Fermionic particle creation in curved spacetime: Physical Bloch-vector dynamics and exact de Sitter scaling

We formulate fermionic particle creation in a time-dependent curved spacetime as the exact evolution of a physical Bloch vector. Each Dirac momentum mode reduces to a two-level system, and its instantaneous occupation is obtained by projecting the physical state onto the instantaneous energy basis. This construction is...
