Melting of devil's staircases in the long-range Dicke-Ising model
Jan Alexander Koziol, Anja Langheld, Kai Phillip Schmidt
We present quantum phase diagrams for the antiferromagnetic long-range Ising model with a linear coupling to a single bosonic mode on the square and triangular lattice. For zero co…
Quantum phase diagrams of Dicke-Ising models by a wormhole algorithm
Anja Langheld, Max Hörmann, Kai Phillip Schmidt
We gain quantitative insights on effects of light-matter interactions on correlated quantum matter by quantum Monte Carlo simulations. We introduce a wormhole algorithm for the par…
Quantum-critical properties of the one- and two-dimensional random transverse-field Ising model from large-scale quantum Monte Carlo simulations
C. Krämer, J. A. Koziol, A. Langheld +2
We study the ferromagnetic transverse-field Ising model with quenched disorder at in one and two dimensions by means of stochastic series expansion quantum Monte Carlo simu…
Monte Carlo based techniques for quantum magnets with long-range interactions
P. Adelhardt, J. A. Koziol, A. Langheld +1
Long-range interactions are relevant for a large variety of quantum systems in quantum optics and condensed matter physics. In particular, the control of quantum-optical platforms…
