    The Meaning of the Interaction-Free Measurements
    Foundations of Physics 33 (3): 491-510. 2003.
    Interaction-free measurements introduced by Elitzur and Vaidman [Found. Phys. 23, 987 (1993)] allow finding infinitely fragile objects without destroying them. Many experiments have been successfully performed showing that indeed, the original scheme and its modifications lead to reduction of the disturbance of the observed systems. However, there is a controversy about the validity of the term “interaction-free” for these experiments. Broad variety of such experiments are reviewed and the meani…Read more

    On schizophrenic experiences of the neutron or why we should believe in the many‐worlds interpretation of quantum theory
    International Studies in the Philosophy of Science 12 (3). 1990.
    This is a philosophical paper in favor of the many-worlds interpretation of quantum theory. The necessity of introducing many worlds is explained by analyzing a neutron interference experiment. The concept of the “measure of existence of a world” is introduced and some difficulties with the issue of probability in the framework of the MWI are resolved

    Byrne and Hall on Everett and Chalmers
    It is argued that the criticism of Byrne and Hall of the argument of Chalmers in favor of the Everett-style interpretation is incorrect.

    Sleeping Beauty in Quantumland
    It is argued that thirder resolution of the Lewis - Elga controversy about Sleeping Beauty is more clear when the coin toss is replaced by a quantum measurement and the analysis is performed in the framework of the Many-Worlds Interpretation.

    Many-worlds interpretation of quantum mechanics
    Stanford Encyclopedia of Philosophy. 2008.
    The Many-Worlds Interpretation (MWI) is an approach to quantum mechanics according to which, in addition to the world we are aware of directly, there are many other similar worlds which exist in parallel at the same space and time. The existence of the other worlds makes it possible to remove randomness and action at a distance from quantum theory and thus from all physics

    The measure of existence of a quantum world and the Sleeping Beauty Problem
    with Berry Groisman and Na'ama Hallakoun
    Analysis 73 (4): 695-706. 2013.
    Next SectionAn attempt to resolve the controversy regarding the solution of the Sleeping Beauty Problem in the framework of the Many-Worlds Interpretation led to a new controversy regarding the Quantum Sleeping Beauty Problem. We apply the concept of a measure of existence of a world and reach the solution known as ‘thirder’ solution which differs from Peter Lewis’s ‘halfer’ assertion. We argue that this method provides a simple and powerful tool for analysing rational decision theory problems
