A rigorous Hermitian proof about the G-dynamics and analogy with Berry-Keating's Hamiltonian

Abstract

Quantum covariant Hamiltonian system theory provides a coherent framework for modelling the complex dynamics of quantum systems. In this paper, we centrally deal with the Hermiticity of quantum operators that directly links to the physical observable, thusly, we give a rigorous proof to verify one-dimensional G-dynamics ${{\hat{w}}^{\left( cl \right)}}={{\hat{w}}^{\left( cl \right)\dagger }}\in Her$ that is a Hermitian operator satisfying $\left( {{{\hat{w}}}^{\left( cl \right)}}\phi ,\varphi \right)=\left( \phi ,{{{\hat{w}}}^{\left( cl \right)}}\varphi \right)$ for any two states $\phi$ and $\varphi$, and its eigenvalues are real. We also prove that curvature operator is a skew-Hermitian operator as well. The act of finishing this Hermitian proof valuably enables us to ensure the non-Hermitian Hamiltonian operator ${{\hat{H}}^{\left( ri \right)}} ={{\hat{H}}^{\left( g \right)}} -{{\hat{H}}^{\left( \operatorname{clm} \right)}}\in NHer$ that is divided into the Hermitian operator ${{\hat{H}}^{\left( g \right)}} ={{\hat{H}}^{\left( cl \right)}}-{{E}^{\left( s \right)}}/2\in Her$ and the skew-Hermitian operator ${{\hat{H}}^{\left( \operatorname{clm} \right)}}=\sqrt{-1}\hbar {{\hat{w}}^{\left( cl \right)}}\in SHer$ generally, and ${{\hat{H}}^{\left( ri \right)}}$ always has the complex eigenvalues. We use the formula of the G-dynamics to evaluate the Berry-Keating's Hamiltonian operator ${{\hat{H}}^{\left( \text{bk}\right)}}=-\sqrt{-1}\hbar \hat{\theta }/2\in Her$ and its extensive version $\hat{H}^{\left( \text{gbk}\right)}\in NHer$ as the applications of the G-dynamics, to see how the similarity appears in the light of obvious factor $\hat{\theta }/2=x\frac{d}{dx}+1/2\in SHer$, etc.
