We consider the large-scale behaviour of the local entropy and the spatially bipartite entanglement entropy of thermal equilibrium states of non-interacting fermions in position space $\mathbb R^d$ ($d\ge 1$) at temperature, $T\ge0$. This leads to the study of the asymptotics of traces of non-smooth functions of Wiener--Hopf operators with smooth (at $T>0$) symbols and discontinuous symbols (at $T=0$). This is joint work work with Hajo Leschke and Alexander V. Sobolev.
