This study reports the electrochemical reduction of hydrogen-capped polyynes to synthesize stable, amorphous sp-sp2 carbon nanoparticles with tunable diameters and high sp-character retention, offering a pathway toward 0-D sp-sp2 nanostructures and potential quantum-dot applications.
This study utilizes ultrafast pump-probe experiments and optical modeling to disentangle magnetic and optical contributions in antiperovskite non-collinear antiferromagnets, revealing that field-dependent magnetooptical signals in Mn3NiN arise from piezomagnetic domain redistribution in its phase, whereas Mn3GaN in the phase exhibits no such magnetic response, alongside distinct temperature-dependent quenching dynamics.
Using Brillouin light scattering and infrared reflectivity, this study reveals that ion-beam-sputtered silica films exhibit significant elastic anisotropy that persists after standard 500°C heat treatment but is eliminated at 900°C, suggesting that restoring isotropy through high-temperature annealing could reduce thermal noise in future gravitational-wave detector coatings.
Using inelastic neutron scattering on improved CrI samples, this study reveals the magnon winding feature around the -point and a -renormalization behavior at elevated temperatures, thereby confirming the topological nature of Dirac magnons and clarifying their thermal evolution in this two-dimensional ferromagnet.
This paper investigates the electronic phases of an effective Hubbard model on a body-centered-cubic lattice, motivated by alkali-doped fullerides, by employing complementary theoretical approaches in intermediate and strong coupling regimes to reveal first-order transitions between superconducting, antiferromagnetic, and Mott insulating states.
This work investigates the origin of the Fano-resonance "transmission window" in the infrared spectra of hydrogenated nanodiamonds and concludes that while adsorbed C-H stretching vibrations are not responsible, the resonance likely arises from the coupling of diamond optical phonons with either monohydride bending vibrations on (111) surfaces or graphitic islands, depending on the specific morphology and size distribution of the grains.
This study utilizes high-resolution transmission electron microscopy and geometric phase analysis to investigate lattice-mismatch-induced misfit dislocations and moiré fringes in molecular beam epitaxy-grown wurtzite GaAs/(Pb,Sn)Te core-shell nanowires, demonstrating that moiré pattern analysis serves as an effective alternative method for estimating strain in these topological crystalline insulator structures.
This paper reports an improved Diatomic-In-Molecules (DIM) calculation for excited argon clusters that incorporates previously ignored strongly avoided crossings between 3p4s and 3p4p states to better understand the localization of excitation and the effect of diabatisation on cluster isomers.
This contribution presents an efficient "instantaneous eigenstate method" based on the Heisenberg equation to analyze the evolution of photon states in arbitrary time-varying media, demonstrating that the generation of single photon pairs from the vacuum is limited to a probability of 25%, whereas Bell states can reach 84%, and showcasing precise control over photon spectral profiles through temporal modulation of material properties.
This paper introduces PdNeuRAM, a novel forming-free, multi-bit Pd/HfO2 ReRAM device that leverages a unique Pd-O-Hf configuration to eliminate electroforming, reduce variability, and significantly lower programming and reading energy for efficient neuromorphic computing.
