Finite quantum model captures nonlinear classical wave dynamics

This paper shows that quantizing and discretizing the classical three-wave interaction equations results in a finite-dimensional quantum system that can approximate solutions to the original nonlinear classical system. By tuning parameters like dimensionality and initial variance, the correspondence between the quantum and classical systems can be extended over longer time periods. The quantum system is able to capture qualitative dynamics like periodicity as well as quantitative measures like frequency, despite being linear. This demonstrates the utility of field-theoretic quantization for modeling finite-dimensional quantum analogues of nonlinear classical systems.
