Query: Dynamics of active run and tumble and passive particles in binary
  mixture   We study a binary mixture of disk-shaped {\it active run and tumble }
particles (${ARNPs}$) and passive particles on a two-dimensional substrate.
Both types of particles are athermal. The particles interact through the soft
repulsive potential. The activity of $ARNPs$ is controlled by tuning their
tumbling rate. The system is studied for various sizes of passive particles
keeping size of $ARNPs$ fixed. Hence the variables are, size ratio (S) of
passive particles and $ARNPs$, and activity of $ARNPs$ is $v$. The
characterstics dynamics of both $ARNPs$ and passive particles show a crossover
from early time ballistic to later time diffusive. Furthermore, we observed
that passive particles dynamics changes from diffusive to subdiffusive with
respect to their size. Moreover, late time effective diffusivity $D_{eff}$ of
passive particles decreases with increasing their size as in the corresponding
equilibrium Stokes systems. We calculated the effective temperatures, using
$D_{eff}$, $T_{a,eff}(\Delta)$ and also using speed distribution $T_{a,eff}(v)$
and compared them. The both $T_{a,eff}(\Delta)$ and $T_{a,eff}(v)$ increases
linearly with activity and are in agreement with each other. Hence we can say
that an effective equilibrium can be establish in such binary mixture. Our
study can be useful to study the various biological systems like; dynamics of
passive organels in cytoplasm, colloids etc.
