Modulating the phase structure of black D6 branes in canonical ensemble    [PDF]

J. X. Lu, Ran Wei

In [1], we find that the phase structure of charged black D5 system can be changed qualitatively by adding the delocalized D1 branes but the similar change resists to happen for the charged black D6 system through adding the delocalized D2 branes, giving rise to the same type of D(p - 4)/Dp. Adding the delocalized D4 branes to the black D6 branes doesn't work, either. In this paper, we consider further to add the delocalized D0 branes, the only remaining lower dimensional branes, to the black D6 system for this purpose. We find that the delocalized charged black D0-branes alone share the same phase structure as the charged black D6 branes, having no van der Waals-Maxwell liquid-gas type. However, when the two are combined to form D0/D6, the resulting phase diagram has finally been changed dramatically to the wanted one, containing now the above liquid-gas type. This change arises from the interaction between the delocalized D0 and D6.
