Heat capacity of a one-dimensional perturbed oscillator. C V /k B vs. reduced temperature \(t=k_{B} T /(\hbar \omega)\). The lower (upper) solid line is the result for the harmonic (perturbed) oscillator, i.e., λ=0(0.01). The dashed line is the numerical solution of the perturbed oscillator’s heat capacity
