    • Throughout this paper we call feedback the reaction of the field structure, coming from the superposition of the counter-propagating pump and probe, on the atomic variables: position and momentum. This reaction closes the loop which sees the atoms modify the field configuration (relative amplitude and phase) and the field act back onto the atoms modifying their positions and speeds.

    • We remark and the approximation adopted in Ref. [53], where the averages of the products containing the atomic momentum and its polarization are done separately - as is commonly done also for the field-polarization terms -, is certainly not a cause of concern for the regime of parameters which we explore in this paper. Indeed, we are intrested in investigating the situation where collisions occur fairly infrequently and where the time scales over which momentum and polarization are very different (cf. later in this section, in particular, Fig. 1). Thus, we can consider the momentum constant over the typical response time of the atomic polarization and factor the averages.

    • We have tested the effect of collisions between bodies of different masses (i.e., collisions where imperfect transfer of energy and momentum takes place). Preliminary numerical runs show that, aside from quantitative modifications, the physics of the observed phenomena (the phase transition) remains unaltered.

    • This statement is basically equivalent to assuming that no density grating is to be expected. While this holds true in the parameter region investigated in this paper, we do not rule out the possibility that such a grating may rise for sufficiently large pump intensities or at sufficiently low temperatures.
