Imaging of single-chromophore molecules in aqueous
... There are already many excellent accounts of single molecule imaging in the literature. However, most of these differ from what we are trying to achieve in that the molecules are immobilized or have restricted motion. Betzig, et al. first reported near-field imaging of individual molecules on a soli ...

An Overview of High Speed Semiconductor Lasers
... Absorption is proportional to the probability that we find electron and hole at the same “position” (i.e. r=0). For central force problem, we only need to evaluate the envelope wavefunction for the relative motion and take the square of its absolute value. Note the factor of 2 in the formula of the ...
