摘要: Abstract Although many elegant formulations of the phonon assisted tunneling problem have been given, calculation relaxation time itself always has based on “golden rule”, which requires artifice a fictitious static field. In this communication is given by means linear response theory, unitary transformations and an application Bogoliubov inequality. The field no longer required.
