In current quantum field theory, causality is typically defined by the vanishing of field commutators for spacelike separations. Two researchers at the University of Massachusetts and Universidade ...

A new model extends the definition of causality to quantum-mechanical systems. Mathematical models for deducing cause-effect relationships from statistical data have been successful in diverse areas ...

Although the laws of physics explain much of the world around us, we still do not have a realistic description of causality in truly complex hierarchical structures. The atomic theory of matter and ...

Quantum space and time Physicists have developed no-go theorems that limit quantum processes in space–time causality. (Courtesy: iStock/piranka) Physicists have developed a new theoretical framework ...

A deeply rooted concept in everyday life is causality; the idea that events in the present are caused by events in the past and, in turn, act as causes for what happens in the future. Physicists from ...

You drop a cup and it smashes. I flick a light switch and the bulb glows. Effect follows cause – it is a hard-and-fast rule of the universe. Except, perhaps, at a fundamental level. Because when we ...

Whether a quantum object behaves like a wave or like a particle depends (according to the Copenhagen interpretation) on the choice of measurement apparatus used for observing the system, and therefore ...

Quantum mechanics wreaks even more havoc with conventional ideas of causality than some have suspected – according to a team of researchers based in Australia, with collaborators in Scotland and ...

Faster-than-light particles have spent decades in physics as both temptation and warning. They offered a way to test the limits of Einstein’s relativity, but they also seemed to wreck the basic order ...
