Species interconversion of deformable particles yields transient phase separation
New Journal of PhysicsWe consider a dense assembly of repulsive particles whose fluctuating sizes are subject to an energetic landscape that defines three species: two distinct states of particles with a finite size, and point particles as an intermediate state between the ...

Rigid flocks, undulatory gaits, and chiral foldamers in a chemically active polymer
New Journal of PhysicsActive matter systems—such as a collection of active colloidal particles—operate far from equilibrium with complex inter-particle interactions that govern their collective dynamics. Predicting the collective dynamics of such systems may aid the design of

Active Matter Alters the Growth Dynamics of Coffee Rings
, 2018 How particles are deposited at the edge of evaporating droplets, i.e. the {\em coffee ring} effect, plays a crucial role in phenomena as diverse as thin-film deposition, self-assembly, and biofilm formation.

Crystallization and flow in active patch systems
, 2017 Based upon recent experiments in which Janus particles are made into active swimmers by illuminating them with laser light, we explore the effect of applying a light pattern on the sample, thereby creating activity inducing zones or active patches.

Noise and diffusion of a vibrated self-propelled granular particle
, 2017 Granular materials are an important physical realization of active matter. In vibration-fluidized granular matter, both diffusion and self-propulsion derive from the same collisional forcing, unlike many other active systems where there is a clean ...

New Journal of Physics, 2019 This paper studies the influence of orienting external fields on pattern formation, particularly mesoscale turbulence, in microswimmer suspensions. To this end, we apply a hydrodynamic theory that can be derived from a microscopic microswimmer model ...

, 2023 Many biological and synthetic systems out of equilibrium can be viewed as ratchets that rectify environmental noise through measurements and information processing, like in Maxwell's prototypical demon. These systems pose a challenge to standard approaches because they are better described in terms of decision-making protocols similar to computer ...

Roles of energy dissipation in a liquid-solid transition of out-of-equilibrium systems
, 2015 Self-organization of active matter as well as driven granular matter in non-equilibrium dynamical states has attracted considerable attention not only from the fundamental and application viewpoints but also as a model to understand the occurrence of ...

Exotic Charges, Multicomponent Dark Matter and Light Sterile Neutrinos
, 2013 Generating small sterile neutrino masses via the same seesaw mechanism that suppresses active neutrino masses requires a specific structure in the neutral fermion mass matrix.

Impact of eV-mass sterile neutrinos on neutrino-driven supernova outflows
, 2012 Motivated by recent hints for sterile neutrinos from the reactor anomaly, we study active-sterile conversions in a three-flavor scenario (2 active + 1 sterile families) for three different representative times during the neutrino-cooling evolution of the
