In active matter systems, individual constituents convert energy into non-conservative forces
or motion at the microscale, leading to morphological features and transport properties that …

Liquid crystals (LCs) are ubiquitous in display technologies. The orientational ordering in the
nematic phase of LCs gives rise to structural anisotropy, the ability to form topological …

Active materials are capable of converting free energy into mechanical work to produce
autonomous motion, and exhibit striking collective dynamics that biology relies on for …

The past decade has witnessed a rapid growth in understanding of the pivotal roles of
mechanical stresses and physical forces in cell biology. As a result, an integrated view of …

Tissues acquire function and shape via differentiation and morphogenesis. Both processes
are driven by coordinating cellular forces and shapes at the tissue scale, but general …

Microswimmers exhibit an intriguing, highly-dynamic collective motion with large-scale
swirling and streaming patterns, denoted as active turbulence–reminiscent of classical high …

Biological tissues are composed of various cell types working cooperatively to perform their
respective function within organs and the whole body. During development, embryogenesis …

Coupling between flows and material properties imbues rheological matter with its wide-
ranging applicability, hence the excitement for harnessing the rheology of active fluids for …

Topological defects play a prominent role in the physics of two-dimensional materials. When
driven out of equilibrium in active nematics, disclinations can acquire spontaneous self …

The physics of active liquid crystals is mostly governed by the interplay between elastic
forces that align their constituents, and active stresses that destabilize the order with …
