论文摘要
我们构建了与反向反应的D0/D4-Brane系统相对应的超级实力背景。背景在Berkoos-Douglas矩阵模型的Venecianno极限上是双重双重的。众所周知，当D0-branes在D4-branes内时，局部D0/D4系统是不稳定的。为了避免这一困难，我们将D4S与D0S分开，该D0S放置在原点，并通过在D0-Branes周围的球形壳上分配D4-branes来恢复组合系统的对称性。首先在N_F/N_C中扰动地获得反应的解决方案，并分析显示为一阶。然后提出非扰动数值解决方案。
We construct a supergravity background corresponding to a backreacted D0/D4-brane system. The background is holographically dual to the Venecianno limit of the Berkoos-Douglas matrix model. It is known that the localized D0/D4 system is unstable when the D0-branes are within the D4-branes. To circumvent this difficulty we separate the D4s from the D0s, which are placed at the origin, and restore the symmetry of the combined system by distributing the D4-branes on a spherical shell around the D0-branes. The backreacted solution is first obtained perturbatively in N_f/N_c and displayed analytically to 1st order. A non-perturbative numerical solution is then presented.
