Summary: The lattice thermal conductivity of van der Waals crystal selenium exhibits significant anisotropy, with the conductivity along the perpendicular to the chain direction being much lower than in the parallel direction, indicating quasi-one-dimensional heat transfer. Factors such as small phonon group velocity, mixing of acoustic-optical phonon branches, and bonding anharmonicity contribute to the high anisotropy in thermal conductivity in selenium. Additionally, the introduction of nanoparticles can greatly reduce the lattice thermal conductivity by introducing boundary scattering to a large portion of phonon modes.

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: By applying pressure, quasi-one-dimensional metallic properties were achieved in the three-dimensional metal halide CsSnI3. The pressure-induced hybridization between Sn-Sn and enhanced coupling between Sn-I within the chain resulted in band gap closure and the formation of conductive SnI6 distorted octahedral chains. Meanwhile, the minimal interactions between interchain I...I led to a highly anisotropic electronic structure.

Summary: This study focuses on 1D quasilattices, particularly self-similar ones, which can be used to generate quasicrystalline tessellations with matching and invertible self-similar substitution rules. The study describes the geometric constructions and equivalence classes of these quasilattices and provides explicit transformation laws between quasilattices in the same class. The study also presents ten special self-similar 1D quasilattices relevant for constructing patterns in higher dimensions and explicitly constructs the corresponding self-same quasilattices.

Summary: A new series of compounds, ANi5Bi5.6+delta (where A = K, Rb, and Cs), have been discovered with a quasi-one-dimensional (Q1D) [Ni5Bi5.6+delta]- double-walled column and a coaxial inner one-dimensional Bi atomic chain. The compounds exhibit metallic behaviors with strong electron correlation, and the Sommerfeld coefficient is enhanced with the increasing cationic radius. The substitution of Ni for Mn in ANi5Bi5.6+delta results in enhanced intercolumn distances and strong diamagnetic susceptibilities.

Summary: This paper studies the relaxation properties of phonons in 1D lattices and finds that asymmetric interparticle interactions lead to larger damping rates of phonons, which follow a power-law relation at low temperatures. This provides insights into understanding anomalous heat conduction in 1D chains and ultra-low phonon heat conduction in certain solids.

Summary: This study investigates the low temperature structural and superfluid properties of 4He confined in cylindrical nanopores using quantum Monte Carlo simulations. The results show that when the pore length greatly exceeds its radius, the 4He fluid displays remarkably one-dimensional behavior without dimensional crossover, contrary to recent claims by other authors. This system could potentially provide a viable pathway for the experimental observation of exotic behaviors, such as the junctions of interacting Tomonaga-Luttinger liquids, in a suitably designed network of nanopores.

Summary: Recent research has shown that the pair-exchange coupling between quasi-one-dimensional (Q1D) bands and conventional higher-dimensional bands in a multiband superconducting material can lead to the formation of a robust aggregate pair condensate, even with the presence of nearly shallow higher-dimensional bands. This sheds new light on the strong superconducting state observed in chain-like-structured superconducting materials A(2)Cr(3)As(3) (A = K, Rb, Cs).

Summary: Many experimentally relevant systems are quasi-one-dimensional, consisting of nearly decoupled chains, where weak interchain couplings play a crucial role in thermalizing the system. We developed a Boltzmann-equation formalism involving a collision integral that is asymptotically exact for any interacting integrable system, and applied it to study relaxation in coupled Bose gases in the Newton's cradle setup. We found that relaxation involves a broad spectrum of timescales and the Markov process governing relaxation at late times is gapless, leading to nonexponential approach to equilibrium even for spatially uniform perturbations.

Summary: A feasible approach for the assisted self-assembly of twisted layer graphene is described, utilizing a graphene origami-kirigami technique. The process involves controlled induction of wrinkle formation in single-layer graphene, followed by wrinkle folding, tearing, and re-growth. It enables the production of intertwined graphene spirals and conversion of the 1D wrinkles' chiral angle into a 2D twist angle of a 3D superlattice, offering potential for miniaturized electronic components.

Summary: Magnetic defects play a crucial role in magnetic topological insulators, influencing both the surface transport and bulk magnetic properties. In Bi2Se3-based dilute ferromagnetic (FM) TIs and MnBi2Te4-based antiferromagnetic (AFM) TIs, magnetic defects control the behavior. In Sb2Te3, a fraction of the Mn defects form strong AFM dimer singlets within a quintuple block, while in Sb1-xMnxTe3, the FM correlations are likely driven by magnetic defects in adjacent quintuple blocks.

Summary: Integrated solar flow batteries (SFBs) combine electricity generation and storage functions in one device, with high efficiency, compact design, and reduced electronics. However, their environmental performance is not well understood. This study presents the first life cycle assessment of a lab-scale SFB using a perovskite/silicon tandem photoelectrode and compares it with a competitor: a PV panel with the same tandem and a lithium manganese oxide battery. The results show that electrolytes contribute to around 59% of the environmental impacts, while the structure and PV component contribute 23% and 18% respectively. Replacing materials in the SFB's structure can significantly reduce ozone depletion and global warming potential impacts.

Summary: New pathways are needed to control the morphology and dynamics of superconducting vortex lattices in order to transform them into a computing platform. It has been discovered that nematic twin boundaries can align superconducting vortices in adjacent terraces. Different structural phases of the vortex lattice can be assumed by varying the density and morphology of the twin boundaries. These findings have implications for the design and control of strain-based topological quantum computing architectures.

Summary: In this study, we measured a 4N-periodic switching current through an asymmetric SQUID formed by the higher-order topological insulator WTe2. We found that a high asymmetry in critical current and negligible loop inductance alone were not sufficient to reliably measure the current-phase relation. Instead, we discovered that our measurement was heavily influenced by additional inductances originating from the self-formed PdTex inside the junction. We developed a method to numerically recover the current-phase relation and found that the 1.5 μm long junction was best described in the short ballistic limit. Our results highlight the complexity of subtle inductance effects that can lead to misleading topological signatures in transport measurements.

Summary: The use of work-function-mediated charge transfer is explored for nanoscale electrostatic control of atomic layers. A thin layer of a-RuCl3 is found to induce emergent nano-optical behavior in hBN through interlayer charge polarization. The propagation length of hBN phonon polaritons is significantly reduced by the interfacial dipole formed by a-RuCl3, and a novel resonance is observed in nano-optical spectroscopy experiments. These findings demonstrate the potential of charge-transfer heterostructures for tailoring optoelectronic properties of 2D insulators.

Summary: This study introduces the unique capability of tunneling Andreev reflection (TAR) to probe unconventional pairing symmetry in low-dimensional unconventional superconductors. By studying the paradigmatic FeSe superconductor, we provide direct evidence of sign-changing order parameter, reveal the existence of two superconducting gaps, and confirm the local suppression of superconductivity along the nematic twin boundary. These findings enable new atomic-scale insight into microscopic, inhomogeneous, and interfacial properties of emerging quantum materials.

Summary: This study finds that aliovalent doping can be more effective in reducing the lattice thermal conductivity of thermoelectric semiconductors compared to isoelectronic alloying. The introduction of aliovalent dopants leads to the softening and deceleration of optical phonons, resulting in a significant reduction in thermal conductivity. Moreover, the heavy dopant can induce the avoided crossing of acoustic and optical phonon branches, further suppressing phonon propagation.

Summary: Conventional spintronics-based memory devices use electrical current to control electrons' spin, but they have higher energy cost and lower endurance. To meet the demand for faster, smaller, and ultra-low-power electronic devices, research on voltage control of magnetism has intensified. Our recent efforts focus on voltage-controlled magnetism through different approaches including VCMA, VCEC, and MEC for spintronics applications. These studies have achieved large tunability of PMA, modulation of interlayer exchange coupling, and magnetism modulation via magneto-electric coupling. These findings provide routes to modulate resistance states of spintronic devices at low power and enable the development of next-generation energy-efficient computing devices.

Summary: We conducted an inelastic neutron scattering study of liquid and solid hydrogen using the wide Angular Range Chopper Spectrometer at Oak Ridge National Laboratory. Our findings show that the molecular mean-squared displacement increases with temperature near the liquid-solid phase transition, indicating the importance of thermal and quantum effects. Additionally, we observed a significant drop in kinetic energy upon melting of the crystals, which can be explained by the large increase in molar volume and Heisenberg indeterminacy principle. The results were compared with quantum Monte Carlo simulations based on different model potentials, and good agreement was found with the Silvera-Goldman and Buck potentials.

Summary: Nonionic surfactants are commonly used reagents for cell lysis and protein extraction in structural biology. However, their presence often interferes with protein analysis by electrospray ionization-mass spectrometry (ESI-MS). This study introduces a cleavable surfactant, DSSM, which is compatible with ESI-MS analysis and enables top-down proteomics characterization. DSSM can replace DDM in proteomic experiments and structural biology studies.
