Stephens' constant

Stephens' constant, often denoted by \( \sigma \), is a physical constant that arises in the context of quantum mechanics and statistical physics. It is specifically associated with the calculation of the density of states for quantum particles in a certain system. However, it is not a universally recognized term like Planck's constant or Boltzmann constant. In many contexts, the term might refer to properties or constants in specific studies related to statistical distributions.
