黑色D-$p$-D-$(p+4)$-膜体系在不同系综中的相结构I:热稳定性

Phase structures of the black D$p$-D$(p+4)$-brane system in various ensembles I: thermal stability

Da Zhou, Zhiguang Xiao

摘要:

当带有离域D $p$电荷的D $(p+4)$-膜($p=0,1,2$)与球形热腔处于平衡时,通过在边界上设置不同的条件,这两种电荷可以独立地进入正则系综或巨正则系综.利用热稳定性条件,讨论了该体系的各种系综的相结构,找出了黑膜可能成为系综中最终稳定相的情况。特别地,当D0和D4电荷处于不同种类的系综中时,可以发生范德华类相变。此外,我们的结果还表明D $(p+4)$-膜和离域D $p$-膜是等价的.

英文摘要:

When the D$(p+4)$-brane ($p=0,1,2$) with delocalized D$p$ charges is put into equilibrium with a spherical thermal cavity, the two kinds of charges can be put into canonical or grand canonical ensemble independently by setting different conditions at the boundary. Using the thermal stability condition, we discuss the phase structures of various ensembles of this system formed in this way and find out the situations that the black brane could be the final stable phase in these ensembles. In particular, van der Waals-like phase transitions can happen when D0 and D4 charges are in different kinds of ensembles. Furthermore, our results indicate that the D$(p+4)$-branes and the delocalized D$p$-branes are equipotent.
