Query: Non-Equilibrium Currents in Stochastic Field Theories: a Geometric
  Insight   We introduce a new formalism to study nonequilibrium steady-state currents in
stochastic field theories. We show that generalizing the exterior derivative to
functional spaces allows identifying the subspaces in which the system
undergoes local rotations. In turn, this allows predicting the counterparts in
the real, physical space of these abstract probability currents. The results
are presented for the case of the Active Model B undergoing motility-induced
phase separation, which is known to be out of equilibrium but whose
steady-state currents had never been observed so far. We locate and measure
these currents and show that they manifest in real space as propagating modes,
localized at the interfaces between the gas and the liquid phases.
