We experimentally study the jamming of quasi-two-dimensional emulsions. Our experiments consist of oil-in-water emulsion droplets confined between two parallel plates. From the droplet outlines, we can determine the forces between every droplet over a wide range of area fractions ϕ. We study three bidisperse samples that jam at area fractions ϕc ≈ 0.86. Our data show that for ϕ > ϕc, the contact numbers and pressure have power-law dependence on ϕ − ϕc in agreement with the critical scaling… 
Clogging and avalanches in quasi-two-dimensional emulsion hopper flow
We experimentally and computationally study the flow of a quasi-two-dimensional emulsion through a constricting hopper shape. Our area fractions are above jamming such that the droplets are always in
Clogging of soft particles in two-dimensional hoppers.
TLDR
The results suggest that prior studies using hard particles were in a limit where the role of softness is negligible, which causes clogging to occur with significantly larger openings, and that with stiffer particles or a weaker gravitational force, clogging is easier.
Can liquid foams and emulsions be modeled as packings of soft elastic particles?
TLDR
Analytical ab initio models and simulations are reviewed, based on the equilibration of pressure and surface tension forces or, equivalently, minimization of interfacial energy, and applications are explored in two and three dimensions.
Experimental observation of local rearrangements in dense quasi-two-dimensional emulsion flow.
TLDR
Flowing droplets are deformed due to forces from neighboring droplets, and these deformations are decreased by nearby T1 events, with a spatial dependence related to the local structure.
Random three-dimensional jammed packings of elastic shells acting as force sensors.
TLDR
Close to the unjamming-jamming transition (point J), the probability distribution of the interparticle forces P(f) to decay nearly exponentially at large forces, with little evidence of long-range force chains in the packings.
The role of deformability in determining the structural and mechanical properties of bubbles and emulsions.
TLDR
Computational studies of jammed particle packings in two dimensions undergoing isotropic compression using the well-characterized soft particle (SP) model and deformable particle (DP) model that was developed for bubbles and emulsions agree with recent experimental studies of foams andEmulsions.
Many-body interactions in soft jammed materials.
TLDR
An asymptotic two-body interaction law is derived that contains a logarithmic term, yielding a critical scaling that cannot be approximated by a power law.
Experimental study of some properties of the strong and weak force networks in a jammed granular medium
Abstract We are experimentally investigating the force network of a monolayer of grains through the jamming transition. Once the packing has been compressed beyond the volume fraction of jamming
Avalanches of rearrangements in quasi-2D emulsion hopper flow
We experimentally study the flow of a quasi-two-dimensional emulsion through a constricting hopper shape. Our area fractions range from 0.83 to 0.99, such that the droplets are always in contact with
Aspects of jamming in two-dimensional athermal frictionless systems.
TLDR
This work discusses jamming in systems with short range repulsive interactions, where the onset of jamming occurs at a critical packing density and where certain quantities show a divergence indicative of critical behavior.

Topological rearrangements and stress fluctuations in quasi-two-dimensional hopper flow of emulsions
We experimentally study the shear flow of oil-in-water emulsion droplets in a thin sample chamber with a hopper shape. In this thin chamber, the droplets are quasi-2D in shape. The sample is at an
Measurement of Forces Inside a Three-Dimensional Pile of Frictionless Droplets
TLDR
It is found that piles whose height was comparable to the chain persistence length exhibited substantially greater strain hardening than did tall piles, which were attributed to the force chains.
3D bulk measurements of the force distribution in a compressed emulsion system.
TLDR
The simplest form of the Boltzmann equation for the probability of force distributions predicts P(f) to be of the form e(-f/p), where p is proportional to the mean force f for large forces, in good agreement with experimental and simulated data.
Contact force measurements and stress-induced anisotropy in granular materials
TLDR
Measurements of the normal and tangential grain-scale forces inside a two-dimensional system of photoelastic disks that are subject to pure shear and isotropic compression show the underlying differences between these two stress states.
TOPICAL REVIEW: Jamming of soft particles: geometry, mechanics, scaling and isostaticity
Amorphous materials as diverse as foams, emulsions, colloidal suspensions and granular media can jam into a rigid, disordered state where they withstand finite shear stresses before yielding. Here we
Jamming at zero temperature and zero applied stress: the epitome of disorder.
TLDR
The results provide a well-defined meaning for "random close packing" in terms of the fraction of all phase space with inherent structures that jam, and suggest that point J is a point of maximal disorder and may control behavior in its vicinity-perhaps even at the glass transition.

Fluctuations in granular media.
TLDR
The force distributions computed from the 3D stress time series are at least qualitatively consistent with exponential fall-off at large stresses.

Model for the elasticity of compressed emulsions.
TLDR
A new effective inter-droplet potential is proposed which is used to determine the elastic response of a monodisperse collection of disordered droplets as a function of volume fraction, and suggests that anharmonicity and disorder are responsible for the quasi-linear increase of G and Pi observed at $\varphi_c".
