Abstract: We investigate N = 4 SYM coupled to fundamental flavours at nonzero imagi-
nary quark chemical potential in the strong coupling and large N limit, using gauge/gravity
duality applied to the D3-D7 system, treating flavours in the probe approximation. The
interplay between ZN symmetry and the imaginary chemical potential yields a series of
first-order Roberge-Weiss transitions. An additional thermal transition separates phases
where quarks are bound/unbound into mesons. This results in a set of Roberge-Weiss
endpoints: we establish that these are triple points, determine the Roberge-Weiss temper-
ature, give the curvature of the phase boundaries and confirm that the theory is analytic
in 2 when 2 0.
