TL;DR: This work observes exciton quantum beats in the optical spectrum of atomically thin ReS2, and modulates the intensity of the quantum beat signal by means of light polarisation, providing an ideal laboratory toward polarization-controlled exciton Quantum beats in two-dimensional materials.

TL;DR: In this paper, a series of ultranarrow peaks attributed to the quantum confined exciton states are observed to decrease as a function of temperature, while the linewidths demonstrate a complex and peculiar behavior, and the broadening of low energy exciton lines is governed by the radiative recombination and scattering with reservoir excitons.

TL;DR: This work shows how new opportunities to enhance on-site interactions and nonlinearities arise by tuning the exciton-polariton dipole moment in electrically biased semiconductor microcavities incorporating wide quantum wells.

TL;DR: In this article, a theory of polaritonic states for a nanostructure with a wide quantum well stressed perpendicular to the growth axis of the heterostructure is developed and the role of the $K$-linear terms appearing in the exciton Hamiltonian under the stress is discussed.

TL;DR: Experimental evidence for a nanosecond timescale spin memory based on nonradiative excitons with large in-plane wave vector is reported, attributed to the spin-dependent electron-electron exchange interaction of the optically active and inactive exciton.
