Room-temperature tuning and probing of Fermi polarons in atomically thin semiconductors on a plasmonic metasurface
Tingting Wu, Francesca Maria Marchetti, Antonio Tiene +9
The Fermi polaron, arising from interactions between a mobile impurity and a degenerate Fermi sea, is a many-body quasiparticle that provides a sensitive probe of strongly correlat…
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…
Optical properties of Fermi polarons in a GaInP/MoSe2 monolayer heterostructure
Hangyong Shan, Max Waldherr, Diksha Diksha +15
Engineering optical properties, such as luminescence purity and charge transfer, is crucial for harnessing the application potential of atomically thin transition metal dichalcogen…
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…
Efficient calculation of trion energies in monolayer transition metal dichalcogenides
Sangeet S. Kumar, Brendan C. Mulkerin, Antonio Tiene +3
The reduced dielectric screening in atomically thin semiconductors leads to remarkably strong electron interactions. As a result, bound electron-hole pairs (excitons) and charged e…

D. de la Fuente Pico, J. Levinsen, E. Laird +2
We develop a microscopic theory for excitons and cavity exciton polaritons in transition metal dichalcogenide (TMD) monolayers under a perpendicular static magnetic field. We obtai…
Multiple polaron quasiparticles with dipolar fermions in a bilayer geometry
A. Tiene, A. Tamargo Bracho, M. M. Parish +2
We study the Fermi polaron problem with dipolar fermions in a bilayer geometry, where a single dipolar particle in one layer interacts with a Fermi sea of dipolar fermions in the o…

We present a quantum virial expansion for the optical response of a doped two-dimensional semiconductor. As we show, this constitutes a perturbatively exact theory in the high-temp…

A. Muñoz de las Heras, M. M. Parish, F. M. Marchetti
We study the early-time dynamics of a degenerate Bose gas after a sudden quench of the interaction strength, starting from a weakly interacting gas. By making use of a time-depende…

Superfluidity, the ability of a liquid or gas to flow with zero viscosity, is one of the most remarkable implications of collective quantum coherence. In equilibrium systems like l…
