The study shows a micron-scale polariton structure where an artificial gauge field creates topological, non-reciprocal edge transport without strong magnetic fields, overcoming key limits for topological polariton lasers and devices.

Surface controls nanocrystal growth, but atomic-scale hard-soft interfaces are hard to measure. Here, the authors develop electron microscopy methods to reveal the position of metal adatoms and surfactant counterions on gold nanocuboid surfaces.

Strongly coupled light–matter systems could offer enhanced manipulation of topological phenomena. Now, tunable non-Hermitian effects are demonstrated with exciton–polaritons induced by a twist degree of freedom.

The authors implement on-chip Rydberg exciton-polaritons by coupling WS₂ monolayers to a photonic crystal. Rydberg polaritons exhibit a nonlinearity of 8.0 ± 2.3 times larger than that of the ground polaritonic states due mostly to their extended exciton radii and photonic crystal-induced spatially localized electric field distribution.

The authors embed a multiple quantum-well WS₂ heterostructure in a planar microcavity and show the systematic control of the normal mode coupling-strength. They find a strong enhancement of the characteristic time scale, which they attribute to long-lived dark excitations emerging in the structure.

Constrained molecules typically adopt one major conformation and this limitation prevents the study of other energetically less-favourable conformations. Nevertheless, these alternate structures might prove to be useful and it has now been shown that a dominant rotor method can alter the energetic landscape of peptides to create two-well systems with distinct conformational behaviour.

Polaritonics is the physics of strongly coupled light–matter states that studies condensates and superfluids of bosonic quasiparticles in solid-state systems.
