When cooled or pressurized, polymer melts exhibit a tremendous reduction in molecular
mobility. If the process is performed at a constant rate, the structural relaxation time of the …

Understanding the physics of glass formation remains one of the major unsolved challenges
of condensed matter science. As a material solidifies into a glass, it exhibits a spectacular …

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 …

The physical nature of the bacterial cytoplasm is poorly understood even though it
determines cytoplasmic dynamics and hence cellular physiology and behavior. Through …

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 remarkable kinetic slowdown experienced by liquids as they are cooled toward their
glass transition is not accompanied by any obvious structural change. Understanding the …

The viscosity of a liquid measures its resistance to flow, with consequences for hydraulic
machinery, locomotion of microorganisms, and flow of blood in vessels and sap in trees …

We use x-ray photon correlation spectroscopy to investigate the structural relaxation process
in a metallic glass on the atomic length scale. We report evidence for a dynamical crossover …

The simplest way to make glass is to cool a material from its liquid state quickly enough that
nucleation and growth of a crystalline phase do not happen. When the transition to the …

We analyze the collective dynamics of self-propelled particles in the large-density regime
where passive particles undergo a kinetic arrest to an amorphous glassy state. We capture …
