Active particles in moving traps: minimum work protocols and information efficiency of work extraction
Janik Schüttler, Rosalba Garcia-Millan, Michael E. Cates +1
We revisit the elementary problem of moving a particle in a harmonic trap in finite time with minimal work cost, and extend it to the case of an active particle. By comparing the G…

Optimal closed-loop control of active particles and a minimal information engine
Rosalba Garcia-Millan, Janik Schüttler, Michael E. Cates +1
We study the elementary problem of moving an active particle by a trap with minimum work input. We show analytically that (open-loop) optimal protocols are not affected by activity…

Effects of phase separation on extinction times in population models
Janik Schüttler, Robert L. Jack, Michael E. Cates
We study the effect of phase separating diffusive dynamics on the mean time to extinction in several reaction-diffusion models with slow reactions. We consider a continuum theory s…
