This concise textual content introduces options from quantum mechanics, specifically scattering idea, to compute the results of an exterior historical past on a quantum box generally, and at the houses of the quantum vacuum specifically. This method may be succesfully utilized in an more and more huge variety of occasions, starting from the research of solitons in box thought and cosmology to the selection of Casimir forces in nano-technology.

The strategy brought and utilized during this ebook is proven to provide an unambiguous connection to perturbation thought, enforcing average renormalization stipulations even for non-perturbative backgrounds. It either supplies new theoretical insights, for instance illuminating longstanding questions relating to Casimir stresses, and likewise presents an effective analytic and numerical instrument well matched to functional calculations. final yet no longer least, it elucidates in a concrete context some of the subtleties of quantum box idea, comparable to divergences, regularization and renormalization, by means of connecting them to extra ordinary ends up in quantum mechanics.

While addressed basically at younger researchers getting into the sphere and nonspecialist researchers with backgrounds in theoretical and mathematical physics, introductory chapters at the theoretical features of the tactic make the publication self-contained and therefore appropriate for complex graduate students.
