Polaritons are quasiparticles that form in semiconductors when an elementary excitation
such as an exciton or a phonon interacts sufficiently strongly with light. In particular, exciton …

Microcavities are semiconductor, metal, or dielectric structures providing optical confinement
in one, two or three dimensions. At the end of the 20th century, microcavities have attracted …

Semiconductor microcavities offer unique systems in which to investigate the physics of
weakly interacting bosons. Their elementary excitations, polaritons—mixtures of excitons …

Polariton lasers are coherent emitters in which the fundamental constituents are not photons
amplified by a gaining medium but hybrid, part exciton and part photon, quasi-particles …

Two-dimensional semiconductors provide an ideal platform for exploration of linear exciton
and polariton physics, primarily due to large exciton binding energy and strong light-matter …

In the past decade, there has been a burst of new and fascinating physics associated to the
unique properties of two-dimensional exciton polaritons, their recent demonstration of …

Light-matter interaction has played a central role in understanding as well as engineering
new states of matter. Reversible coupling of excitons and photons enabled groundbreaking …

It is widely assumed that photons cannot be manipulated using electric or magnetic fields.
Even though hybridization of photons with electronic polarization to form exciton-polaritons …

Recent experiments have shown that polaritons in microcavities behave like a Bose-Einstein
condensate above a critical density threshold and at low temperature. The polaritons are not …

We report on the experimental evidence for a nanosecond timescale spin memory based on
nonradiative excitons with large in-plane wave vector. The effect manifests itself in magnetic …
