Dicke-Ising Chain Analysis Achieves Improved Accuracy in Magnetically Ordered Phases with NLCE+DMRG

Researchers combined numerical linked‑cluster expansions (NLCE) with density‑matrix renormalization‑group (DMRG) to map the Dicke‑Ising chain onto a self‑consistent effective matter Hamiltonian, eliminating photon‑spin correlation calculations. This hybrid method achieved phase‑diagram precision of 10⁻⁴ for ferromagnetic couplings and confirmed a narrow antiferromagnetic superradiant phase. The work links the Dicke‑Ising model to a transverse‑field Ising model with a longitudinal field, clarifying the nature of its quantum phase transitions. The findings provide a robust computational framework for future quantum‑light‑matter studies.
