With a clever experiment, physicists have shown that in a one-dimensional quantum system, the initially complex distribution of vibrations or phonons can change over time into a simple Gaussian bell ...

SPOTTING A TAIL Some models assume that financial data follow a typical bell curve (black), with data points clustered around an average and then tapering off quickly to either side. But a handful of ...

A bell curve is a graph used to visualize the distribution of a set of chosen values across a specified group that tend to have central, normal values that peak, with low and high extremes tapering ...

Quantum physics allows to make statements about the behaviour of a wide variety of many-particle systems at the atomic level, from salt crystals to neutron stars. In quantum systems, many parameters ...
