Robustness of quantized Hall resistivity under cavity coupling at zero temperature

Juan Román-Roche, Jie Wang, Michael Ruggenthaler +2

Recent experiments have shown that strong light-matter coupling in electromagnetic cavities can modify transport properties of quantum Hall systems through the formation of Landau…

Mumax3-cQED: an extension of Mumax3 to simulate magnon-photon interactions in cavity QED

Sergio Martínez-Losa del Rincón, Juan Román-Roche, Andrés Martín-Megino +2

We present an extension of the well-known micromagnetic package Mumax3 to simulate magnon-polaritons in realistic magnetic materials and nanostructures. Mumax3-cQED leverages the f…

First- and second-order quantum phase transitions in the long-range unfrustrated antiferromagnetic Ising chain

Víctor Herráiz-López, Sebastián Roca-Jerat, Manuel Gallego +4

We study the ground-state phase diagram of an unfrustrated antiferromagnetic Ising chain with longitudinal and transverse fields in the full range of interactions: from all-to-all…

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…

Distant emitters in ultrastrong waveguide QED: Ground-state properties and non-Markovian dynamics

Carlos A. González-Gutiérrez, Juan Román-Roche, David Zueco

Starting from the paradigmatic spin-boson model (SBM), we investigate the static and dynamical properties of a system of two distant two-level emitters coupled to a one-dimensional…
