👉 In quantum mechanics, a "ronion" is an hypothetical particle that can be described by the following quantum mechanical operator: \[ \hat{O} = -i\hbar\frac{\partial}{\partial x} + e^2x\left[\frac{\partial^{2}}{\partial y^{2}} - \frac{\partial^{3}}{\partial z^{2}} \right] \] This operator describes a particle with spin 1/2, where the spin
