It's driving me nuts. Is the double bond constantly changing between all possibilities fast enough that it shortens the bond length for all, or are all the double bonds existing in all possible states ...

This figure categorized into 2 primary categories: off-chip light source excitation and on-chip light source excitation, distinguished by their approaches to exciting electromagnetic field hotspots.

We consider a two-level quantum system interacting with two classical time-periodic electromagnetic fields. The frequency of one of the fields far exceeds that of the other. The effect of the ...
