Avoiding Ultraviolet Divergence by Means of Interior–Boundary
... Suppose that x-particles can emit and absorb y-particles, and consider a single x-particle fixed at the origin. For simplicity, we take the x- and y-particles to be spinless, and we intend to cut off from the Fock space for the y-particles any sector with particle number 2 or higher. To this end, we ...

... it, and of how quantum mechanics is to be applied. With this we know what physics is about, and how it is to go on. Now for the measurement problem on this strategy. A first version is this: microscopic systems (and hence the macroscopic) are in some sense probabilistic. If the state says all there ...

Effective nuclear charge is the apparent nuclear charge exerted on a particular electron, equal to the actual nuclear charge minus the effect of electron repulsions. We often focus on the effective nuclear charge felt by the outermost electron which is ...
