摘要: We derive a general formula, using Fermi’s golden rule, for the multiphonon relaxation rate two‐level system coupled off‐diagonally to bath of phonons. Our result is valid any scalar form system‐bath interaction potential. With our we analyze experimental data involving energy gap and temperature dependence electronic rates rare‐earth ions in YAlO3.
