论文摘要
我们表明，在通货膨胀期间，在非束戴戴维的真空中释放的超耐跑式模式的能量密度可能是任意的，并且在随后以ERA为主导的辐射中降低了LN（A）/A^4。这可能构成一个黑暗的辐射成分，可以充分改变早期的宇宙学演变以减轻哈勃张力。
We show that the energy density of the superhorizon modes released in a non-Bunch-Davies vacuum can be arbitrarily large during inflation and it decreases like ln(a)/a^4 in the subsequent radiation dominated era. This may constitute a dark radiation component which can sufficiently alter the early cosmological evolution to alleviate the Hubble tension.
