我们用大D有效理论作为全息冲击波碰撞的模型,研究了高斯质量密度斑点在全息等离子体中的碰撞。有效理论的简单性使我们可以在爱因斯坦-麦克斯韦理论中实现最初的4+1碰撞,这与具有非零重子数的物质的碰撞是对偶的。我们研究了几种具有不同斑点形状、碰撞参数和电荷值的碰撞场景,发现碰撞参数在斑点横向宽度以下的碰撞在重新标度下是等价的。我们还观察到电荷对其余量的影响很小。最后,我们研究了碰撞过程中由电荷扩散和粘性耗散产生的熵。确定了线性熵增长的多个阶段,其速率不独立于初始条件。
We study collisions of Gaussian mass-density blobs in a holographic plasma, using a large D effective theory, as a model for holographic shockwave collisions. The simplicity of the effective theory allows us to perform the first 4+ 1 collisions in Einstein-Maxwell theory, which are dual to collisions of matter with non-zero baryonic number. We explore several collision scenarios with different blob shapes, impact parameters and charge values and find that collisions with impact parameter below the transverse width of the blobs are equivalent under rescaling. We also observe that charge weakly affects the rest of quantities. Finally, we study the entropy generated during collisions, both by charge diffusion and viscous dissipation. Multiple stages of linear entropy growth are identified, whose rates are not independent of the initial conditions.
