Photon-mediated interactions by Floquet photonic lattices
Jia-Qiang Chen, Peng-Bo Li, Álvaro Gómez-León +1
We investigate the interactions between two-level emitters mediated by time-dependent, one-dimensional, structured photonic baths, focusing on Floquet topological lattices. Buildin…
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…
Anomalous Floquet Phases. A resonance phenomena
Álvaro Gómez-León
Floquet topological phases emerge when systems are periodically driven out-of-equilibrium. They gained attention due to their external control, which allows to simulate a wide vari…
Driven-dissipative topological phases in parametric resonator arrays
Álvaro Gómez-León, Tomás Ramos, Alejandro González-Tudela +1
We study the phenomena of topological amplification in arrays of parametric oscillators. We find two phases of topological amplification, both with directional transport and expone…
Decimation technique for open quantum systems: a case study with driven-dissipative bosonic chains
Álvaro Gómez-León, Tomás Ramos, Diego Porras +1
The unavoidable coupling of quantum systems to external degrees of freedom leads to dissipative (non-unitary) dynamics, which can be radically different from closed-system scenario…
