量子物理学家在奇异实验中发现“负时间”Quantum Physicists Discover 'Negative Time' in Strange Experiment
➀ 量子物理学家观察到，光子在原子的激发态中可以花费负时间，似乎在进入材料之前就离开了它；➁ 这一现象最初于2017年提出，现在已被实验证实；➂ 研究人员使用冷原子云进行实验，发现有时光子穿过原子云而不激发原子，但原子仍然变得激发；➃ 结果表明，当光子激发原子时，光子在介质中的传播速度比原子处于基态时更快。➀ Quantum physicists have observed that photons can spend a negative amount of time in the excited state of atoms, seemingly exiting a material before entering it; ➁ The phenomenon was first proposed in 2017 and has now been experimentally confirmed; ➂ The researchers used a cloud of chilled atoms and found that sometimes photons pass through without exciting the atoms, yet the atoms still become excited; ➃ The results suggest that the photons moved through the medium faster when they excited the atoms than when the atoms remained in their ground state.
