      abstract     = {In a description of physical systems with Langevin
                      equations, interacting degrees of freedom are usually
                      coupled through symmetric parameter matrices. This coupling
                      symmetry is a consequence of time-reversal symmetry of the
                      involved conservative forces. If coupling parameters
                      fluctuate randomly, the resulting noise is called
                      multiplicative. For example, mechanical oscillators can be
                      coupled through a fluctuating, symmetric matrix of spring
                      “constants.” Such systems exhibit well-studied
                      instabilities. In this article, we study the complementary
                      case of antisymmetric, time-reversal symmetry-breaking
                      coupling that can be realized with Lorentz forces or various
                      gyrators. We consider the case in which these antisymmetric
                      couplings fluctuate. This type of multiplicative noise does
                      not lead to instabilities in the stationary state but
                      renormalizes the effective nonequilibrium friction.
                      Fluctuating Lorentz-force-like couplings also allow one to
                      control and rectify heat transfer. A noteworthy property of
                      this mechanism of producing asymmetric heat flux is that the
                      controlling couplings do not exchange energy with the
                      system.},
