... news: with higher energy than any previous collider, they could finally search the whole mass range for a Standard Model Higgs with a few years’ data. But would they find a Standard Model Higgs, or would they instead find the first hints that Nature is more complicated than our expectations? Most pa ...

Introduction to Modern Canonical Quantum General Relativity

... Canonical quantum general relativity is an attempt to define a mathematically rigorous, nonperturbative, background independent theory of Lorentzian quantum gravity in four spacetime dimensions in the continuum. As such it differs considerably from perturbative ansätze. It provides a unified theory ...

They exhibit various nonclassical properties as sub-Poissonian statistics, squeezing and oscillations in the photon-number distribution. Here we investigate other properties of these elds, as waiting-time and ph ...

History of quantum field theory

In particle physics, the history of quantum field theory starts with its creation by Paul Dirac, when he attempted to quantize the electromagnetic field in the late 1920s. Major advances in the theory were made in the 1950s, and led to the introduction of quantum electrodynamics (QED). QED was so successful and ""natural"" that efforts were made to use the same basic concepts for the other forces of nature. These efforts were successful in the application of gauge theory to the strong nuclear force and weak nuclear force, producing the modern standard model of particle physics. Efforts to describe gravity using the same techniques have, to date, failed. The study of quantum field theory is alive and flourishing, as are applications of this method to many physical problems. It remains one of the most vital areas of theoretical physics today, providing a common language to many branches of physics.
