碰撞电磁波中出现的宇宙学常数
Emergent cosmological constant from colliding electromagnetic waves
摘要：
在这项研究中，我们主张的观点，宇宙学常数是电磁（em）的起源，它可以产生的碰撞电磁冲击波耦合引力冲击波。参与碰撞的波形具有不同的振幅。结果表明，等振幅波的圆偏振不产生宇宙学常数。我们还证明了宇宙学常数的产生与线偏振有关。交叉极化的增加不会产生宇宙学常数。根据波振幅的大小，产生的宇宙学常数可以是正的，也可以是负的。我们还证明了在一类特殊的Born-Infeld理论中，非线性电磁波的碰撞也产生一个宇宙学常数.
英文摘要：
In this study we advocate the view that the cosmological constant is of electromagnetic (em) origin, which can be generated from the collision of em shock waves coupled with gravitational shock waves. The wave profiles that participate in the collision have different amplitudes. It is shown that, circular polarization with equal amplitude waves does not generate cosmological constant. We also prove that the generation of the cosmological constant is related to the linear polarization. The addition of cross polarization generates no cosmological constant. Depending on the value of the wave amplitudes, the generated cosmological constant can be positive or negative. We show additionally that, the collision of nonlinear em waves in a particular class of Born-Infeld theory also yields a cosmological constant.
