Although it is possible that new attempts to estimate the vacuum energy density may yield just the right amount to explain cosmic acceleration, many theorists believe that a correct calculation, incorporating a new symmetry principle, will lead to the conclusion that the energy associated with the quantum vacuum is zero.
虽然新的估算有可能得到能解释加速膨胀现象的真空能量密度,但多数科学家相信,经过正确的计算再配上新的对称性原理,得到的量子真空能量将会是零。

It is found that amplitude-squared squeezing can be created by 4-photon unitary operator S4 acting on the vacuum state and this shows that the amplitude-squared squeezing can be created by 4-photon unitary operator S4 acting on the vacuum state and this shows that the amplitude-squared squeezing is a new nonclassical effect of light field which is independent of the second order squeezing, antibunching and sub-poisson statistics.
发现4个光子么正算符S4对真空态的作用可以产生振幅平方压缩,这表明振幅平方压缩是一种独立于二阶压缩、反聚束以及亚泊松统计分布的新的光场非经典效应。标签 K光子么正算符相干态真空态振幅平方压缩 K-photon unitary operator coherent state vacuum state amplitudesquared squeezing

From our result, we can see that unphysical components of the gauge fields are contributive to the vacuum energy and it just cancel out ghost fields contribution to the vacuum energy.
从计算结果来看,规范场的物理分量和非物理分量对真空的零点能都有贡献,而规范场的非物理分量对真空能量的贡献,不仅不包含M-C-S规范场的质量项,而且恰好与鬼场的贡献相抵消。
