Analytical Lindblad Dynamics of Field-Controlled Entanglement and State Fidelity in the Hydrogen Electron-Proton Spins: Interplay of Hyperfine Coupling, Zeeman Effects, and Pure Dephasing

In this paper, we investigate the dynamics of quantum correlations in the ground-state hyperfine manifold of the hydrogen atom subjected to a static external magnetic field and local pure dephasing. The electron–proton spin pair is modeled as a bipartite two-qubit system evolving under the combined...
