Exciton polaron is a hypothetical many-body quasiparticle that involves an exciton dressed
with a polarized electron-hole cloud in the Fermi sea. It has been evoked to explain the …

Recently, it has been demonstrated that the absorption of moderately doped two-
dimensional semiconductors can be described in terms of exciton polarons. In this scenario …

We experimentally demonstrate dressing of the excited exciton states by a continuously
tunable Fermi sea of free charge carriers in a monolayer semiconductor. It represents an …

Monolayer transition metal dichalcogenides (TMDs) host deeply bound excitons interacting
with itinerant electrons, and as such they represent an exciting new quantum many-body …

The interactions between charges and excitons involve complex many-body interactions at
high densities. The exciton-polaron model has been adopted to understand the Fermi sea …

Optical absorption and emission spectra of doped two-dimensional (2D) materials exhibit
sharp peaks that are often mistakenly identified with pure excitons and pure trions (or …

Polarons are quasiparticles relevant across many fields in physics: from condensed matter
to atomic physics. Here, we study the quasiparticle properties of two-dimensional strongly …

Ensembles with long-range interactions between particles are promising for revealing strong
quantum collective effects and many-body phenomena. Here we study the ground-state …

Radiative recombination of excitons dressed by the interactions with free charge carriers
often occurs under simultaneous excitation of either electrons or holes to unbound states …

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 other …
