Reconsidering Relativistic Causality
I discuss the idea of relativistic causality, i.e. the requirement that causal processes or signals can propagate only within the light-cone. After briefly locating this requirement in the philosophy of causation, my main aim is to draw philosophers’ attention to the fact that it is subtle, indeed problematic, in relativistic quantum physics: there are scenarios in which it seems to fail. I con...
متن کاملDo Evanescent Modes Violate Relativistic Causality?
Time dependent experiments with evanescent modes (photonic tunneling) can be performed with high precision and at a macroscopic scale with microwaves in the range of meters or in the infrared regime in the range of centimeters. The infrared technology is the present day digital signal processing and transmission. Superluminal (faster than light) signal transmission by evanescent modes was shown...
متن کاملCausality in Relativistic Many Body Theory
Dirac sea effects are perhaps the most interesting characteristic of relativistic many body theory. In nuclear matter e.g. the effective mass of the nucleons and their coupling to the mesons undergo considerable corrections due to vacuum fluctuations [1], [2]. In addition, relativistic many body theory predicts strong corrections of the properties of hadrons at high nuclear matter densities. Un...
متن کاملRelativistic Causality and Quasi–Orthomodular Algebras
The concept of fractionability or decomposability in parts of a physical system has its mathematical counterpart in the lattice–theoretic concept of orthomodularity. Systems with a finite number of degrees of freedom can be decomposed in different ways, corresponding to different groupings of the degrees of freedom. The orthomodular structure of these simple systems is trivially manifest. The p...
متن کاملQuantum probability assignment limited by relativistic causality
Quantum theory has nonlocal correlations, which bothered Einstein, but found to satisfy relativistic causality. Correlation for a shared quantum state manifests itself, in the standard quantum framework, by joint probability distributions that can be obtained by applying state reduction and probability assignment that is called Born rule. Quantum correlations, which show nonlocality when the sh...
