Digital Library of Periodicals of National Academy of Sciences of Ukraine| Резюме: | Kinetic equations describing short-time evolution of the electron-phonon
system are derived in non-Markovian Born approximation by the density
matrix method. The approach presented in the paper differs from earlier
schemes in that the interaction energy is treated as an independent state
parameter on the same footing as the electron and phonon distribution
functions. This introduces new correlation terms into the kinetic equations,
which ensure the energy conservation and the existence of the correct
equilibrium solution. An explicit expression for the time-dependent correlation energy is obtained. |
