As one increases the concentration of a colloidal suspension, the system exhibits a dramatic
increase in viscosity. Beyond a certain concentration, the system is said to be a colloidal …

非晶态物质是复杂的多体相互作用体系, 其基本特征是原子和电子结构复杂, 微观结构长程无序,
体系在能量上处在亚稳态, 具有复杂的多重弛豫行为, 其物理, 化学和力学性质 …

Soft materials consist of basic units that are significantly larger than an atom but much
smaller than the overall dimensions of the sample. The label “soft condensed matter” …

Amorphous solids lack long-range order. Therefore identifying structural defects—akin to
dislocations in crystalline solids—that carry plastic flow in these systems remains a daunting …

Many fundamental issues in classical condensed matter physics can be addressed
experimentally using systems of individually visible mesoscopic particles playing the role of …

Epithelial cell monolayers show remarkable displacement and velocity correlations over
distances of ten or more cell sizes that are reminiscent of supercooled liquids and active …

The boson peak is an excess in the phonon vibrational density of states relative to the
Debye model. It has been observed in a wide range of amorphous materials, from inorganic …

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 …

Connectedness and applied stress strongly affect elasticity in solids. In various amorphous
materials, mechanical stability can be lost either by reducing connectedness or by …

This review collects and describes experiments that employ colloidal suspensions to probe
physics in ordered and disordered solids and related complex fluids. The unifying feature of …
