Há 1 dia · where the quantization of the Yang-Mills Equations is carried out and the axioms of Constructive Quantum Field Theory, the Osterwalder-Schrader’s ones and hence the Wightman’s ones are verified, and the existence of a positive mass gap proven. Gauge invariance is treated as well. Section 4 is
Há 6 dias · The path integral formulation of quantum field theory represents the transition amplitude (corresponding to the classical correlation function) as a weighted sum of all possible histories of the system from the initial to the final state.

Há 2 dias · In a few recent manuscripts, we used the affine connection to introduce two massless scalar fields in the Einstein-Palatini action. These fields lead to non-metricity. In this article, we will discuss the significance of these fields in inflation and dark energy. We will construct a Lagrangian formalism to include these scalar fields in a theory of gravity coupled with ordinary matter and ...
Há 2 dias · In quantum mechanics, perturbation theory is a set of approximation schemes directly related to mathematical perturbation for describing a complicated quantum system in terms of a simpler one.
Há 2 dias · He was the first to develop quantum field theory, which underlies all theoretical work on sub-atomic or "elementary" particles today, work that is fundamental to our understanding of the forces of nature.
Há 2 dias · An international team of scientists from China and the U.S. has developed a scalable protocol for high-fidelity quantum state transfer (QST) in a 36-qubit superconducting quantum circuit.
