... Dulong and Petit (1819) [2]. However, it is well known that the experimental heat capacity decreases when temperature decreases and vanishes at 0K. In addition, due to the quantum fluctuations according to the Heisenberg uncertainty principle, the energy of the system at 0K called “zero-point energy ...
