Lorentz covariance of three - dimensional equations
We show how the invariance under the charge conjugation and CPT symmetry, present in the Bethe-Salpeter equation, is lost in the reduction to certain relativistic three-dimensional equations. This in particular leads to the breakdown of the standard Lorentz structure and renormalization procedures for the resulting single-particle propagators. We formulate the equal-time approximation of the Be...
متن کاملLorentz covariance of the canonical perfect lens
The electromagnetic properties of classical vacuum (i.e., empty space) are characterized by its permittivity ǫ0 = 8.854 × 10 −12 F m and permeability μ0 = 4π × 10 −7 H m. In contrast, anti–vacuum has permittivity −ǫ0 and permeability −μ0 [1]. The perfect lens, as conceptualized by Pendry [2], consists of a slab of anti–vacuum sandwiched by two slabs of vacuum. While this perfect lens is an idea...
متن کاملOn the meaning of Lorentz covariance
In classical mechanics, Galilean covariance and the principle of relativity are completely equivalent and hold for all possible dynamical processes. In contrast, in relativistic physics the situation is much more complex. It will be shown that Lorentz covariance and the principle of relativity are not completely equivalent. The reason is that the principle of relativity actually only holds for ...

متن کاملIs the concept of quantum probability consistent with Lorentz covariance?
Lorentz-covariant harmonic oscillator wave functions are constructed from the Lorentz-invariant oscillator differential equation of Feynman, Kislinger, and Ravndal for a two-body bound state. The wave functions are not invariant but covariant. As the differential equation contains the time-separation variable, the wave functions contain the same time-separation variable which does not exist in ...
