Drive engineering in optical systems can be used to stabilize new nonlinear phases in topological systems. Dissipatively stabilized gap solitons in a polariton lattice establish drive engineering as a resource for nonlinear topological photonics.

Glitches in video calls can have a negative effect on the judgement of the people involved and correspond to worse outcomes in major areas of life such as job interviews and parole hearings.

Quantum-correlated photons typically characterize strongly nonlinear quantum emitters. A two-photon correlation spectroscopy method now provides a powerful probe of weakly nonlinear many-body quantum systems.

Cavity polaritons, arising from strong coupling between light and matter in semiconductor structures, exhibit interesting and exotic phenomena. Tanese et al. study a polariton condensate in a periodic one-dimensional microcavity and find gap soliton states, which may be useful for polaritonic circuits.

The advantage of living in cities compared with rural areas with respect to height and BMI in children and adolescents has generally become smaller globally from 1990 to 2020, except in sub-Saharan Africa.

Quantum fluids such as cavity-polaritons show nonlinear optical properties of interest in applications such as quantum optics. Here, Sturm and colleagues demonstrate an optical control of the phase of a polariton flow, and make use of this to realize a compact exciton–polariton interferometer.

The control of light–matter interactions as a way to manipulate and synthesize strongly correlated quantum matter is discussed, highlighting a field termed ‘strongly correlated electron–photon science’.

Experiments show that the dynamics of phase fluctuations  in a one-dimensional polariton condensate falls in the Kardar–Parisi–Zhang universality class, and theoretical analysis supports this finding revealing the key signatures of this universality class.

Quantum information science requires a source of entangled photon pairs, but existing sources suffer from a low intrinsic efficiency or poor extraction efficiency. Collecting emitted photons from quantum dots can be improved by coupling the dots to an optical cavity, but this is not easy for entangled photon pairs. Now, a suitable optical cavity has been made in the form of a 'photonic' molecule — two identical, connecting microcavities that are deterministically coupled to the optically active modes of a pre-selected quantum dot.

Analysis of HbA1c and FPG levels across 117 population-based studies demonstrates regional variation in prevalence of previously undiagnosed screen-detected diabetes using one or both measures and suggests that use of elevated FPG alone could underestimate diabetes prevalence in low- and middle-income countries.

From 1980 to 2018, the levels of total and non-high-density lipoprotein cholesterol increased in low- and middle-income countries, especially in east and southeast Asia, and decreased in high-income western countries, especially those in northwestern Europe, and in central and eastern Europe.

Owing to its driven-dissipative nature, and its solid-state environment, a resonantly driven polariton condensate can be accompanied by an incoherent reservoir of excitons. Stepanov et al. demonstrate that this situation strongly modifies the spectrum of collective excitations, which determines many quantum hydrodynamic features in a polariton fluid.

The localization properties of waves in the quasiperiodic chains described by the Aubry–André model and Fibonacci model are investigated. Passing from one model to the other, the system develops a cascade of delocalization transitions.

The study of Bose–Einstein condensation in photonic systems has attracted strong interest in a variety of physical platforms, including conventional lasers and optical parametric oscillators, exciton and exciton–polariton gases, and photons in dye-filled cavities and propagating geometries. The focus of this Review is to highlight those universal phenomena that stem from the driven-dissipative, non-equilibrium nature of these systems and affect the static, dynamic, superfluid and coherence properties of the condensate.

Long-lived polariton condensates can propagate well beyond the area of their initial excitation while still maintaining spatial coherence. This enables direct and controllable manipulation of the condensate wavefunction.

Giant effective photon–photon interactions are achieved by hybridizing light with excitons in an InGaAs-based quantum well micropillar cavity. Cross-phase modulation of up to 3 mrad per polariton is observed at the laser intensity below the single-photon level.

Two-photon correlation measurements in a resonantly excited fibre-cavity polariton system stay below the classical limit for zero time delay, suggesting quantum correlations between the polaritons.

Using the lifespan brain chart and two large-scale cross-cultural consortia (ABIDE and CABIC), we disentangle the heterogeneity of brain morphology in ASD into two structural impairment pathways that could disrupt sensory to association functions.

This study characterizes Notch expression and activity, comparing normal blood vessels with atherosclerotic lesions. Smooth muscle cells derived from these sources were used for signaling studies to clarify Notch activity in the diseased state. Proteomic analysis of explanted cells identified differentially expressed proteins in cells from patients with cardiovascular disease.
