Renormalization for harmonic oscillators
Hidenori Sonoda
Kobe University, Japan
I introduce a class of free theories of harmonic oscillators that require renormalization. The theories describe a harmonic oscillator coupled with a continuous spectrum of oscillators. In particular I will explain two models: the first mimics the mass renormalization of the three dimensional scalar theory, and the second mimics the renormalization of a mass, coupling, and wave function of the four dimensional scalar theory.
