Transformer Wave Function for Quantum Long-Range models
Sebastián Roca-Jerat, Manuel Gallego, Fernando Luis +2
We employ a neural-network architecture based on the Vision Transformer (ViT) architecture to find the ground states of quantum long-range models, specifically the transverse-field…

Linear response theory for cavity QED materials at arbitrary light-matter coupling strengths
Juan Román-Roche, Álvaro Gómez-León, Fernando Luis +1
We develop a linear response theory for materials collectively coupled to a cavity that is valid in all regimes of light-matter coupling, including symmetry-broken phases. We prese…

Bound polariton states in the Dicke-Ising model
Juan Román-Roche, Álvaro Gómez-León, Fernando Luis +1
We present a study of hybrid light-matter excitations in cavity QED materials using the Dicke-Ising model as a theoretical framework. Leveraging linear response theory, we derive t…
