One Photon Can Simultaneously Excite Two or More AtomsWe consider two separate atoms interacting with a single-mode optical or microwave resonator. When the frequency of the resonator field is twice the atomic transition frequency, we show that there exists a resonant coupling between one photon ...
The resultant imines (R1HC = N–R2 or R1R2C = N–R3), where R1, R2 and R3 can be any aryl or alkyl groups, can form complexes with metal ions through donation of the lone pair of electrons of nitrogen. One of the most regularly reported NNOO ligands are the salen-type ligands, ...
Compared with the commonly used Ti:sapphire laser (700–1000 nm), this wavelength does not two-photon resonantly excite the soret band of many endogenous fluorophores in cells and tissues and thus, causes the least on-focus damage. Give its advantages for in vivo imaging in deep tissues, it...
we can also excite the bulk state by choosing\(\Delta \omega /{\gamma }_{0}=-10\), where the intensities of the excitation\(| {C}_{n,\pm }(t){| }^{2}\)evolve toward the middle of the atomic array. On the other hand, further increase of disorder...
21 - I shall therefore observe, that as the mind is endow'd with a power of exciting any idea it pleases; whenever it dispatches the spirits into that region of the brain, in which the idea is plac'd; these spirits always excite the idea, when they run precisely into the proper ...
Traditional one-photon absorption (OPA) uses ultraviolet or visible light to excite fluorescent molecules, which can only happen if the photon energy matches the energy difference between the ground state and the excited state [7]. Two-photon absorption (TPA) uses a light source with nearly twice...
Therefore, the incorporation of Ni2+ ions can produce a large amount of Mo vacancies. Mo vacancies favor the separation of the energy-induced electrons and holes, which induce the high catalytic performance in CO2 and H2S conversion, compared to the MoS2/Al2O3 catalyst. Nevertheless, the 6Ni...
