Query: Generalized Elastic Model: Fractional Langevin Description, Fluctuation
  Relation, and Linear Response   The Generalized Elastic Model is a linear stochastic model which accounts for
the behaviour of many physical systems in nature, ranging from polymeric chains
to single-file systems. If an external perturbation is exerted \emph{only} on a
single point $\vec{x}^\star$ (\emph{tagged probe}), it propagates throughout
the entire system. Within the fractional Langevin equation framework, we study
the effect of such a perturbation, in cases of a constant force applied. We
report most of the results arising from our previous analysis and, in the
present work, we show that the Fox $H$-functions formalism provides a compact,
elegant and useful tool for the study of the scaling properties of any
observable. In particular we show how the generalized Kubo fluctuation
relations can be expressed in terms of $H$-functions.
