唤醒相对论恒星中的真空

Awaking the vacuum in relativistic stars

William C. C. Lima, George E. A. Matsas, Daniel A. T. Vanzella

摘要:

真空中没有经典物理学中的任何固有结构,但在相对论量子物理学中,各种各样的过程令人难以置信地拥挤。然而,它的直接影响通常是如此微妙,以至于它的结构几乎和经典物理学一样难以捉摸。在这里,相比之下,我们报告发现了一种新的效果,根据这种效果,真空被迫在天体物理学背景下发挥意想不到的核心作用。我们证明了相对论性恒星的形成可能导致量子场的真空能量密度呈指数增长。随后的真空驱动演化可能会给天体物理学带来意想不到的影响,而对稳定的中子星构型的观测可能会让我们了解宇宙的场内容。

英文摘要:

Void of any inherent structure in classical physics, the vacuum has revealed to be incredibly crowded with all sorts of processes in relativistic quantum physics. Yet, its direct effects are usually so subtle that its structure remains almost as evasive as in classical physics. Here, in contrast, we report on the discovery of a novel effect according to which the vacuum is compelled to play an unexpected central role in an astrophysical context. We show that the formation of relativistic stars may lead the vacuum energy density of a quantum field to an exponential growth. The vacuum-driven evolution which would then follow may lead to unexpected implications for astrophysics, while the observation of stable neutron-star configurations may teach us much on the field content of our Universe.
