In classical statistical physics, entropy can be defined either as Boltzmann entropy or Gibbs entropy. In quantum statistical physics we have von Neumann entropy, which is a quantum analog of Gibbs entropy. Is there a quantum analog of Boltzmann entropy?

We aim to provide a community for students, scientists, educators or hobbyists to learn and discuss science as it is currently generally understood and practiced by the professional scientific community.

Our main focus is physics, but we also cater to other STEM fields including engineering, chemistry, biology, mathematics, etc.

STEM homework help for students is available, as well as academic and career guidance.
