The exploration of the universe has recently entered a new era thanks to the multi-
messenger paradigm, characterized by a continuous increase in the quantity and quality of …

This article discusses the intimate relationship between quantum mechanics, information
theory, and relativity theory. Taken together these are the foundations of present-day …

This book is devoted to aspects of the foundations of quantum mechanics in which
probabilistic and statistical concepts play an essential role. The main part of the book …

The new edition provided the opportunity of adding a new chapter entitled" Principles and
Lessons of Quantum Physics". It was a tempting challenge to try to sharpen the points at …

PCT, Spin and Statistics, and All That is the classic summary of and introduction to the
achievements of Axiomatic Quantum Field Theory. This theory gives precise mathematical …

We show how the correlations of a quantum system with other quantum systems may cause
one of its observables to behave in a classical manner. In particular," reduction of the wave …

The theme of the present article concerns the information field. It is stated here that
information field may be discrete or continuous. Information field includes two types: natural …

Quantum mechanics is cast into a classical Hamiltonian form in terms of a symplectic
structure, not on the Hilbert space of state-vectors but on the more physically relevant infinite …

FJ Ynduráin's book on Quantum Chromodynamics has become a classic among advanced
textbooks. First published in 1983, and translated into Russian in 1986, it now sees its fourth …

We analyze a point-separation prescription for renormalizing the stress-energy operator T μ
ν of a quantum field in curved spacetime, based on the assumption that the expectation …
