Fermionic Particle Creation in Curved Spacetime: Physical Bloch-Vector Dynamics and Exact de Sitter Scaling
Samak Boonpan
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 sys…

Quantum Circuit Complexity as a Measure of Particle Creation in Bouncing Cosmologies
Samak Boonpan
We investigate the evolution of circuit complexity for a quantum scalar field in a non-singular bouncing cosmological background. Unlike previous perturbative approaches, we utiliz…
