How Continuous Symmetry Stabilizes the Ordered Phase of Polar Flocks
Omer Granek, Hugues Chaté, Yariv Kafri +3
We study the stability of the ordered phase of compressible polar flocks against the nucleation of counter-propagating droplets, using a combination of analytical theory, microscop…
Inclusions, Boundaries and Disorder in Scalar Active Matter
Omer Granek, Yariv Kafri, Mehran Kardar +3
Active systems are driven out of equilibrium by exchanging energy and momentum with their environment. This endows them with anomalous mechanical properties that we review in this…
Metastability of Discrete-Symmetry Flocks
Brieuc Benvegnen, Omer Granek, Sunghan Ro +6
We study the stability of the ordered phase of flocking models with a scalar order parameter. Using both the active Ising model and a hydrodynamic description, we show that droplet…
Defect turbulence in a dense suspension of polar, active swimmers
Navdeep Rana, Rayan Chatterjee, Sunghan Ro +3
We study the effects of inertia in dense suspensions of polar swimmers. The hydrodynamic velocity field and the polar order parameter field describe the dynamics of the suspension.…
Disordered boundaries destroy bulk phase separation in scalar active matter
Ydan Ben Dor, Sunghan Ro, Yariv Kafri +2
We show that disordered boundaries destroy bulk phase separation in scalar active systems in dimension . This is in strong contrast with the equilibrium case where boundar…
Play. Pause. Rewind. Measuring local entropy production and extractable work in active matter
Sunghan Ro, Buming Guo, Aaron Shih +5
Time-reversal symmetry breaking and entropy production are universal features of nonequilibrium phenomena. Despite its importance in the physics of active and living systems, the e…
Chiral Separation by Flows: The Role of Flow Symmetry and Dimensionality
Sunghan Ro, Juyeon Yi, Yong Woon Kim
Separation of enantiomers by flows is a promising chiral resolution method using cost-effective microfluidics. Notwithstanding a number of experimental and numerical studies, a fun…
