On the Solution of the Tavis-Cummings Hamiltonian in Quantum Optics: Structure and Dynamics Based on the Collective Spin Basis

We present a comprehensive theoretical and computational study of the Tavis–Cummings model in the collective-spin basis, addressing both its static spectral properties and dynamic behavior under unitary and open-system evolution. By exploiting the commutation of the total-excitation operator with th...
