Summary: This study demonstrates the highly tunable band gap of the layered semiconductor Zn3In2S6 under pressure, showing that the band gap widens with pressure, narrows suddenly, and finally closes under high pressure. The research reveals that the selective response of different bonds is responsible for the band gap increase at low pressure, while the pressure-induced irreversible amorphization and amorphous-amorphous transition are related to the sudden gap narrowing at high pressure.

Summary: This study presents the coexistence of ferromagnetic and antiferromagnetic spin fluctuations in UTe2, as revealed by Te-125 nuclear magnetic resonance studies. The dominant ferromagnetic spin fluctuations are found within ladders, while the antiferromagnetic spin fluctuations originate from interladder magnetic coupling. Despite the presence of antiferromagnetic spin fluctuations, the ferromagnetic spin fluctuations in ladders may play an important role in the appearance of the spin-triplet superconducting state in UTe2.

Summary: This article develops a theory of the nonlocal transport of two counterpropagating nu = 1 quantum Hall edges coupled via a narrow disordered superconductor. Contrary to predictions, the edge states proximitized in this way do not turn into a topological superconductor, but are tuned to the critical point between trivial and topological phases.

Summary: This study found that the pressure can drive the in-plane antiferromagnetic structure of EuCd2As2 across an intermediate in-plane ferromagnetic structure and then into an out-of-plane ferromagnetic structure. Butterfly-shaped magnetoresistance and anomalous Hall effect were observed under high pressure, which may support the pressure-driven ferromagnetic state. The magnetic phase transitions were not caused by structure transition or change in the Eu2+ valence state, but rather by the apparently reduced axial ratio (c/a) and compressed Eu-layer space distance. Calculations showed that the out-of-plane ferromagnetic structure only hosts one pair of Weyl nodes around the Fermi level, suggesting that pressure can be an alternative way to realize the ideal Weyl semimetal state in EuCd2As2 and explore exotic topological properties in such layered magnetic topological phase with strongly competing magnetic exchanges.

Summary: Quantum materials, especially low-dimensional ones, often exhibit competing or intertwining magnetic, electronic, and structural ordering phenomena. In the case of quasi-2D materials R4Ni3O10 (R = La, Pr), intertwined charge-and spin-density waves have been identified. However, for R = Pr, exchange coupling between the transition -metal and rare-earth sublattices leads to a dimensional crossover into a fully 3D-ordered and coupled SDW state, altering the structure of SDW on the Ni sublattice.

Summary: The nature of the superconductor-insulator transition (SIT) in thin-film disordered superconductors is still debated despite being observed more than 30 years ago. This study focuses on the insulating side of the transition and reveals that the traditional two-dimensional array model fails to explain the observed behavior. By incorporating finite relaxation time into the model, the study successfully reproduces hysteresis and multiple jumps in the current-voltage relation.

Summary: Ca-free Hg-based double-layered cuprates with Sr ions separating the two CuO2 planes exhibit bulk superconductivity at a critical temperature above 100 K. Introduction of Mo and Re atoms improves the critical current density and irreversibility field properties, possibly due to reduced thickness of the blocking layer. Replacement of Ca by Sr in the CuO2 planes does not significantly affect the temperature dependence of the irreversibility field.

Summary: Introducing spin-orbit coupling in a Josephson junction based on a newly discovered V5S8 heterodimensional superlattice leads to unusual Josephson effects. The unique homointerface of the junctions eliminates extrinsic effects caused by interfaces and disorder. Asymmetric Fraunhofer patterns are observed with respect to magnetic field and current, which are influenced by an in-plane magnetic field. Analysis of the patterns reveals a nontrivial spatial distribution of the Josephson current intrinsic to the spin-orbit coupling in V5S8.

Summary: In this study, a finite square-network based on two-dimensional crystalline superconductor Mo2C was fabricated and transport measurement was performed. Oscillations in resistance as a function of magnetic flux through the loops were observed, along with resistance dips at both matching field and fractional fillings. Temperature and current evolutions in magnetoresistance were carried out to study vortex dynamics. The interaction between thermally activated vortices and currents induced in the loops led to an enhanced amplitude of oscillation. The effective activation energy for vortex was reduced by the driving current, resulting in stronger vortex interaction. Furthermore, the effective potential barrier for vortex dissipation was derived using the thermally activated vortex creep model, showing a well-defined correspondence with structures in magnetoresistance. This work demonstrates the potential of low-dimensional crystalline superconducting networks based on Mo2C in studying vortex arrangements and dynamics, paving the way for further investigations with different configurations.

Summary: The quality of a superconductor-normal metal-superconductor Josephson junction relies on the transparency of the superconductor-normal metal interface. We present a technique for fabricating planar Josephson junctions with perfect interfaces. By utilizing the strong inverse proximity effect in Al/V5S8 bilayers, we can induce a resistive state in the Al layer. The high transparency of the homointerface and the unique normal metal allow for the flow of Josephson supercurrent across a 2.9 µm weak link. Additionally, our Josephson junction exhibits a large critical current and a significant product of the critical current and the normal state resistance.

Summary: Interlayer excitons are studied in hetero-bilayers of metal monochalcogenides, showing adjustable emission spectra and longer lifetimes compared to intralayer excitons. The bound electron-hole pair has a separation close to the calculated interfacial Se separation. These heterostacks have flat interfacial valence bands and are potential candidates for observing magnetism or other correlated electronic phases.

Summary: In this Perspective, the heuristic methods used to rationalize the stability of extended solids are discussed, with emphasis on the role of Goldschmidt's tolerance factor in perovskite research. The development of a tolerance factor for predicting the stability of intermetallic pseudoperovskites, the Remeika phases, and the correlation between oxidation states and valence fluctuation is also discussed. The feasibility of the Remeika phase tolerance factor is evaluated through the synthesis of a new predicted compound and measurement of its magnetic moment. The importance of determining the factors dictating the stability of Remeika intermetallics is highlighted.

Summary: The scaling of silicon-based transistors faces challenges such as interface imperfections and gate current leakage at sub-ten-nanometre technology nodes. To achieve smaller channel sizes, less interfacial scattering, and more efficient gate-field penetration, high-mobility two-dimensional layered semiconductors are expected as channel materials. However, progress in 2D electronics is hindered by the lack of a high dielectric constant dielectric with an atomically flat and dangling-bond-free surface.

Summary: There is a growing interest in kagome materials, which provide tunable platforms combining magnetism and electron correlation. In this study, new kagome materials Ln(x)Co(3)(Ge1-ySny)(3) (Ln = Y, Gd; y = 0.11, 0.133) were examined using the Sn flux-growth method. The Y and Gd analogues have a hybrid YCo6Ge6/CoSn structure with Sn substitution. The Gd analogue displays a magnetic moment of 8.48 mu(B), indicating contributions from both Gd and Co, while the Y analogue exhibits temperature-independent paramagnetism. Anisotropic magnetic measurements suggest that the Co magnetism is in plane with the kagome net.

Summary: In this study, we aimed to explore the mechanisms and targets of Diwu Yanggan Capsule (DWYG), a traditional Chinese medicine used in liver regeneration. We obtained the active ingredients and targets of DWYG from the TCMSP database and DEGs related to liver regeneration from the GEO database. We also searched for liver regeneration-related genes in disease databases and integrated them with the herbal and GEO data to identify potential targets of DWYG in liver regeneration. Our results revealed 73 potential targets of DWYG in liver regeneration and suggested that it may act through pathways such as MAPK, TNF, and IL-17. We also found that quercetin, a major component of DWYG, had a low binding energy to three key targets. This study highlights the potential of DWYG in facilitating liver regeneration, with quercetin possibly being its core ingredient.

Summary: Extensive studies have shown different magnetothermoelectric transport behavior in the massive Dirac material ZrTe5 compared to other Dirac materials. While thin flakes exhibit commonly observed positive magnetoresistance in a perpendicular magnetic field, they show a sharp negative magnetothermopower. In a parallel magnetic field, a negative longitudinal magnetoresistance is observed, but a remarkable positive magnetothermopower is observed for fields parallel to the thermal gradients.

Summary: In a magnetic metal, the sum of the ordinary Hall resistance and the anomalous Hall resistance is generally considered as the Hall resistance. However, this empirical relation is no longer valid when either the ordinary Hall angle or the anomalous Hall angle is not small. By using the proper conductivity relation, a B-linear magnetoresistance induced by the anomalous Hall effect (AHE) is revealed, which gives rise to a characteristic bowtie shape depending on the sign of the anomalous Hall angle. The nonlinearity of the Hall resistance in a single-band system and the appearance of a B-symmetric component in the Hall reflect the fundamental difference between the ordinary Hall effect and the AHE. Furthermore, the proposed mechanism can well explain the unusual magnetoresistance and Hall effect observed in Co3Sn2S2.
