One-dimensional marginal well-tempered target distribution (dynamic).

One-dimensional marginal well-tempered distribution [8] given by

\[ p(s_{k}) = \frac{e^{-(\beta/\gamma) F(s_{k})}} {\int ds_{k}\, e^{-(\beta/\gamma) F(s_{k})}} = \frac{[P_{0}(s_{k})]^{1/\gamma}} {\int ds_{k}\, [P_{0}(s_{k})]^{1/\gamma}} \]

where \(\gamma\) is a so-called bias factor and \(P_{0}(\mathbf{s})\) is the unbiased canonical distribution of the CVs. This target distribution thus correponds to a biased ensemble where, as compared to the unbiased one, the probability peaks have been broaden and the fluctations of the CVs are enhanced. The value of the bias factor \(\gamma\) determines by how much the fluctations are enhanced.
