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…

Dynamic structure factor of Heisenberg bilayer dimer phases in the presence of quenched disorder and frustration
M. Hörmann, K. P. Schmidt
We investigate the influence of quenched disorder on the dynamic structure factor of Heisenberg bilayers on the square, triangular, and kagome lattice in the quantum paramagnetic p…

The Ising model in a light-induced quantized transverse field
J. Rohn, M. Hörmann, Claudiu Genes +1
We investigate the influence of light-matter interactions on correlated quantum matter by studying the paradigmatic Ising model subject to a quantum Rabi coupling. This type of cou…
