Deformation-induced spectral softening drives phase separation on non-spherical membranes
Avraham Moriel, Howard A. Stone
Models of curvature-driven membrane sorting couple composition directly to membrane bending elasticity. Here we show that shape deformations can destabilize a homogeneous state wit…
Nonlinear diffusion and compressive rims in source-driven biopolymer condensates
Avraham Moriel, Howard A. Stone
Many subcellular condensates continuously produce biopolymers. Coupling Flory-Huggins thermodynamics to two-fluid viscoelasticity, we probe the diffusion of such source-driven poly…
Polymer-polymer interdiffusion: effects of entanglements and a polymeric source
Avraham Moriel, Howard A. Stone
Many industrial applications and biological scenarios involve the interdiffusion of two polymeric species. Motivated by biological subcellular source-driven processes, we study pol…
Enucleated incompressible red blood cells in shear flow: theoretical analysis of shape instabilities
Avraham Moriel, Howard A. Stone, Simon Mendez
Red blood cells (RBCs) are essential for oxygen transport, and their remarkable ability to undergo significant deformations during flow is a crucial feature for their physiological…
Enumerating low-frequency nonphononic vibrations in computer glasses
Edan Lerner, Avraham Moriel, Eran Bouchbinder
In addition to Goldstone phonons that generically emerge in the low-frequency vibrational spectrum of any solid, crystalline or glassy, structural glasses also feature other low-fr…
Experimental evidence for the tail of the nonphononic spectra of glasses
Avraham Moriel, Edan Lerner, Eran Bouchbinder
It is now established that glasses feature low-frequency, nonphononic excitations, in addition to phonons that follow Debye's vibrational density of state (VDoS). Extensive compute…
Elementary processes in dilatational plasticity of glasses
Avraham Moriel, David Richard, Edan Lerner +1
Materials typically fail under complex stress states, essentially involving dilatational (volumetric) components that eventually lead to material decohesion/separation. It is there…
Self-Driven Configurational Dynamics in Frustrated Spring-Mass Systems
Ori Saporta-Katz, Avraham Moriel
Various physical systems relax mechanical frustration through configurational rearrangements. We examine such rearrangements via Hamiltonian dynamics of simple internally-stressed…
The boson peak in the vibrational spectra of glasses
Avraham Moriel, Edan Lerner, Eran Bouchbinder
A hallmark of glasses is an excess of low-frequency, nonphononic vibrations, in addition to phonons. It is associated with the intrinsically nonequilibrium and disordered nature of…
Internally-stressed and positionally-disordered minimal complexes yield glasslike nonphononic excitations
Avraham Moriel
Glasses, unlike their crystalline counterparts, exhibit low-frequency nonphononic excitations whose frequencies follow a universal dens…
Extracting the properties of quasilocalized modes in computer glasses: Long-range continuum fields, contour integrals and boundary effects
Avraham Moriel, Yuri Lubomirsky, Edan Lerner +1
Low-frequency nonphononic modes and plastic rearrangements in glasses are spatially quasilocalized, i.e. feature a disorder-induced short-range core and known long-range decaying e…
Wave attenuation in glasses: Rayleigh and generalized-Rayleigh scattering scaling
Avraham Moriel, Geert Kapteijns, Corrado Rainone +3
The attenuation of long-wavelength phonons (waves) by glassy disorder plays a central role in various glass anomalies, yet it is neither fully characterized, nor fully understood.…
Finite-size effects on sound damping in stable computer glasses
Corrado Rainone, Avraham Moriel, Geert Kapteijns +2
In this brief note we comment on the recent results presented in arXiv:1812.08736v1
Necking instabilities in elasto-viscoplastic materials
Avraham Moriel, Eran Bouchbinder
Necking instabilities, in which tensile (extensional) deformation localizes into a small spatial region, are generic failure modes in elasto-viscoplastic materials. Materials in th…
An Efficient Coding Theory for a Dynamic Trajectory Predicts non-Uniform Allocation of Grid Cells to Modules in the Entorhinal Cortex
Noga Weiss Mosheiff, Haggai Agmon, Avraham Moriel +1
Grid cells in the entorhinal cortex encode the position of an animal in its environment using spatially periodic tuning curves of varying periodicity. Recent experiments establishe…
