Second Quantization and Lorentz Invariance
The problem of Lorentz invariance is treated in the conventional quantum field theory as follows: I) Field variables are transformed as classical quantities. II) Next, the procedure of the second quantization is performed in the new coordinate system. Then the commutation relations are retained to be invariant. However, as Wignerl) has pointed out, the invariance of the commutation relations do...
متن کاملLorentz Invariance on Trial
experiment was surprising and difficult to explain in terms of then prevalent physics concepts. It required a fundamental change in the notions of space and time and was finally explained, almost 20 years later, by Albert Einstein’s special theory of relativity. (See the May 1987 special issue of PHYSICS TODAY devoted to the centennial of the experiment.) Special relativity postulates that all ...
متن کاملInstantons, Scale Invariance and Lorentz Invariance in Matrix Theory
In this paper we consider features of graviton scattering in Matrix theory compactified on a 2-torus. The features which interest us can only be determined by nonperturbative effects in the corresponding 2+1 dimensional super Yang Mills theory. We show that the superconformal symmetry of strongly coupled Super Yang Mills Theory in 2 + 1 dimensions almost determines low energy, large impact para...
متن کاملLorentz Invariance of Neutrino Oscillations
It is shown that, in spite of the appearances, the standard expression for the oscillation probability of ultrarelativistic neutrinos is Lorentz invariant. Flavor is the quantum number that distinguishes the different types of quarks and leptons. It is a Lorentz-invariant quantity. For example, an electron is seen as an electron by any observer, never as a muon. Therefore, the probability of fl...
متن کاملModern Tests of Lorentz Invariance
Motivated by ideas about quantum gravity, a tremendous amount of effort over the past decade has gone into testing Lorentz invariance in various regimes. This review summarizes both the theoretical frameworks for tests of Lorentz invariance and experimental advances that have made new high precision tests possible. The current constraints on Lorentz violating effects from both terrestrial exper...
