Polymer-Chain Configurations in Active and Passive Baths
Caleb J. Anderson, Guillaume Briand, Olivier Dauchot +1
The configurations taken by polymers embedded in out-of-equilibrium baths may have broad effects in a variety of biological systems. As such, they have attracted considerable inter…
Physically-informed data-driven modeling of active nematics
Matthew Golden, Roman Grigoriev, Jyothishraj Nambisan +1
A continuum description is essential for understanding a variety of collective phenomena in active matter. However, building quantitative continuum models of active matter from fir…
Reverse Janssen effect in narrow granular columns
Shivam Mahajan, Michael Tennenbaum, Sudhir N. Pathak +6
When grains are added to a cylinder, the weight at the bottom is smaller than the total weight of the column, which is partially supported by the lateral walls through wall/grain f…
Orientational correlations in active and passive nematic defects
D. J. G. Pearce, J. Nambisan, P. W. Ellis +2
We investigate the emergence of orientational order among +1/2 disclinations in active nematic liquid crystals. Using a combination of theoretical and experimental methods, we show…
Swelling thermodynamics and phase transitions of polymer gels
Michael S. Dimitriyev, Ya-Wen Chang, Paul M. Goldbart +1
We present a pedagogical review of the swelling thermodynamics and phase transitions of polymer gels. In particular, we discuss how features of the volume phase transition of the g…
Extreme thermodynamics with polymer gel tori: harnessing thermodynamic instabilities to induce large-scale deformations
Ya-Wen Chang, Michael S. Dimitriyev, Anton Souslov +5
When a swollen, thermoresponsive polymer gel is heated in a solvent bath, it expels solvent and deswells. When this heating is slow, deswelling proceeds homogeneously, as observed…
Transition from turbulent to coherent flows in confined three-dimensional active fluids
Kun-Ta Wu, Jean Bernard Hishamunda, Daniel T. N. Chen +5
Transport of fluid through a pipe is essential for the operation of macroscale machines and microfluidic devices. Conventional fluids only flow in response to external pressure. We…
Spherical nematics with a threefold valence
Vinzenz Koning, Teresa Lopez-Leon, Alexandre Darmon +2
We present a theoretical study of the energetics of thin nematic shells with two charge one-half defects and one charge-one defect. We determine the optimal arrangement: the defect…
Impact of single-particle compressibility on the fluid-solid phase transition for ionic microgel suspensions
M. Pelaez-Fernandez, Anton Souslov, L. A. Lyon +2
We study ionic microgel suspensions composed of swollen particles for various single-particle stiffnesses. We measure the osmotic pressure of these suspensions and show that it…
Stable nematic droplets with handles
E. Pairam, J. Vallamkondu, V. Koning +5
We stabilize nematic droplets with handles against surface-tension-driven instabilities using a yield-stress material as outer fluid and study the complex nematic textures and defe…
Corrugated interfaces in multiphase core-annular flow
Ho Cheung Shum, Alban Sauret, Alberto Fernandez-nieves +2
Microfluidic devices can be used to produce highly controlled and monodisperse double or multiple emulsions. The presence of inner drops inside a jet of the middle phase introduces…
