Reeh-Schlieder defeats Newton-Wigner: On alternative localization schemes in relativistic quantum field theory

Many of the "counterintuitive" features of relativistic quantum field theor y have their formal root in the Reeh-Schlieder theorem, which in particular entails that local operations applied to the vacuum state can produce any state of the entire field, it is of great interest then that I. E. Segal an d, more recently, G. Fleming tin a paper entitled "Reeh-Schlieder meets New ton-Wigner") have proposed an alternative "Newton-Wigner" localization sche me that avoids the Reeh-Schlieder theorem. In this paper, I reconstruct the Newton-Wigner localization scheme and clarify the limited extent to which it avoids the counterintuitive consequences of the Reeh-Schlieder theorem. I also argue that there is no coherent interpretation of the Newton-Wigner localization scheme that renders it free from act-outcome correlations at s pacelike separation.
