Research

Ruskai's research focuses on mathematics applicable to quantum mechanics. In 1972 she and Elliot Lieb proved the
Strong Subadditivity of Quantum Entropy In quantum information theory, strong subadditivity of quantum entropy (SSA) is the relation among the von Neumann entropies of various quantum subsystems of a larger quantum system consisting of three subsystems (or of one quantum system with thre ...

theory) relies". In 1981 she gave the first proof that an atom can have only a maximum number of electrons bound to it regardless of the charge of its nucleus.
