Boltzmann occupation factors
WebAbstract: In this paper, the dependence of absorption power on the temperature in an end pumped Yb:YAG quasi-three level thin disk laser is calculated. Here, we have used the temperature-dependent form of Boltzmann occupation factors, absorption cross section and thermal conductivity of the Yb:YAG crystal. WebThe term Boltzmann entropy is also sometimes used to indicate entropies calculated based on the approximation that the overall probability can be factored into an identical separate term for each particle—i.e., assuming each particle has an identical independent probability distribution, and ignoring interactions and correlations between the …

WebThe rates of many physical processes are also determined by the Boltzmann factor. For a random particle, its thermal energy of a particle is a small multiple of the energy \(k T\). An increase in temperature results in more particles crossing the energy barrier characteristic of activation processes. If this is to occur, particles need to carry ... WebJun 11, 2014 · It is shown that the Boltzmann result, containing the correct transport scattering time instead of the electron lifetime determined by the Green function, can be recovered in problems with elastic and inelastic scattering at the lowest order of interaction.
