Derivations of Bloch (Majorana–Bloch) equation, von Neumann equation, and Schrödinger–Pauli equation

Kavli Affiliate: Lihong V. Wang | First 5 Authors: Lihong V. Wang, , , , | Summary: 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 classical Bloch or Majorana–Bloch equation, which is also derived. Subsequently, the space-independent Schr"odinger–Pauli […]
