An Alternative Canonical Approach to the Ghost Problem in a Complexified Extension of the Pais-Uhlenbeck Oscillator
A. Déctor, H. A. Morales-Técotl, L. F. Urrutia +1
Our purpose in this paper is to analyze the Pais-Uhlenbeck (PU) oscillator using complex canonical transformations. We show that starting from a Lagrangian approach we obtain a tra…

Coping with the Pais-Uhlenbeck oscillator's ghosts in a canonical approach
Aldo Déctor, Hugo A. Morales-Técotl, Luis F. Urrutia +1
A {\em complex} canonical transformation is found that takes the fourth order derivative Pais-Uhlenbeck oscillator into two independent harmonic oscillators thus showing that this…
