Within the context of the duality between higher spin gravitational theories and a semi- classical limit of W_N minimal models, we consider 2D CFTs with W_∞ symmetry at finite temperature, deformed by the presence of a chemical potential for the spin–three current. As a perturbative expansion in the chemical potential, we compute the Renyi and entanglement entropies for a single interval. The leading correction is universal and matches the holographic result, based on Wilson line functionals, obtained from the higher spin gravitational dual.
