  • Algebraic Renormalization deals with the perturbative renormalization of quantum Lagrangian field models with local or rigid symmetries. (scholarpedia.org)

  • In Quantum Field Theory, this means giving first a set of local fields and their transformation laws under the action of the group of the symmetries of the system. (scholarpedia.org)
  • In quantum field theory, the symmetries are expressed by a set of relations between the Green functions, called Ward identities (WI). (scholarpedia.org)
  • Much has been learned about those special sectors of M-theory which can be described by string theories or supergravity theories, and of the remarkable duality symmetries that relate such sectors, but much of M-theory remains a mystery. (newton.ac.uk)
  • In QED and other quantum field theories, special calculation techniques known as Feynman diagrams are used to systematically sum the power series terms. (wikipedia.org)
  • This allows the calculation of spectra in regions that are problematic in regular response theory. (lu.se)
  • Wfn or Wfx files contain information about the wavefunction and can be used to read information from a previous quantum chemical calculation. (lu.se)
  • In short, the aim is to prove that the full perturbative quantum theory has the same invariance properties as the classical theory. (scholarpedia.org)
  • The algebraic renormalization scheme is based on general theorems of perturbative quantum field theory, such as the Power Counting Theorem and the Quantum Action Principle . (scholarpedia.org)

  • The properties of quantum evaporation are being studied, including the difficult problem of measuring the quantum efficiency of the evaporation. (ex.ac.uk)
  • second, to give a detailed account of how theories without a spacetime can be interpreted, and so of how they can be understood. (pitt.edu)
  • In order to do so, we of course need an account of what is meant by a theory `without a spacetime': which we also provide in this paper. (pitt.edu)
  • This unique experimental platform should be capable of enabling quantum control over the center-of-mass motion of the levitated particle. (chalmers.se)

  • I examine the relationship of solutions in constructive field theory to both axiomatic and Lagrangian quantum field theory (QFT). (pitt.edu)
  • Constructive field theory, in incorporating ingredients from both axiomatic and Lagrangian QFT, clarifies existing disputes about which parts of QFT are philosophically relevant and how rigor relates to these disputes. (pitt.edu)
  • One has then to establish the evolution equations - the field equations - of the theory, in such a manner that they are covariant under the symmetry transformations. (scholarpedia.org)
