Renormalization Group Transformation for the Wave Function

High Energy Physics - Theory 2009-10-30 v2 Mesoscale and Nanoscale Physics Quantum Physics

Abstract

The problem considered here is the determination of the hamiltonian of a first quantized nonrelativistic particle by the help of some measurements of the location with a finite resolution. The resulting hamiltonian depends on the resolution of the measuring device. This dependence is reproduced by the help of a blocking transformation on the wave function. The systems with quadratic hamiltonian are studied in details. The representation of the renormalization group in the space of observables is identified.
