Query: Perturbation theory in covariant canonical quantization   I investigate a new idea of perturbation theory in covariant canonical
quantization. I present preliminary results for a toy model of a harmonic
oscillator with a quartic perturbation, and show that this method reproduces
the quantized spectrum of standard quantum theory. This result indicates that
when the exact solutions to classical equations are not known, covariant
canonical quantization via perturbation theory could be a viable approximation
scheme for finding observables, and suggests a physically interesting way of
extending the scope of covariant canonical quantization in quantum gravity
