Negative absolute temperatures are a fascinating and counterintuitive concept. 🌡️❄️
Negative temperatures do not occur in classical systems; they are seen only in certain quantum systems.
We've used the Boltzmann distribution framework to explain temperature and thermal distribution because it provides an easy-to-understand basis and avoids going into complexities. However, the distribution will be based on Bose-Einstein or Fermi-Dirac distributions in quantum systems with negative temperatures. The discussion of negative temperatures in terms of the Boltzmann distribution is still relevant because it provides a simplified framework for understanding the concept of negative temperatures.
