Quantum phase transition in the quantum compass model Han-Dong Chen
... However, due to the special structure of both the spin interactions and the lattice, we show that the gauge interaction for the compass model is absent, which allows us to apply conventional approximation techniques developed for electron systems to analyze the original spin model. Our approximation ...

EXAM 3 - University of Utah Physics
... A massless spring is attached at one end to the lower end of a rough track. The track sits at an angle θ with respect to the earth’s surface. A small mass m is placed on the track and is pushed against the spring, but is not attached to the spring. This results in a compression of the spring from it ...

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.
