Canonical quantization of the Pais-Uhlenbeck oscillator with a higher-derivative perturbation: a covariant phase space approach
Jie-qiang Wu, Jinan Zhao
In this paper, we apply the covariant phase space formalism to the perturbative canonical quantization of the Pais-Uhlenbeck oscillator, with the acceleration-squared term treated…

Canonical quantization for effective theories with perturbations altering degrees of freedom: a covariant phase space approach
Jie-qiang Wu, Jinan Zhao
The standard approach to canonical quantization encounters difficulties in dealing with perturbations that alter the kinetic structure of unperturbed theories. We show that the cov…
