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…

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-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…
