Summary: The study presents results of molecular dynamic studies on the collective dynamics in a system of hard disks confined to a narrow quasi-one-dimensional channel. It shows that in such a quasi-1D system, transverse excitations follow specific dispersion law typical of optical transverse modes, contrasting sharply to the cases of 1D and 2D arrays of hard disks. Other peculiarities of the dispersion of collective excitations as well as some results of disk structuring and thermodynamics of the system are also discussed.

Summary: Transparent metadevices based on quasi-one-dimensional surface plasmon polariton structures offer optical and radiofrequency transparency. They can be used to create arbitrarily shaped waveguides for transmission applications and converters for radiation applications. We demonstrate the potential of this technology by constructing a wireless communication scheme for image transfer using microwave metadevices.

Summary: In this study, a spatially extended stochastic minimal model is proposed to describe the energy budget in transitional flows, taking into account the influence of flow geometry. The model successfully replicates the decay, splitting, and growth processes of localized turbulent patches in transitional flows as the Reynolds number increases. The model is also extended to quasi-one-dimensional Taylor-Couette flow, reproducing the directed percolation pattern observed in space and time.

Summary: In this study, the high insulating behavior of HfS3 was manipulated through pressure. It was found that HfS3 undergoes an insulator-to-semiconductor transition near 17 GPa, with a reduction in band gap of -1 eV. Optical absorption, Raman spectroscopy, and X-ray diffraction measurements provided consistent results, indicating the structural origin of the electronic transition. Additionally, HfS3 exhibited superconductivity at high pressure, with a record Tc of 8.1 K at 121 GPa. This work suggests that all TMTCs may have the potential to be superconductors and opens up new possibilities for exploring emergent phenomena in the TMTC material family.

Summary: The synthesized binary niobium sulfide NbS4 was found to possess a unique crystal structure with specific niobium atom coordination within chains and distinct Nb...Nb contacts. Density functional theory calculations confirmed NbS4 as a thermodynamically stable compound and a nonmagnetic semiconductor, belonging to the family of quazione-dimensional compounds. This study discussed the synthesis, crystal structure, thermal stability, and lattice dynamics of NbS4, revealing its interesting electrophysical properties.

Summary: In a recent article published in Science Bulletin, Dong et al. reported a quasi-one-dimensional TlCu3Te2 bulk material with a high application-level room temperature ZT value of 1.3. This is attributed to the presence of a pancake-like Fermi pocket with a quasi-one-dimensional dispersion at the narrow band-gap edge, as well as a large, anharmonic quasi-one-dimensional lattice structure formed by heavy Tl+ ions and weakly bonded Cu+ ions.

Summary: In this study, we investigated the angular dependence of Raman peak intensity in a ternary layered Ta2NiSe7 single crystal, identifying vibrational modes and confirming the Raman shift through first-principle calculations. The electronic band structure near the Fermi level simulated via density functional theory matched ARPES measurements, laying a useful foundation for understanding the CDW transition in Ta2NiSe7.

Summary: In this study, we observe the activation of orbital degrees of freedom in a quasi-one-dimensional system of spin-polarized fermionic potassium atoms. We measure the strength of atom-atom correlations and find a new low-energy scattering channel with even particle-exchange parity along the q1D axis. The strength and spatial symmetry of interactions are controlled by a p-wave Feshbach resonance and transverse confinement strength.

Summary: This research utilizes neutron diffraction to elucidate the exact nature of the previously unknown antiferromagnetic ground state of KMn6Bi5 and discovers transverse incommensurate spin density waves for the Mn atoms. The study also reveals a strong real space coupling between charge density waves and spin density waves, and observes a significant magnetoelastic effect during the antiferromagnetic transition.

Summary: We report the crystal growth, structural characterization, and physical properties of an off-stoichiometric van der Waals telluride Ta1.2Os0.8Te4, which is isostructural with the noncentrosymmetric WTe2, a prototypical type-II Weyl semimetal. Transport measurements have been carried out in magnetic fields up to 9 T. A low-temperature resistivity upturn is observed along all three crystallographic directions at zero field.

Summary: In this study, the growth mechanism of (NbTaTi)(0.33)S-3 nanoribbons is investigated, revealing four different growth stages and a temperature and time dependent phase evolution. Direct evidence of the charge density wave phase is provided through three-dimensional electron diffraction, and a comparison is made between different phases. This study provides valuable information for the design and synthesis of future 1D alloy structures.

Summary: In this study, we investigated the dynamics of quasiparticles and collective excitations in the material ZrTe5 using ultrafast optical pump-probe spectroscopy. Our results revealed two coherent oscillations with extremely low energies, which softened as the temperature approached two different critical temperatures. These oscillations were attributed to the amplitude mode of photoinduced dynamic charge density waves in ZrTe5. Additionally, we observed a peculiar quasiparticle decay process associated with a specific mode below a transition temperature. These findings provide important information for studying fluctuating order parameters and quasiparticle dynamics in different low-dimensional topological systems and materials.

Summary: The layered quasi one-dimensional compound TiS3 exhibits remarkable optical properties, especially photoconductivity, which is influenced by the mobility of electrons. As the temperature decreases, the photoconductivity of TiS3 increases moderately, showing semiconductor behavior above approximately 100 K and a potential phase transition into a collective state below 60 K. Additionally, a drop in electron mobility is observed around 17 K.

Summary: This study measured the transition frequencies between hyperfine levels of ground-state atoms using magnetic-resonance techniques, exploring QED effects and Casimir-Polder shifts. Calculations were conducted for hydrogen, deuterium, and tritium atoms in a metallic cavity, predicting frequency shifts that could be measurable with current magnetic resonance apparatus.
