Quantum interactions

Instantaneous action at a distance, represented here by longitudinal components, can thus be interpreted as a classical equivalent of nonlocal quantum interactions [2]. 

In order to avoid awkward explanation of the precise nature of this, so-called dispersion interaction, many authors label it a quantum interaction without classical analogue, content that it should remain a mystery. The similarity between van der Waals, metallic and ionic interactions in the solid state, argues against this dictum. 

The preceding discussions show that the amplitude at the midpoint between the slits but calculated now at the detector screen xD can be modulated in different manners this modulation should be reflected at the screen where we may place an energy conserving detector device. The quantum interactions at the two slits determine the type of response to be measured at the recording screen. The fringes may disappear if the amplitudes Q and C2 are independently changed thereby breaking coherence. 

Quantum and classic theoretic frameworks relies on coordinate sets, and the origin of which is defined with respect to space-time inertial frame characteristic of special relativity framework. A clear-cut correspondence is never a transparent endeavor the origin of an I-frame designates a junction point. Care is required to differentiate real space from configuration space situations. Yet quantum interactions between inner and outer states couple both levels as mentioned earlier, for example, EPR entanglement cases. 

Another type of echo that is receiving much attention are fifth-order echoes, which are also based on Raman interactions (56-60). The majority of studies have looked at intermolecular interactions (11,43-54), but a few studies have looked at an intramolecular vibrational overtone (47,48). Compared to the Raman echo, the fifth-order echo replaces a pair of interactions by a single, double-quantum interaction. Although the fifth-order experiments are formally of lower order than the Raman echo, the doublequantum interaction is forbidden in the harmonic approximation. As a result, it is not clear that the signal from a fifth-order echo will be stronger than that from a seventh-order Raman echo. 

In an analogous manner we assume for the quantum interaction between radiation and atomic systems the three corresponding processes. Between the two energy levels W x and W2 there are then the following transitions ... 

At first sight this looks like an unanswerable objection to the vibrational theory, and it is indeed unanswerable if it be held that the possession of one or two musk-favorable and no musk-adverse frequencies is a necessary and sufficient condition for the specific odorous sensation to be perceived. But it has already been shown elsewhere that the probability of a quantum interaction and the stimulatory efficiency of a moleucle depend upon such additional factors as the frequency of the lowest vibrational mode which correlates with the threshold concentration (15). or the flexibility of the molecule which is related to the way the intensity of the sensation varies with the concentration of the stimulus (16). Also, it has been suggested that we...
