Angle-resolved photoemission spectroscopy (ARPES), with its exceptional sensitivity to both
the binding energy and the momentum of valence electrons in solids, provides unparalleled …

The regime of strong coupling between photons and excitons gives rise to hybrid light–
matter particles with fascinating properties and powerful implications for semiconductor …

We introduce 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 …

The electron-hole exchange interaction is a fundamental mechanism that drives valley
depolarization via intervalley exciton hopping in semiconductor multivalley systems. Here …

We study systematically the role of temperature in the optical response of doped two-
dimensional semiconductors. By making use of a finite-temperature Fermi-polaron theory …

Laser-induced shift of atomic states due to the ac Stark effect has played a central role in
cold-atom physics and facilitated their emergence as analog quantum simulators. Here, we …

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 …

Monolayer transition-metal dichalcogenides (ML-TMDs) have the potential to unlock novel
photonic and chemical technologies if their optoelectronic properties can be understood and …

We study the emergent dynamics of quantum self-sustained oscillators induced by the
simultaneous presence of attraction and repulsion in the coupling path. We consider …

We present femtosecond pump-probe measurements of neutral and charged exciton optical
response in monolayer MoSe2 to resonant photoexcitation of a given exciton state in the …
