Coupled-channel approach to scattering of hybrid excitons
Yasufumi Nakano, Meera M. Parish, Jesper Levinsen
We consider the interactions of hybrid excitons in a two-dimensional semiconductor bilayer, where spatially direct and indirect excitons are hybridized by interlayer charge-carrier…
Few is different: deciphering many-body dynamics in mesoscopic quantum gases
Juergen Berges, Sandra Brandstetter, Jasmine Brewer +27
Emergent macroscopic descriptions of matter, such as hydrodynamics, are central to our description of complex physical systems across a wide spectrum of energy scales. The conventi…
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…
Role of impurity statistics and medium constraints in polaron-polaron interactions
Jesper Levinsen, Francesca Maria Marchetti, Olivier Bleu +1
We consider the behavior of a small density of mobile impurities (polarons) immersed in a quantum gas, a generic scenario that can be realized in cold atomic gases, liquid helium m…
Quantum Droplets of Light in Semiconductor Microcavities
Matteo Caldara, Olivier Bleu, Francesca Maria Marchetti +2
Quantum droplets are dilute self-bound configurations of bosons that result from the balance between a mean-field attraction and a repulsion induced by quantum fluctuations. Such d…
