Variational non-gaussian approach to interacting spin-boson models
João Pedro Mendonça, Yao Wang, Krzysztof Jachymski
We apply a hybrid variational framework to interacting spin-boson Hamiltonians, targeting regimes where simulations are limited by the unbounded bosonic Hilbert space and strong ma…

Role of Matter Interactions in Superradiant Phenomena
João Pedro Mendonça, Krzysztof Jachymski, Yao Wang
The superradiant phenomenon, usually described by the Dicke model, is a hallmark of strong light-matter interaction. We explore how matter-matter interactions influence this phenom…
