论文摘要
通过激光控制的时间依赖性充电引导的原子气体的库仑爆炸可以通过相同电荷的宏观系统进行建模，该电荷不保守。我们表明，这种系统可以在模仿加速宇宙扩张的空间均匀和各向同性的方式中发展。具体而言，对于恒定的电荷产生速率，由此产生的弗里德曼 - 库仑方程的稳定固定点对应于de安慰剂的类似物。
The Coulomb explosion of an atomic gas steered by laser-controlled time-dependent charging can be modeled by a macroscopic system of identical charges whose number is not conserved. We show that such a system can evolve in the spatially homogeneous and isotropic fashion that mimics accelerating cosmic expansions. Specifically, for a constant rate of charge production, the resulting Friedmann-Coulomb equations have a stable fixed point corresponding to an analog of de Sitter space.
