The Widom-Rowlinson model ^[1] for mixtures takes the form:

\Phi \left(r_{ij}\right)=0

; if

i

and

j

are particles of the same species

\Phi \left(r_{ij}\right)=\Phi _{HS}(r_{ij});

if

i

and

j

belong to different species,

The surface tension of the Widom-Rowlinson model has been studied by:
