[100% PhD in Math + 50% major in Physics here]<p>Is this published in a serious journal?<p>It looks like a lot of technical jargon that doesn't make any sense. The quantization of the harmonic oscillator is important only for very small systems. The swing in the park is quantized, but the difference with a classical oscillator is negligible. Then financial market may be quantized, but the effect is ultra tiny. And to notice the quantum effects the system must be almost isolated, so there is no chance to see something like that in the financial market.<p>Perhaps there is a chance that the it's only a model that fit the data in spite there is absolutely no theoretical reason. It's possible, but it's much easier to overfit the model with the historic data. Do they have any prediction?<p>Relevant xkcd: <a href="https://xkcd.com/1240/" rel="nofollow">https://xkcd.com/1240/</a>
