Interacting many-body systems display enhanced sensitivity close to critical transition points
due to diverging quantum fluctuations. This criticality-based enhancement has been …

The past 30 years have witnessed remarkable developments of microcavity exciton–
polaritons, which have made a great impact on photonics and optoelectronics from …

Exceptional points (EPs)—spectral singularities of non-Hermitian linear systems—have
recently attracted interest for sensing. While initial proposals and experiments focused on …

In this work, we explore the intriguing phenomena of bistability and multistability in a cavity
comprising two coupled quantum wells via electron tunneling. The cavity is driven by …

We investigate, experimentally and theoretically, the dynamics of a laser-driven cavity with
noninstantaneous effective photon-photon interactions. Scanning the laser-cavity frequency …

Interferometric measurements of an optically trapped exciton-polariton condensate reveal a
regime where the condensate pseudo-spin precesses persistently within the driving optical …

We investigate non-Hermitian spectrum and multistability of exciton-polariton condensates
excited by a nonresonant pump. An increase in pum** power moves the system away …

Cavity exciton polariton physics and cavity optomechanics have evolved into mature and
active domains with, so far, very little connections between them. We argue here that there …

We investigate the spin behavior of the first excited state of a polariton condensate in an
optical trap by means of polarization resolved spectroscopy. The interplay between the …

In this paper, the low-threshold optical bistability (OB) of a reflected light beam at terahertz
frequencies is achieved by using a multilayer structure where monolayer graphene is coated …
