      abstract     = {We perform a detailed study of the effect of finite bias
                      and magnetic field on the tunneling-induced decay of the
                      state of a quantum dot by applying a recently discovered
                      general duality [Phys. Rev. B 93, 81411 (2016)]. This
                      duality provides deep physical insight into the decay
                      dynamics of electronic open quantum systems with strong
                      Coulomb interaction. It associates the amplitudes of decay
                      eigenmodes of the actual system to the eigenmodes of a
                      so-called dual system with attractive interaction. Thereby,
                      it predicts many surprising features in the transient
                      transport and its dependence on experimental control
                      parameters: the attractive interaction of the dual model
                      shows up as sharp features in the amplitudes of measurable
                      time-dependent currents through the actual repulsive system.
                      In particular, for interacting quantum dots, the
                      time-dependent heat current exhibits a decay mode that
                      dissipates the interaction energy and that is tied to the
                      fermion parity of the system. We show that its decay
                      amplitude has an unexpected gate-voltage dependence that is
                      robust up to sizable bias voltages and then bifurcates,
                      reflecting that the Coulomb blockade is lifted in the dual
                      system. Furthermore, combining our duality relation with the
                      known Iche-duality, we derive new symmetry properties of the
                      decay rates as a function of magnetic field and gate
                      voltage. Finally, we quantify charge- and spin-mode mixing
                      due to the magnetic field using a single mixing parameter.},
