TL;DR: In this paper, low temperature and polarization resolved magneto-photoluminescence experiments are used to investigate the properties of dark excitons and dark trions in a monolayer of WS2 encapsulated in hexagonal BN.

TL;DR: In this paper, it was shown that the s-type Rydberg series of excitonic states of semiconducting transition metal dichalcogenides follow a simple energy ladder: e = 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 14, 15, 16, 17, 18, 20, 21, 22, 23, 24, 25, 26, 27, 28, 28

TL;DR: This study investigates the vibrational and magnetic properties of few-layer CrBr3 using Raman scattering, revealing resonant behavior at 3.06 eV excitation and identifying five phonon modes with distinct symmetries, and observing a transition between paramagnetic and ferromagnetic states at 50 K.
Valley polarization of exciton-polaritons in monolayer WSe2 in a tunable microcavity

TL;DR: This work reports on a strong coupling regime between excitons in monolayer WSe2 and photons confined in an open, voltage-tunable dielectric microcavity that allows the tunability of the system to extend the exciton-polariton state over a wide energy range.
Intershell Exchange Interaction in Charged GaAlAs Quantum Dots
TL;DR: In this article, the optical anisotropy of charged excitons and biexcitons related to the single-particle sand p-shell emission in GaAlAs/AlAs quantum dots is investigated.
