Dressed coordinates: the path-integrals approach
arXiv:physics/0506223 · doi:10.1016/j.physa.2006.08.039
Abstract
The recent introduced \textit{dressed coordinates} are studied in the path-integral approach. These coordinates are defined in the context of a harmonic oscillator linearly coupled to massless scalar field and, it is shown that in this model the dressed coordinates appear as a coordinate transformation preserving the path-integral functional measure. The analysis also generalizes the \textit{sum rules} established in a previous work.
