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.

Adiabatic Dynamics

Only very recently, rescaling time has been recognized as a way to achieve adiabatic dynamics in fast processes. The advantage of time-rescaling over other shortcuts to adiabaticity is that it does not depend on the eigenspectrum and eigenstates of the Hamiltonian. However, time-rescaling requires that the original dynamics are adiabatic, and in the rescaled time frame, the Hamiltonian exhibits non-trivial time-dependence. In this work, we show how time-rescaling can be applied to Dirac dynamics, and we show that all time-dependence can be absorbed into the effective potentials through a judiciously chosen unitary transformation. This is demonstrated for two experimentally relevant scenarios, namely for ion traps and adiabatic creation of Weyl points.

Stimulated Raman

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.
