Finite-size scaling at the jamming transition by Goodrich, Carl P, Liu, Andrea J, Nagel, Sidney R

“…We present an analysis of finite-size effects in jammed packings of N soft, frictionless spheres at zero temperature. There is a 1/N correction to the discrete…”

Two Diverging Length Scales in the Structure of Jammed Packings by Hexner, Daniel, Liu, Andrea J, Nagel, Sidney R

“…At densities higher than the jamming transition for athermal, frictionless repulsive spheres we find two distinct length scales, both of which diverge as a…”

The Jamming Transition and the Marginally Jammed Solid by Liu, Andrea J, Nagel, Sidney R

“…When a system jams, it undergoes a transition from a flowing to a rigid state. Despite this important change in the dynamics, the internal structure of the…”

Stretchable Superhydrophobicity from Monolithic, Three-Dimensional Hierarchical Wrinkles by Lee, Won-Kyu, Jung, Woo-Bin, Nagel, Sidney R, Odom, Teri W

“…We report the design of three-dimensional (3D) hierarchical wrinkle substrates that can maintain their superhydrophobicity even after being repeatedly…”

Ultrafast interference imaging of air in splashing dynamics by Driscoll, Michelle M, Nagel, Sidney R

“…A drop impacting a solid surface with sufficient velocity will emit many small droplets creating a splash. However, splashing is completely suppressed if the…”

Solids between the mechanical extremes of order and disorder by Goodrich, Carl P., Liu, Andrea J., Nagel, Sidney R.

“…Jammed systems are typically thought of as being amorphous. Simulations of packings with varying disorder reveal a crossover from crystalline behaviour, which…”

Viscous to inertial crossover in liquid drop coalescence by Paulsen, Joseph D, Burton, Justin C, Nagel, Sidney R

“…Using an electrical method and high-speed imaging, we probe drop coalescence down to 10 ns after the drops touch. By varying the liquid viscosity over two…”

Creation of prompt and thin-sheet splashing by varying surface roughness or increasing air pressure by Latka, Andrzej, Strandburg-Peshkin, Ariana, Driscoll, Michelle M, Stevens, Cacey S, Nagel, Sidney R

“…A liquid drop impacting a solid surface may splash either by emitting a thin liquid sheet that subsequently breaks apart or by promptly ejecting droplets from…”

The inexorable resistance of inertia determines the initial regime of drop coalescence by Paulsen, Joseph D., Burton, Justin C., Nagel, Sidney R., Appathurai, Santosh, Harris, Michael T., Basaran, Osman A.

“…Drop coalescence is central to diverse processes involving dispersions of drops in industrial, engineering, and scientific realms. During coalescence, two…”

The role of rigidity in controlling material failure by Driscoll, Michelle M., Chen, Bryan Gin-ge, Beuman, Thomas H., Ulrich, Stephan, Nagel, Sidney R., Vitelli, Vincenzo

“…We investigate how material rigidity acts as a key control parameter for the failure of solids under stress. In both experiments and simulations, we…”

Equivalence of glass transition and colloidal glass transition in the hard-sphere limit by Xu, Ning, Haxton, Thomas K, Liu, Andrea J, Nagel, Sidney R

“…We show that the slowing of the dynamics in simulations of several model glass-forming liquids is equivalent to the hard-sphere glass transition in the…”

Towards the zero-surface-tension limit in granular fingering instability by Cheng, Xiang, Xu, Lei, Patterson, Aaron, Jaeger, Heinrich M, Nagel, Sidney R

“…The finger-like branching pattern that occurs when a less viscous fluid displaces a more viscous one confined between two parallel plates has been widely…”

Energy loss at propagating jamming fronts in granular gas clusters by Burton, Justin C, Lu, Peter Y, Nagel, Sidney R

“…We explore the initial moments of impact between two dense granular clusters in a two-dimensional geometry. The particles are composed of solid CO(2) and are…”

Fingering versus stability in the limit of zero interfacial tension by Bischofberger, Irmgard, Ramachandran, Radha, Nagel, Sidney R.

“…The invasion of one fluid into another of higher viscosity in a quasi-two dimensional geometry typically produces complex fingering patterns. Because…”

Still water: dead zones and collimated ejecta from the impact of granular jets by Ellowitz, Jake, Turlier, Hervé, Guttenberg, Nicholas, Zhang, Wendy W, Nagel, Sidney R

“…When a dense granular jet hits a target, it forms a large dead zone and ejects a highly collimated conical sheet with a well-defined opening angle. Using…”
