# Time quantization and q-deformations

@article{Albanese2003TimeQA, title={Time quantization and q-deformations}, author={Claudio Albanese and Stephan Lawi}, journal={Journal of Physics A}, year={2003}, volume={37}, pages={2983-2987} }

We extend to quantum mechanics the technique of stochastic subordination, by means of which one can express any semi-martingale as a time-changed Brownian motion. As examples, we considered two versions of the q-deformed harmonic oscillator in both ordinary and imaginary time and show how these various cases can be understood as different patterns of time quantization rules.
