Field Formulation of Many-Body Quantum Physics {ffmbqp
... As a first step towards developing this powerful theory we shall start from the well-founded Schrödinger theory of nonrelativistic spinless particles. We show that there exists a completely equivalent formulation of this theory in terms of quantum fields. This formulation will serve as a basis for ...

Are Quantum States Exponentially Long Vectors?
... does BQP/qpoly = BQP/poly, where BQP/poly is the class of problems solvable in quantum polynomial time with the aid of polynomial-size classical advice? As usual in complexity theory, the answer is that we don’t know. This raises a disturbing possibility: could quantum advice be similar in power to ...

Superstring Theory and Empirical Testability - Philsci
... 2. Empirical testability: The propositions of a theory have to be empirically testable under consideration of the scientific concepts and structures, used by the theory, and of the relevant rules of interpretation. Theories have to face the tribunal of empirical data. If they don't, they are no more ...

Renormalization
In quantum field theory, the statistical mechanics of fields, and the theory of self-similar geometric structures, renormalization is any of a collection of techniques used to treat infinities arising in calculated quantities.Renormalization specifies relationships between parameters in the theory when the parameters describing large distance scales differ from the parameters describing small distances. Physically, the pileup of contributions from an infinity of scales involved in a problem may then result in infinities. When describing space and time as a continuum, certain statistical and quantum mechanical constructions are ill defined. To define them, this continuum limit, the removal of the ""construction scaffolding"" of lattices at various scales, has to be taken carefully, as detailed below.Renormalization was first developed in quantum electrodynamics (QED) to make sense of infinite integrals in perturbation theory. Initially viewed as a suspect provisional procedure even by some of its originators, renormalization eventually was embraced as an important and self-consistent actual mechanism of scale physics in several fields of physics and mathematics. Today, the point of view has shifted: on the basis of the breakthrough renormalization group insights of Kenneth Wilson, the focus is on variation of physical quantities across contiguous scales, while distant scales are related to each other through ""effective"" descriptions. All scales are linked in a broadly systematic way, and the actual physics pertinent to each is extracted with the suitable specific computational techniques appropriate for each.
