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

Species interconversion of deformable particles yields transient phase separation

New Journal of Physics
We 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 ...

Dynamic density shaping of photokinetic E. coli

eLife, 2018
Many motile microorganisms react to environmental light cues with a variety of motility responses guiding cells towards better conditions for survival and growth.

Rigid flocks, undulatory gaits, and chiral foldamers in a chemically active polymer

New Journal of Physics
Active 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

Noisy active matter

Noise threads every scale of the natural world. Once dismissed as mere background hiss, it is now recognized as both a currency of information and a source of order in systems driven far from equilibrium. From nanometer-scale motor proteins to meter-scale bird flocks, active collectives harness noise to break symmetry, explore decision landscapes, and ...

Entropy production rate in thermodynamically consistent flocks

New Journal of Physics
We study the entropy production rate (EPR) of aligning self-propelled particles which undergo a flocking transition into a state of polarized collective motion.

Mean first passage time of active Brownian particles in two dimensions

New Journal of Physics
The mean first passage time (MFPT) is a key metric for understanding transport, search, and escape processes in stochastic systems. While well characterized for passive Brownian particles, its behavior in active systems—such as active Brownian particles (

Flocking transition in phoretically interacting active particles with pinning disorder

New Journal of Physics
Recent studies in the collective behavior of active colloids have shown that a global polar order may emerge due to long-ranged chemo-repulsive interactions between them.
