Authors: Alushi, Uesli; Ramos, Tomas; Garcia-Ripoll, Juan Jose; Di Candia, Roberto; Felicetti, Simone Journal: PRX QUANTUM Publication date: 2023/08/25 DOI: 10.1103/PRXQuantum.4.030326 Abstract: Quadratic light-matter interactions are nonlinear couplings such that quantum emitters interact with photonic or phononic modes exclusively via the exchange of excitation pairs. Implementable with atomic and solid-state systems, these couplings lead to [...]

Authors: Vega, C.; Porras, D.; Gonzalez-Tudela, A. Journal: PHYSICAL REVIEW RESEARCH Publication date: 2023/04/17 DOI: 10.1103/PhysRevResearch.5.023031 Abstract: Topological insulators feature a number of topologically protected boundary modes linked to the value of their bulk invariant. While in one-dimensional systems the boundary modes are zero dimensional and localized, in two-dimensional topological insulators the boundary modes are [...]
