  • Principal optical axes define light-matter interactions in crystals and they are usually assumed to be stationary. Here, the authors report the observation of wavelength-dependent principal optical axes in ternary van der Waals crystals (ReS2 and ReSe2), leading to wavelength-switchable propagation directions of their waveguide modes.

  • Triggering and sustaining fusion reactions — with the goal of overall energy production — in a tokamak plasma requires efficient heating. Radio-frequency heating of a three-ion plasma is now experimentally shown to be a potentially viable technique.

  • Achieving ultrastrong coupling requires demanding experimental conditions such as cryogenic temperatures, strong magnetic fields, and high vacuum. Here, the authors use plasmon-microcavity polaritons to achieve ultrastrong coupling at ambient conditions and without the use of magnetic fields.

  • Optical anapoles in nanoresonators result in strong suppression of the electromagnetic radiation, which is challenging to detect in ideal settings. Here, the authors show that fast electrons are a powerful tool to circumvent this challenge due to their ability to access dark modes.

  • The authors combine films of two-dimensional semiconductors, which exhibit excitonic spectral features, with SiO2/Si Fabry-Perot resonators in order to realize topological phase singularities in reflection. Around these singularities, the reflection spectra demonstrate rapid phase changes while the structure behaves as a perfect absorber.

  • Gold nanoflake pairs form by self-assembly in an aqueous ligand solution and offer stable and tunable microcavities by virtue of equilibrium between attractive Casimir forces and repulsive electrostatic forces.

  • Coherent perfect absorbers (CPAs) are electromagnetic structures in which the absorption of electromagnetic energy is assisted by the interference of incident waves. This Review summarizes the fundamental principles, implementations and promising applications of CPAs for the linear control of light with light.

  • Josephson vortices (JVs) play an important role in superconducting quantum devices, but they remain difficult to be observed and manipulated. Here, Dremov et al. report magnetic fingerprint of JVs in magnetic force microscopy experiments, which paves a way to generate and control JVs.

  • Here, the authors devise a scalable method, based on anisotropic wet etching, to fabricate hexagonally shaped transition metal dichalcogenide nanostructures with smooth edges, which may serve as metamaterials with tailored optical properties.

  • The measurement of the total cross-section of proton–proton collisions is of fundamental importance for particle physics. Here, the first measurement of the inelastic cross-section is presented for proton–proton collisions at an energy of 7 teraelectronvolts using the ATLAS detector at the Large Hadron Collider.

  • The genetic code for amino acids is nearly universal, and among eukaryotic nuclear genomes the only known reassignments are of codon CUG in yeasts. Here, the authors identify a third independent CUG transition in budding yeasts that is still ongoing with alternative tRNAs present in the genome.
