Sub-kelvin thermal conductivity of substrates and on-chip routing in quantum integrated systems

This study experimentally characterizes the sub-kelvin thermal conductivity of various substrate materials and on-chip routing, revealing that high-resistivity silicon offers superior thermal performance and that while routing lines enhance in-plane conductance, the substrate remains the dominant heat path, thereby emphasizing the critical importance of material selection and 3D integration for effective thermal management in large-scale quantum systems.

Disentangling magnetic and optical contributions in ultrafast dynamics of antiperovskite non-collinear antiferromagnets

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 $\Gamma_{4g}$ phase, whereas Mn3GaN in the $\Gamma_{5g}$ phase exhibits no such magnetic response, alongside distinct temperature-dependent quenching dynamics.

Elastic and structural anisotropy in silica thin films for gravitational-wave detectors

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.

Winding feature and thermal evolution of the Dirac magnons in CrI $_3$

Using inelastic neutron scattering on improved CrI $_3$ samples, this study reveals the magnon winding feature around the $K$ -point and a $T^2$ -renormalization behavior at elevated temperatures, thereby confirming the topological nature of Dirac magnons and clarifying their thermal evolution in this two-dimensional ferromagnet.

Superconducting and correlated phases of an effective Hubbard model on the BCC lattice

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.

On Fano effect in IR spectra of hydrogenated nanodiamonds

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.

Moire based strain analysis in wurtzite GaAs -- rock-salt (Pb,Sn)Te core-shell nanowires grown by molecular beam epitaxy

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.

An Update to Isomers of Rydberg Excitations in Argon Clusters

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.

Photon State Evolution in Arbitrary Time-Varying Media

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.
