Quantization based on generalized Poisson brackets

Ray LaPierre

Yavuz Nutku

Nambu's construction of multi-linear brackets for super-integrable systems can be thought of as degenerate Poisson brackets with a maximal set of Casimirs in their kernel. By introducing privileged coordinates in phase space these degenerate Poisson brackets are brought to the form of Heisenberg's equations. We propose a definition for constructing quantum operators for classical functions, which enables us to turn the maximally degenerate Poisson brackets into operators. They pose a set of eigenvalue problems for a new state vector. The requirement of the single-valuedness of this eigenfunction leads to quantization. The example of the harmonic oscillator is used to illustrate this general procedure for quantizing a class of maximally super-integrable systems.

We discuss a manifestly covariant way of arriving at the quantization rules based on the causality, with no reference to Poisson or Peierls brackets of any kind.K e y w o r d s: quantization rules, Poisson brackets, Peierls brackets.
