooth spatial regions having arbit…
Thermodynamic equilibrium of binary mixtures on curved surfaces
Piermarco Fonda, Melissa Rinaldin, Daniela J. Kraft +1
We study the global influence of curvature on the free energy landscape of two-dimensional binary mixtures confined on closed surfaces. Starting from a generic effective free energ…
Entanglement, anomalies and Mathisson's helices
Piermarco Fonda, Diego Liska, Alvaro Veliz-Osorio
We study the physical properties of a length-torsion functional which encodes the holographic entanglement entropy for 1+1 dimensional theories with chiral anomalies. Previously, w…
Interface geometry of binary mixtures on curved substrates
Piermarco Fonda, Melissa Rinaldin, Daniela J. Kraft +1
Motivated by recent experimental work on multicomponent lipid membranes supported by colloidal scaffolds, we report an exhaustive theoretical investigation of the equilibrium confi…
Geometric pinning and antimixing in scaffolded lipid vesicles
Melissa Rinaldin, Piermarco Fonda, Luca Giomi +1
Unravelling the physical mechanisms behind the organisation of lipid domains is a central goal in cell biology and membrane biophysics. Previous studies on cells and model lipid bi…
Spinning probes and helices in AdS
Piermarco Fonda, Diego Liska, Alvaro Veliz-Osorio
We study extremal curves associated with a functional which is linear in the curve's torsion. The functional in question is known to capture the properties of entanglement entropy…
On the Shape of Things: From holography to elastica
Piermarco Fonda, Vishnu Jejjala, Alvaro Veliz-Osorio
We explore the question of which shape a manifold is compelled to take when immersed in another one, provided it must be the extremum of some functional. We consider a family of fu…
Entanglement Entropy for Singular Surfaces in Hyperscaling violating Theories
Mohsen Alishahiha, Amin Faraji Astaneh, Piermarco Fonda +1
We study the holographic entanglement entropy for singular surfaces in theories described holographically by hyperscaling violating backgrounds. We consider singular surfaces consi…
On shape dependence of holographic mutual information in AdS4
Piermarco Fonda, Luca Giomi, Alberto Salvio +1
We study the holographic mutual information in AdS4 of disjoint spatial domains in the boundary which are delimited by smooth closed curves. A numerical method which approximates a…
Holographic thermalization with Lifshitz scaling and hyperscaling violation
Piermarco Fonda, Lasse Franti, Ville Keranen +3
A Vaidya type geometry describing gravitation collapse in asymptotically Lifshitz spacetime with hyperscaling violation provides a simple holographic model for thermalization near…
