Geometric interpretation of the hyperfine Breit--Rabi solution
Lihong V. Wang
We present a geometric interpretation of the hyperfine Breit--Rabi eigenvalues and eigenvectors in alkali atoms after reformulating the standard solution into a compact form. In th…

Deriving the von Neumann equation from the Majorana-Bloch equation for arbitrary spin in any state
Lihong V. Wang
After publishing the derivation from the classical Bloch equation to the quantum von Neumann equation to the Schrdinger-Pauli equation for spin-, we proposed renaming…

Derivations of Bloch (Majorana--Bloch) equation, von Neumann equation, and Schrödinger--Pauli equation
Lihong V. Wang
The transition from classical physics to quantum mechanics has been mysterious. Here, we derive the space-independent von Neumann equation for electron spin mathematically from the…
