Entropy, once seen as a measure of disorder in physical systems, is now understood as a reflection of our ignorance and knowledge limitations. This evolving perspective links entropy to information theory and challenges traditional views of objectivity in science.
The article discusses a phenomenon known as the "Dynamic Quantum Cheshire Cat Effect", which is a type of quantum effect that allows physical properties to be separated from the objects to which they belong. The authors show that this effect can be generalized to dynamical settings, where the property that is separated from the particle can propagate in space and lead to a flux of conserved quantity.
