论文摘要
在旋转波框架中产生的有效共轭对称性是场理论中离散对称性的类似物。打破这种有效的共轭对称性会导致量子光学系统中上和下降激发之间的不对称性。我们使用半经典量子光学学理论来描述这些过程，并通过实验表征原子蒸气细胞中的两色饱和吸收光谱（SAS）的光学响应中的不对称性。这样做证明了与最简单的瘦生成模型的理论和现象学对应关系，据称我们的宇宙从同等数量的物质和反气管变成了目前的物质过剩的过程。由于chirp下的离散对称性破裂而对不对称性的理解似乎阐明了导致文献中先前指出的其他Chirp不对称的基本过程。
The effective conjugation symmetry that arises in the rotating wave frame is the analogue of the discrete symmetry in field theory. Breaking this effective conjugation symmetry leads to asymmetries between up- and down- chirped excitation in quantum optical systems. We use semiclassical quantum optics theory to describe these processes and experimentally characterize the asymmetry in the optical response in chirped, two-color saturated absorption spectroscopy (SAS) in an atomic vapor cell. Doing so demonstrates a theoretical and phenomenological correspondence to the simplest model of leptogenesis, the process by which our universe purportedly went from equal amounts of matter and antimater to its present matter excess. The understanding of the asymmetry as due to a broken discrete symmetry under chirp appears to illuminate the underlying processes responsible for other chirp asymmetries previously noted in the literature.
