We present results from an extensive simulational study of the modulated liquid $\longleftrightarrow$ crystal transition in a 2-d charge-stabilized colloid subject to a 1-d laser field modulation commensurate with the crystalline phase. {\em {Contrary to some earlier simulational and experimental findings we do not find any reentrant liquid phase in our simulation. Furthermore the transition remains first-order (albeit weak, with a fairly large correlation length) even in the limit of infinite…

It is shown that the system does indeed display a LIF transition, although the interaction potential is markedly different from the cases studied before, and a theoretical description of the onset of LIF is suggested which is based on the pressure-balance equation relating the pressure tensor and the external potential.
