暗能量是宇宙卡西米尔效应吗?

Is Dark Energy a Cosmic Casimir Effect?

Kevin Cahill

摘要:

未知的短距离效应抵消了零点能量的四次发散。如果这种重整化在最后一次相变后的早期宇宙中生效,并且只适用于波长(超过2 π)短于当时哈勃长度1/H的模,那么波长较长的模的零点能量可以近似地解释暗能量密度的当前值。该模型做出了两个预测。

英文摘要:

Unknown short-distance effects cancel the quartic divergence of the zero-point energies. If this renormalization took effect in the early universe after the last phase transition and applied only to modes whose wavelengths (over 2 pi) were shorter than the Hubble length 1/H at that time, then the zero-point energies of the modes of longer wavelengths can approximately account for the present value of the dark-energy density. The model makes two predictions.
