A relation between the motivic Donaldson-Thomas invariants of Kontsevich and Soibelman and the cohomology of character varieties will be shown to arise naturally in stringtheory. This yields in particular a string theoretic derivation of a conjecture of Hausel, Letellier and Rodriguez-Villegas and generalizations. This is based on work with Wu-yen Chuang, Ron Donagi and Tony Pantev.
