ABSTRACT | We study a Brownian particle passively driven by a field obeying the noisy Burgers equation.
We demonstrate that the system exhibits replica symmetry breaking in the path ensemble with
the initial position of the particle being fixed. The key step of the proof is that the path ensemble
with a modified boundary condition can be exactly mapped to the canonical ensemble of
