The algorithm can stabilize energy at a value less than one half of the energy gap between the two system states and is shown to be more effective for cooling than for heating. © 2021 Elsevier B.V., All rights reserved.eninfo:eu-repo/semantics/openAccessQuantum SystemSpeed GradientEnergy TransferSpectral DensityGradient Based AlgorithmQuantum SystemSystem StateQuantum OpticsConference Object10.1016/j.ifacol.2015.09.2262-s2.0-84992512773
