Renormalization group transformation for the wave function
DOI:10.1006/aphy.1998.5827.png)
摘要
En 中文
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 with the help of a blocking transformation on the wave function. The systems with quadratic hamiltonian are studied in detail. The representation of the renormalization group in thr space of observables is identified. (C) 1998 Academic Press.
