Domain growth in lipid membranes and the budding instability
Jean Wolff, Fabrice Thalmann, Carlos Marques +3
We investigate the growth of a circular domain in a phase-separating lipid membrane and its relation to the budding instability. We describe the in-plane dynamics with a conserved,…
Phase transitions and microphases in elastomers. II. Anisotropy-driven morphologies
Manu Mannattil, David Andelman, Haim Diamant
In swollen elastomers, elasticity can arrest macroscopic demixing between the polymer network and the solvent, producing stable domains of finite size. While previous theories have…
Phase transitions and microphases in elastomers. I. Emergence of stable domains
Manu Mannattil, Haim Diamant, David Andelman
Elasticity often plays a key role in regulating phase separation in physical systems. Recent experiments have shown that elastic effects can be used to control microphase separatio…
The effects of ionic valency and size asymmetry on counterion adsorption
Or Ben Yaakov, Haim Diamant, Rudolf Podgornik +1
We study the effect of asymmetry in solvent and ionic size on the equilibrium properties of multivalent ionic solutions near a charged surface. For a single ionic species in soluti…
Collapse of a single polymer chain: Effects of chain stiffness and attraction range
Yanyan Zhu, Haim Diamant, David Andelman
Chain-like macromolecules in solution, whether biological or synthetic, transform from an extended conformation to a compact one when temperature or other system parameters change.…
Theory of Microphase Separation in Elastomers
Manu Mannattil, Haim Diamant, David Andelman
Inspired by recent experiments, we present a phase-field model of microphase separation in an elastomer swollen with a solvent. The imbalance between the molecular scale of demixin…
Detecting and characterizing phase transitions in active matter using entropy
Benjamin Sorkin, Avraham Be'er, Haim Diamant +1
A major challenge in the study of active matter lies in quantitative characterization of phases and transitions between them. We show how the entropy of a collection of active obje…
Structured viscoelastic substrates as linear foundations
Chen Bar-Haim, Haim Diamant
The linear (Winkler) foundation is a simple model widely used for decades to account for the surface response of elastic bodies. It models the response as purely local, linear, and…
Parametric excitation of wrinkles in elastic sheets on elastic and viscoelastic substrates
Haim Diamant
Thin elastic sheets supported on compliant media form wrinkles under lateral compression. Since the lateral pressure is coupled to the sheet's deformation, varying it periodically…
Symmetry properties of nonlinear hydrodynamic interactions between responsive particles
Yulia Sokolov, Haim Diamant
Two identical particles driven by the same steady force through a viscous fluid may move relative to one another due to hydrodynamic interactions. The presence or absence of this r…
Surface response of a polymer network: Semi-infinite network
Chen Bar-Haim, Haim Diamant
We study theoretically the surface response of a semi-infinite viscoelastic polymer network using the two-fluid model. We focus on the overdamped limit and on the effect of the net…
Delayed nucleation in lipid particles
Guy Jacoby, Irina Portnaya, Dganit Danino +2
Metastable states in first-order phase-transitions have been traditionally described by classical nucleation theory (CNT). However, recently an increasing number of systems display…
Permeability of immobile rings of membrane inclusions to in-plane flow
Yulia Sokolov, Haim Diamant
We study the flow of membranal fluid through a ring of immobile particles mimicking, for example, a fence around a membrane corral. We obtain a simple closed-form expression for th…
Screening length for finite-size ions in concentrated electrolytes
Ram M. Adar, Samuel A. Safran, Haim Diamant +1
The classical Debye-Huckel (DH) theory clearly accounts for the origin of screening in electrolyte solutions and works rather well for dilute electrolyte solutions. While the Debye…
Many-particle mobility and diffusion tensors for objects in viscous sheets
Yulia Sokolov, Haim Diamant
We derive a mobility tensor for many cylindrical objects embedded in a viscous sheet. This tensor guarantees a positive dissipation rate for any configuration of particles and forc…
Correlations in suspensions confined between viscoelastic surfaces: Noncontact microrheology
Chen Bar-Haim, Haim Diamant
We study theoretically the velocity cross-correlations of a viscous fluid confined in a slit between two viscoelastic media. We analyze the effect of these correlations on the moti…
Membrane undulations in a structured fluid: Universal dynamics at intermediate length and time scales
Rony Granek, Haim Diamant
The dynamics of membrane undulations inside a viscous solvent is governed by distinctive, anomalous, power laws. Inside a viscoelastic continuous medium these universal behaviors a…
Pattern transitions in a compressible floating elastic sheet
Oz Oshri, Haim Diamant
Thin rigid sheets floating on a liquid substrate appear, for example, in coatings and surfactant monolayers. Upon uniaxial compression the sheet undergoes transitions from a compre…
Electrostatics of Patchy Surfaces
Ram M. Adar, David Andelman, Haim Diamant
In the study of colloidal, biological and electrochemical systems, it is customary to treat surfaces, macromolecules and electrodes as homogeneously charged. This simplified approa…
Screening, Hyperuniformity, and Instability in the Sedimentation of Irregular Objects
Tomer Goldfriend, Haim Diamant, Thomas A. Witten
We study the overdamped sedimentation of non-Brownian objects of irregular shape using fluctuating hydrodynamics. The anisotropic response of the objects to flow, caused by their t…
Strain tensor selection and the elastic theory of incompatible thin sheets
Oz Oshri, Haim Diamant
The existing theory of incompatible elastic sheets uses the deviation of the surface metric from a reference metric to define the strain tensor [Efrati et al., J. Mech. Phys. Solid…
Electrostatic Attraction between Overall Neutral Surfaces
Ram M. Adar, David Andelman, Haim Diamant
Two overall neutral surfaces with positive and negative charged domains ("patches") have been shown in recent experiments to exhibit long-range attraction when immersed in an ionic…
Free energy approach to micellization and aggregation: Equilibrium, metastability, and kinetics
Haim Diamant, David Andelman
We review a recently developed micellization theory, which is based on a free-energy approach and offers several advantages over the conventional one, based on mass action and rate…
Elasticity and Fluctuations of Frustrated Nano-Ribbons
Doron Grossman, Eran Sharon, Haim Diamant
We derive a reduced quasi-one-dimensional theory of geometrically frustrated elastic ribbons. Expressed in terms of geometric properties alone, it applies to ribbons over a wide ra…
