• matrix can be split into an “equilibrium” contribution, γs,eq, and a purely nonequilibrium contribution γs,ne, as γs = γs,eq + γs,ne. We first treat γs,eq. By the calculations given in Supporting Information File 1, Section B, we obtain where we have used ∑α′Πα′ = 1, S†S = 1, and Equation 34 in the last

• express γs,ne in terms of S-matrix quantities, we have to make use of the A-matrix defined in Equation 33. Again the details are given in Supporting Information File 1, Section B, where we find, after lengthy manipulations, that This quantity vanishes in equilibrium, as can be shown by using the

• out-of-equilibrium situations. This is due to a negative contribution of γs,ne to the total damping. This is visualized in Figure 4b and Figure 4d. Negative damping is possible when both dot levels are inside the conduction window, restricting the region in X over which negative damping can occur
