We set the interaction between B patches to zero and calculate the phase diagram as the ratio between the AB and the AA interactions, {\\epsilon}^\\star_AB, varies. In line with previous work, on three-dimensional off-lattice models, we show that the liquid-vapor phase diagram exhibits a re-entrant or \"pinched\" shape for the same range of \\epsilon^\\star_AB, suggesting that the ratio of ","authors_text":"J.
