Magnetic-field driven hybridization of heavy- and light-hole Rydberg excitons in GaAs quantum wells
David de la Fuente Pico, Johannes Bürger, Antonio Gianfrate +5
We present a combined theoretical and experimental study of ground and excited Rydberg exciton states in wide GaAs quantum wells exposed to a magnetic field in the Faraday geometry…
Very strong light-matter coupling in patterned GaAs heterostructures
David de la Fuente Pico, Johannes Bürger, Antonio Gianfrate +5
The very strong light-matter coupling regime enables the non-perturbative modification of matter properties via light. Using a patterned GaAs/AlGaAs waveguide with twelve wide quan…
Emerging supersolidity from a polariton condensate in a photonic crystal waveguide
Dimitrios Trypogeorgos, Antonio Gianfrate, Manuele Landini +10
A supersolid is a counter-intuitive phase of matter where its constituent particles are arranged into a crystalline structure, yet they are free to flow without friction. This requ…
Exciton-polariton ring Josephson junction
Nina Voronova, Anna Grudinina, Riccardo Panico +6
Macroscopic coherence in quantum fluids allows the observation of interference effects in their wavefunctions, and enables applications such as superconducting quantum interference…
Direct measurement of the quantum geometric tensor in a two-dimensional continuous medium
A. Gianfrate, O. Bleu, L. Dominici +8
Topological Physics relies on the specific structure of the eigenstates of Hamiltonians. Their geometry is encoded in the quantum geometric tensor containing both the celebrated Be…
Tunable out-of-plane excitons in 2D single crystal perovskites
A. Fieramosca, L. De Marco, M. Passoni +11
Hybrid organic-inorganic perovskites have emerged as very promising materials for photonic applications, thanks to the great synthetic versatility that allows to tune their optical…
