We consider the nearest-neighbour simple exclusion process on the one-dimensional discrete torus
$\mathbb{T}_N=\mathbb{Z}/N\mathbb{Z}$
, with random rates
$c_N=\{c_{x,N}\colon x \in \mathbb{T}_N\}$
defined in terms of a homogeneous Poisson process on
$\mathbb{R}$
with intensity
$\lambda$
. Given a realization of the Poisson process, the jump rate along the edge
$\{x,x+1\}$
is 1 if there is not any Poisson mark in
$ (x,x+1) $
; otherwise, it is
$\lambda/N,\, \lambda \in( 0,1]$
. The density profile of this process with initial measure associated to an initial profile
$\rho_0\colon \mathbb{R}
\rightarrow [0,1]$
, evolves as the solution of a bounded diffusion random equation. This result follows from an appropriate quenched hydrodynamic limit. If
$\lambda=1$
then
$\rho$
is discontinuous at each Poisson mark with passage through the slow bonds, otherwise the conductance at the slow bonds decreases meaning no passage through the slow bonds in the continuum. The main results are concerned with upper and lower quenched and annealed bounds of
$T_j$
, where
$T_j$
is the first displacement time of a tagged particle in a stochastic cluster of size j (the cluster is defined via specific macroscopic density profiles). It is possible to observe that when time t grows, then
$\mathbb{P}\{T_j \geq t\}$
decays quadratically in both the upper and lower bounds, and falls as slow as the presence of more Poisson marks neighbouring the tagged particle, as expected.
