Folds of one curve: the superradiant phase diagram of Dicke modes with interacting matter
Max Hörmann
We give a thermodynamic-limit account of Dicke models with one cavity mode coupled collectively to interacting matter. Integrating out the cavity yields an exact self-consistent fu…

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…

Comment on "Role of Matter Interactions in Superradiant Phenomena"
Max Hörmann, Anja Langheld, Jonas Leibig +2
Recently, Mendonça et al. [arXiv:2503.04961] investigated the Dicke-XXZ model and the Dicke-Ising model. For the latter model, their calculated quantum phase diagram contradicts c…
