The classical Hochschild-Kostant-Rosenberg theorem identifies Hochschild homology of smooth algebras with the de Rham complex. In this talk, I want to explain a generalisation of this to topological Hochschild homology of nondiscrete ring spectra, where the role of the de Rham complex is taken by an "eta-deformed de Rham complex" which involves interesting homotopical information.
