Secret History

In 1948 an official ‘Transfer Committee’ was appointed by the Israeli Cabinet to plan the Palestinian refugees' resettlement in the Arab states. Apart from doing everything possible to reduce the Arab population in Israel, the Transfer Committee sought to amplify and consolidate the demographic transformation of Palestine by: preventing the Palestinian refugees from returning to their homes; the destruction of Arab villages; settlement of Jews in Arab villages and towns; and launching a propaganda campaign to discourage Arab return. One of the Transfer Committee's initiatives was to invite Dr Joseph Schechtman, a right-wing Zionist Revisionist leader and expert on ‘population transfer’, to join its efforts. In 1952 Schechtman published a propagandists work entitled The Arab Refugee Problem. Since then Schechtman would become the single most influential propagator of the Zionist myth of ‘voluntary’ exodus in 1948. This article examines the leading role played by Schechtman in promoting Israeli propaganda and politics of denial. Relying on newly-discovered Israeli archival documents, the article deals with little known and new aspects of the secret history of the post-1948 period.

During the STIRAP process, the intermediate levels will have notable population which is detrimental if these levels could decay to other levels through spontaneous emission. Here, we propose a novel method which could reduce the intermediate level population during the STIRAP process. A complete population transfer could be achieved in this modified STIRAP even if the intermediate level could decay to other levels.

Abstract We use optimal control theory to show that for a closed Λ-system where the excited intermediate level decays to the lower levels with a common large rate, the optimal scheme for population transfer between the lower levels is actually optical pumping. In order to obtain this result we exploit the large decay rate to eliminate adiabatically the weakly coupled excited state, then perform a transformation to the basis comprised of the dark and bright states, and finally apply optimal control to this transformed system. Subsequently, we confirm the optimality of the optical pumping scheme for the original closed Λ-system using numerical optimal control. We also demonstrate numerically that optical pumping remains optimal when the decay rate to the target state is larger than that to the initial state or the two rates are not very different from each other. The present work is expected to find application in various tasks of quantum information processing, where such systems are encountered
