Quantum mechanics
Quantum mechanics, also known as quantum physics or quantum theory, is a branch of physics providing a mathematical description of much of the dual particle-like and wave-like behavior and interactions of energy and matter. It departs from classical mechanics primarily at the atomic and subatomic...

, starting in 1946, he was professor of theoretical physics at the University of Warsaw until 1960.

While at Munich, Rubinowicz published contributions to radiation theory and to three of Sommerfeld’s major interests, i.e., Sommerfeld’s extension of Bohr’s theory of the atom and both mathematical physics and diffraction theory; he carried these topical interests throughout his career. He eventually published books based on his mathematical physics interests as well as diffraction theory: his work on the polynomial method of solving eigenvalue problems in quantum mechanics was described in "Sommerfeldsche Polynommethode" and his work on diffraction theory, was published in "Die Beugungswelle in der Kirchhoffschen Theorie der Beugung".

Also while at Munich, Rubinowicz transformed the Kirchhoff diffraction integral into what has become known as the Rubinowicz representation (also known as the Maggie-Rubinowicz representation) for which scalar and electromagnetic fields are interpreted as a transformation of a surface integral into a line integral – an independent and slightly different derivation from that done in 1888 by G. A. Maggi, one of Gustav Kirchhoff's students in Berlin. Rubinowicz’s form of the representation, as opposed to Maggi’s, is now more commonly accepted.
