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…

Quantum Monte Carlo study of the bond- and site-diluted transverse-field Ising model
C. Krämer, C. Krämer, M. Hörmann +2
We study the transverse-field Ising model on a square lattice with bond- and site-dilution at zero temperature by stochastic series expansion quantum Monte Carlo simulations. Tunin…

Hybrid quantum-classical algorithm for the transverse-field Ising model in the thermodynamic limit
Sumeet, M. Hörmann, K. P. Schmidt
We describe a hybrid quantum-classical approach to treat quantum many-body systems in the thermodynamic limit. This is done by combining numerical linked-cluster expansions (NLCE)…
