  We investigate emergence of spontaneous filtering of Brownian motion in
higher dimensional space by many--body structures of symmetry broken dimer.
Interacting dimer form structures which eventually restrict rotational degrees
of freedom of individual constituents resulting in spontaneous emergence of
collective transport. In this phenomenon, interaction and broken structural
symmetry play cooperatively in emergence of collective transport out of thermal
fluctuations. As a general phenomenon, spontaneous filtering of Brownian
fluctuation might play an important role in the structural transition of
complex molecules on top of what is known in terms of Kramers--rate process.
This could also be a missing link to completely understand basics of
bio--polymers' folding transitions (protein folding) where structure might
encode motion in phase space.
