Rectified rotational dynamics of mobile inclusions in two-dimensional active nematics

S Ray, J Zhang, Z Dogic - Physical Review Letters, 2023 - APS
We investigate the dynamics of mobile inclusions embedded in 2D active nematics. The
interplay between the inclusion shape, boundary-induced nematic order, and autonomous …

transformations of energy that drive diverse functions. Quantifying their irreversibility, as …

Theoretical limits of energy extraction in active fluids

S Shadkhoo, M Thomson - Physical Review Research, 2024 - APS
Active materials form a class of far-from-equilibrium systems that are driven internally and
exhibit self-organization, which can be harnessed to perform mechanical work. Inspired by …
