The Facets of Relativistic Quantum Field Theory1
... the phenomena are Renormalized Perturbation Theory and Lattice Regularization, especially of a gauge theory, both approaches involving a concrete dynamical evolution. Each has its own specific inner concept of the relation between the quantized fields and the particles, which are more or less connec ...

Beating the Standard Quantum Limit
... achieves good precision only for small values of ϕ, other schemes exist that show the same high sensitivity for all values of this parameter [14]. Many quantum procedures that achieve the same 1/N sensitivity have been proposed that do not make explicit use of entangled inputs. For example, one can ...

Moreover, in the case of the heavy radioactive atoms we have a great variety of quantitative data with which to test the validity of any working theory. The simple theory of the origin of the a-rays which I shall outline in this ...
