Thermodynamic-limit dispersion relations on trapped-ion quantum hardware
Lucas Marti, Sumeet, Stefan Wolf +2
We run a numerical linked-cluster expansion with a quantum algorithm (NLCE+QA), computing ground-state energies and one quasi-particle dispersions in the thermodynamic limit using…

Quantitative approach for the Dicke-Ising chain with an effective self-consistent matter Hamiltonian
J. Leibig, M. Hörmann, A. Langheld +2
In the thermodynamic limit, the Dicke-Ising chain maps exactly onto an effective self-consistent matter Hamiltonian with the photon field acting solely as a self-consistent effecti…
