Image of FIG. 1.
FIG. 1.

The variation of the order parameter for the final steady phases with shear rate for (a) dimers and (b) tetramers.

FIG. 2.

The variation of the bulk pressure for the final steady phases with shear rate for (a) dimers and (b) tetramers.

FIG. 3.

Dynamic phase diagram showing regions of steady phase as a function of attractive potential depth and shear rate for (a) dimers and (d) tetramers. The symbols represent simulation results showing regions of steady phase. The dish line shows the quiescent ODT and the uncertainty in the determination of ODT. The solid lines mark the critical shear rate where shear-induced ordering occurs. The reduced shift of the critical ordering potential depth with respect to the critical shear rate in (c) dimers and (d) tetramers. The solid line stands for the best power law fit. For dimers, is observed. While for tetramers, is observed.
