Wigner's 1932 quasi-probability Distribution Function in phase-space, his first paper in English, is a special (Weyl) representation of the density matrix. It has been useful in describing quantum flows in semiclassical limits; quantum optics; nuclear physics; decoherence (eg, quantum computing); quantum chaos; "Welcher Weg" puzzles. It is also of great importance in signal processing...

The linearity of quantum mechanics leads to the superposition principle and interference,
entailing entanglement, and the enigmatic phenomena of Schrődinger's Cat and Wigner's
Friend.
We introduce an action principle for a class of integer valued cellular automata and obtain
Hamiltonian equations of motion. Employing sampling theory, these discrete deterministic
equations are invertibly...

We consider the special and general relativistic extensions of the action principle behind the Schrödinger equation distinguishing classical and quantum contributions via the use of Madelung variables for the wave function field. Postulating a particular quantum correction to the source term in the classical Einstein equation we identify the conformal content of the above action and obtain...

Traditional geometry employs idealized concepts like that of a point or a curve, the
operational definition of which relies on the availability of classical point particles as
probes. Real, physical objects are quantum in nature though, leading us to consider
the implications of using realistic probes in defining an effective spacetime geometry.
As an example, we consider de Sitter...
