Cyber-Physical Systems (IoT and OT),ical bistability, etc. Alternatively one can use them to study the properties of the medium that generates them. The various kinds of nonlinear spectroscopy fall into the second category. Saturation spectroscopy deals typically with the . absorption of waves passing through a medium to be studied.

When computing the atomic decay rate, we were not interested in the field itself, but only on its effect on the atomic dynamics. Thus we never explicitly computed娘娘腔 发表于 2025-3-31 15:31:36

For example, the position and momentum standard deviations obey the uncertainty relation . and we can squeeze . to an arbitrarily small value at the expense ofascend 发表于 2025-4-1 00:46:55
