Enlargement of optical Schrödinger's cat states

The amplitude of a Schrödinger's cat (SC) state — superposed coherent state — is increased using a homodyne measurement. A pair of negative SC states with amplitude of 1.15 is probabilistically converted to a single positive SC state with amplitude of 1.85.

Loss-tolerant state engineering for quantum-enhanced metrology via the reverse Hong–Ou–Mandel effect

N00N states are promising for quantum communications and metrology, but are vulnerable to losses. Here the authors develop a technique for preparing high-fidelity two-photon N00N states in a loss-free fashion, and demonstrate enhanced phase sensitivity without requiring recombination.

Observation of giant spin-split Fermi-arc with maximal Chern number in the chiral topological semimetal PtGa

Topological quasiparticle with higher Chern number is promising to realize large-quantized photogalvanic effect. Here, the authors observe splitting of both topological surface and bulk states in a chiral crystal PtGa, suggesting multifold fermions with a maximal Chern number of ±4.

Undoing the effect of loss on quantum entanglement

A protocol to recover states of optical continuous-variable entanglement is developed based on approximate heralded noiseless amplification. The degraded entanglement is completely recovered no matter how significant these losses are.

Orbital-selective effect of spin reorientation on the Dirac fermions in a non-charge-ordered kagome ferromagnet Fe₃Ge

Kagome lattices exhibit notable rich physics, however, there has been only limited study of the influence of magnetic ordering on the electronic structure. Here, by combining angle-resolved photoemission spectroscopy and first principles calculations, Lou et al. find that the spin reorientation transition has an orbital-selective effect on the Dirac fermions of the kagome material, Fe₃Ge.

Tunneling current modulation in atomically precise graphene nanoribbon heterojunctions

Here, the authors characterize the spectroscopic and transport properties of heterojunctions composed of quasi-metallic and semiconducting graphene nanoribbons (GNRs) with different widths, showing a predominant quantum tunnelling mechanism. The GNR heterojunctions can also be used to realize adsorbate sensors with high sensitivity.

Structure-based activity prediction for an enzyme of unknown function

A computational approach is used to predict the function of an uncharacterized enzyme by docking high-energy intermediate forms of candidate metabolites into its purported binding site. The docking experiments predicted that the enzyme would be able to deaminate intermediates of 5-methylthioadenosine and S-adenosylhomocysteine, a prediction confirmed by biochemical experiments and examination of the X-ray crystal structure of the protein.

Tunable positions of Weyl nodes via magnetism and pressure in the ferromagnetic Weyl semimetal CeAlSi

Topological semimetals with space-inversion and time-reversal symmetry breaking have attracted attention recently. Here, using a combination of experimental techniques and calculations, the authors demonstrate the tunability of the Weyl nodes via magnetism and pressure in the ferromagnetic Weyl semimetal CeAlSi.

Redox dynamics and surface structures of an active palladium catalyst during methane oxidation

Palladium-based catalysts are highly effective for the complete oxidation of methane. Here, the authors employ operando transmission electron microscopy, near-ambient pressure X-ray photoelectron spectroscopy, and density functional theory calculations to investigate the active state and catalytic function of Pd nanoparticles in methane oxidation.

Magnetic Dirac semimetal state of (Mn,Ge)Bi₂Te₄

Topological insulators with ordered moments of embedded magnetic atoms are viable platforms for quantum electronics, but the practical applications are restricted by the size of their crystals. The authors synthesize a Z2 topological insulator Ge_xMn_1-xBi₂Te₄ in the form of a large crystal with high structural perfection and tunable magnetic and electronic properties.

The structure of the N-terminal actin binding domain of human f imbrin offers the first view of an F-actin crosslinking protein and is representative of the conserved actin binding domain found in the largest family of crosslinking proteins. This domain is composed of two calponin homology domains and allows for the mapping of residues implicated in F-actin binding.

Acyl-chain saturation regulates the order of phosphatidylinositol 4,5-bisphosphate nanodomains

Phosphatidylinositol-4,5-bisphosphates are involved in membrane regulation and signalling in eukaryotes, with the distribution of acyl chains changing in response to stimuli. Here, molecular dynamics simulations and fluorescence spectroscopy experiments show that increasing acyl chain saturation increases the ordering of lipid nanodomains in artificial membranes.
