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…
First- and second-order quantum phase transitions in the long-range unfrustrated antiferromagnetic Ising chain
VÃctor 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, Ãlvaro 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, Ãlvaro 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…
Mumax3-cQED: an extension of Mumax3 to simulate magnon-photon interactions in cavity QED
Sergio MartÃnez-Losa del Rincón, Juan Román-Roche, Andrés MartÃn-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…
