In particular, we investigate the effects of changing the number of atoms, the intracavity lattice depth, and the atom-light coupling strength, and show how resonances between the Bloch oscillation dynamics and the quasiparticle spectrum have a strong influence on the signal-to-noise ratio, as ...
对照凝聚态系统中的Bloch oscillation,进行简单说明:算了,不说了。知乎的编辑系统好烦人。Bloch振荡大家都懂的哦。 对于非相对论性的低速电子(例如100eV),电子的色散无法忽略。因此当同步条件 \omega_L - v_0 q = 0 满足时,失谐项主要由电子的色散项提供,方程(9)可以改写为 i \frac{∂}{∂t} a_n...

So, in October 1927 before the beginning of the winter semester, I left my nice home town for the first time, to arrive on a cold gray morning in that rather ugly city of Leipzig. The little room I found for rent from a family overlooked a railroad yard; the noise and smoke did not...
