“…These peaks-not present at T = 0 [50,51]-arise from thermally activated transitions to states with additional phonons excited, and are also visible in figures 11 and 13. While for WC (λ = 0.1, figure 11), the maximum of these features is almost exactly located at |ω − µ| = ω 0 , it moves to |ω − µ| ≈ 1.25ω 0 for IC (λ = 1, figure 15), and finally to |ω − µ| ≈ 2.5ω 0 for SC (λ = 2, figure 13).…”
