A comprehensive review is presented of the physical behavior of yield stress materials in
soft condensed matter, which encompasses a broad range of materials from colloidal …

Despite decades of work, gaining a first-principles understanding of amorphous materials
remains an extremely challenging problem. However, recent theoretical breakthroughs have …

Jamming is a ubiquitous phenomenon that appears in many soft matter systems, including
granular materials, foams, colloidal suspensions, emulsions, polymers, and cells—when …

Glassy solids exhibit a wide variety of generic thermomechanical properties, ranging from
universal anomalous specific heat at cryogenic temperatures to nonlinear plastic yielding …

Low-frequency vibrational modes play a central role in determining various basic properties
of glasses, yet their statistical and mechanical properties are not fully understood. Using …

In 1989, Sir Sam Edwards made the visionary proposition to treat jammed granular materials
using a volume ensemble of equiprobable jammed states in analogy to thermal equilibrium …

We report an analytical study of the vibrational spectrum of the simplest model of jamming,
the soft perceptron. We identify two distinct classes of soft modes. The first kind of modes are …

It is now well established that structural glasses possess disorder-and frustration-induced
soft quasilocalized excitations, which play key roles in various glassy phenomena. Recent …

It has been recently established that the low-frequency spectrum of simple computer glass
models is populated by soft, quasilocalized nonphononic vibrational modes whose …

We revisit the concept of marginal stability in glasses and determine its range of applicability
in the context of an avalanche-type response to slow external driving. We argue that there is …
