| Summary: | The mean numbers and the fluctuations for phonons in the Debye model of solid are calculated. When the temperatures are higher and lower in comparison with the characteristic one determined by the Debye cutoff frequency, the mean numbers are proportional to the temperature and temperature cubed, respectively, meanwhile, the fluctuations are proportional to the temperature squared and temperature cubed, respectively. |
