Space / time non - commutativity and causality
Field theories based on non-commutative spacetimes exhibit very distinctive non-local effects which mix the ultraviolet with the infrared in bizarre ways. In particular if the time coordinate is involved in the non-commutativity the theory seems to be seriously acausal and inconsistent with conventional hamiltonian evolution. To illustrate these effects we study the scattering of wave packets i...
متن کاملLocal Causality, Probability and Explanation
In papers published in the 25 years following his famous 1964 proof John Bell refined and reformulated his views on locality and causality. Although his formulations of local causality were in terms of probability, he had little to say about that notion. But assumptions about probability are implicit in his arguments and conclusions. Probability does not conform to these assumptions when quantu...
متن کاملCommutativity in the Algorithmic Lovász Local Lemma
Recently, Achlioptas and Iliopoulos [1] proposed a new “Random Walk” framework for finding objects that avoid “bad features”, or “flaws”. It extends the Moser-Tardos resampling algorithm [12] to more general discrete spaces. At each step the method picks a flaw present in the current state and “resamples” it. However, it is less flexible than the Moser-Tardos method since [1] requires a specifi...
متن کاملRe-thinking local causality
There is widespread belief in a tension between quantum theory and special relativity, motivated by the idea that quantum theory violates J. S. Bell’s criterion of local causality, which is meant to implement the causal structure of relativistic space-time. This paper argues that if one takes the essential intuitive idea behind local causality to be that probabilities in a locally causal theory...
متن کاملNon-commutativity and Local Indistinguishability of Quantum States
We study the local indistinguishability problem of quantum states. By introducing an easily calculated quantity, non-commutativity, we present an criterion which is both necessary and sufficient for the local indistinguishability of a complete set of pure orthogonal product states. A constructive distinguishing procedure to obtain the concrete local measurements and classical communications is ...
