Interfacial Mirror Symmetry Breaking Induced Helicity-Dependent Photocurrents in hBN/CrPS Heterostructure.

Research on quantum geometric-related effects in antiferromagnetic van der Waals heterostructures has predominantly focused on separating the contributions of Berry curvature and quantum metric through the manipulation of Parity-Time (PT) symmetry. However, the critical role of interfacial symmetry-breaking mechanisms, particularly those emerging from parity inversion symmetry manipulation, has remained underexplored. This study advances the field by investigating the hBN/CrPS heterojunction, where the mirror symmetry at the interface is systematically controlled.

Reactive molecular beam epitaxial growth of RuOsuperconducting thin films.

RuOis remarkable not only for its strain-stabilized superconductivity, but also for being theoretically predicted to be an altermagnet, a third form of magnetism characterized by antiferromagnetism-like magnetic order with zero net magnetization, while exhibiting ferromagnetism-like lifted Kramers spin degeneracy in reciprocal space. Here, we have synthesized high-quality RuOfilms on TiO(110) substrates by reactive molecular beam epitaxy and thoroughly investigated their electronic structure. Through improving the quality of the interface, the transition temperature of superconductivity in the strained films increased significantly.

Polarization Sensitive Vacuum-Ultraviolet Photodetectors Based on m-Plane h-BN.

Vacuum ultraviolet (VUV) detection plays an essential role in space science, radiation monitoring, electronic industry, and fundamental research. Integrating polarization characteristics into VUV detection enriches the comprehension of the target attributes and broadens the signal dimensionality. Polarization detection has been widely developed in visible and infrared regions; however, it is still relatively unexplored in VUV light due to the lack of photoactive materials with low-symmetry structures, VUV selective response and radiation resistance.

Electronic structure of superconducting infinite-layer lanthanum nickelates.

Revealing the momentum-resolved electronic structure of infinite-layer nickelates is essential for understanding this class of unconventional superconductors but has been hindered by the formidable challenges in improving the sample quality. In this work, we report the angle-resolved photoemission spectroscopy of superconducting LaSrNiO films prepared by molecular beam epitaxy and in situ atomic-hydrogen reduction. The measured Fermi topology closely matches theoretical calculations, showing a large Ni [Formula: see text]-derived Fermi sheet that evolves from hole-like to electron-like along and a three-dimensional (3D) electron pocket centered at the Brillouin zone corner.

Large Band Splitting in g-Wave Altermagnet CrSb.

Altermagnetism (AM), a newly discovered magnetic state, ingeniously integrates the properties of ferromagnetism and antiferromagnetism, representing a significant breakthrough in the field of magnetic materials. Despite experimental verification of some typical AM materials, such as MnTe and MnTe_{2}, the pursuit of AM materials that feature larger spin splitting and higher transition temperature is still essential. Here, our research focuses on CrSb, which possesses Néel temperature of up to 700 K and giant spin splitting near the Fermi level (E_{F}).

Absence of Altermagnetic Spin Splitting Character in Rutile Oxide RuO_{2}.

Rutile RuO_{2} has been posited as a potential d-wave altermagnetism candidate, with a predicted significant spin splitting up to 1.4 eV. Despite accumulating theoretical predictions and transport measurements, direct spectroscopic observation of spin splitting has remained elusive.

How mesenchymal stem cells transform into adipocytes: Overview of the current understanding of adipogenic differentiation.

Mesenchymal stem cells (MSCs) are stem/progenitor cells capable of self-renewal and differentiation into osteoblasts, chondrocytes and adipocytes. The transformation of multipotent MSCs to adipocytes mainly involves two subsequent steps from MSCs to preadipocytes and further preadipocytes into adipocytes, in which the process MSCs are precisely controlled to commit to the adipogenic lineage and then mature into adipocytes. Previous studies have shown that the master transcription factors C/enhancer-binding protein alpha and peroxisome proliferation activator receptor gamma play vital roles in adipogenesis.

Flat bands, non-trivial band topology and rotation symmetry breaking in layered kagome-lattice RbTiBi.

A representative class of kagome materials, AVSb (A = K, Rb, Cs), hosts several unconventional phases such as superconductivity, [Formula: see text] non-trivial topological states, and electronic nematic states. These can often coexist with intertwined charge-density wave states. Recently, the discovery of the isostructural titanium-based single-crystals, ATiBi (A = K, Rb, Cs), which exhibit similar multiple exotic states but without the concomitant charge-density wave, has opened an opportunity to disentangle these complex states in kagome lattices.

Utilizing the micron-scale spatially resolved angle-resolved photoemission spectroscopy and first-principles calculations, we report a systematical study of the electronic structures ofV6Sn6(= Gd, Tb, and Lu) on the two cleaved surfaces, i.e.

Observation of Electronic Nematicity Driven by the Three-Dimensional Charge Density Wave in Kagome Lattice KVSb.

Kagome superconductors AVSb (A = K, Rb, Cs) provide a fertile playground for studying intriguing phenomena, including nontrivial band topology, superconductivity, giant anomalous Hall effect, and charge density wave (CDW). Recently, a symmetric nematic phase prior to the superconducting state in AVSb drew enormous attention due to its potential inheritance of the symmetry of the unusual superconductivity. However, direct evidence of the rotation symmetry breaking of the electronic structure in the CDW state from the reciprocal space is still rare, and the underlying mechanism remains ambiguous.

Electronic structure and layer-dependent magnetic order of a new high-mobility layered antiferromagnet KMnBi.

Room-temperature two-dimensional antiferromagnetic (AFM) materials are highly desirable for various device applications. In this letter, we report the low-energy electronic structure of KMnBi measured by angle-resolved photoemission spectroscopy, which confirms an AFM ground state with the valence band maximum located at -100 meV below the Fermi level and small hole effective masses associated with the sharp band dispersion. Using complementary Raman, atomic force microscope and electric transport measurement, we systematically study the evolution of electric transport characteristics of micro-mechanically exfoliated KMnBi with varied flake thicknesses, which all consistently reveal the existence of a probable AFM ground state down to the quintuple-layer regime.

Avian Angara disease caused by fowl adenovirus serotype 4 (FAdV-4) has spread widely and brought economic losses to the poultry industry in some countries. Effective vaccines for Angara disease control are currently lacking. In this study, four capsid proteins (hexon, penton, fiber1 and fiber2) from FAdV-4 were selected, and their optimal efficient antigenic epitopes predicted by bioinformatics software were tandemly linked with the flexible linker GGGGS.

Direct Observation of the Topological Surface State in the Topological Superconductor 2M-WS.

The quantum spin Hall (QSH) effect has attracted extensive research interest because of the potential applications in spintronics and quantum computing, which is attributable to two conducting edge channels with opposite spin polarization and the quantized electronic conductance of 2/. Recently, 2M-WS, a new stable phase of transition metal dichalcogenides with a 2M structure showing a layer configuration identical to that of the monolayer 1T' TMDs, was suggested to be a QSH insulator as well as a superconductor with a critical transition temperature of around 8 K. Here, high-resolution angle-resolved photoemission spectroscopy (ARPES) and spin-resolved ARPES are applied to investigate the electronic and spin structure of the topological surface states (TSS) in the superconducting 2M-WS.

Dimensionality-Controlled Evolution of Charge-Transfer Energy in Digital Nickelates Superlattices.

Fundamental understanding and control of the electronic structure evolution in rare-earth nickelates is a fascinating and meaningful issue, as well as being helpful to understand the mechanism of recently discovered superconductivity. Here the dimensionality effect on the ground electronic state in high-quality (NdNiO ) /(SrTiO ) superlattices is systematically studied through transport and soft X-ray absorption spectroscopy. The metal-to-insulator transition temperature decreases with the thickness of the NdNiO slab decreasing from bulk to 7 unit cells, then increases gradually as m further reduces to 1 unit cell.

Giant moiré trapping of excitons in twisted hBN.

Excitons in van der Waals (vdW) stacking interfaces can be trapped in ordered moiré potential arrays giving rise to the attractive phenomena of quantum optics and bosonic many-body effects. Compared to the prevalent transition metal dichalcogenides (TMDs) systems, due to the wide bandgap and low dielectric constant, excitons in twist-stacked hexagonal boron nitride (hBN) are anticipated trapped in deeper moiré potential, which enhances the strength of interactions. However, constrained by the common low detectivity of weak light-emitting in the deep-ultraviolet (DUV) bands, the moiré excitons in twist-hBN remain elusive.

Directed exfoliating and ordered stacking of transition-metal-dichalcogenides.

Two-dimensional van der Waals crystals provide a limitless scope for designing novel combinations of physical properties by controlling the stacking order or twist angle of individual layers. Lattice orientation between stacked monolayers is significant not only for breaking the engineering symmetry but also for the study of many-body quantum phases and band topology. Thus far the state-of-the-art exfoliation approaches focus on the achievements of quality, size, yield, and scalability, while lacking sufficient information on lattice orientation.

Emergence of New van Hove Singularities in the Charge Density Wave State of a Topological Kagome Metal RbV_{3}Sb_{5}.

Quantum materials with layered kagome structures have drawn considerable attention due to their unique lattice geometry, which gives rise to flat bands together with Dirac-like dispersions. Recently, vanadium-based materials with layered kagome structures were discovered to be topological metals, which exhibit charge density wave (CDW) properties, significant anomalous Hall effect, and unusual superconductivity at low temperatures. Here, we employ angle-resolved photoemission spectroscopy to investigate the electronic structure evolution upon the CDW transition in a vanadium-based kagome material RbV_{3}Sb_{5}.

Understanding the mechanisms underlying malignancy in myeloma cells is important for targeted treatment and drug development. Histone deacetylases (HDACs) can regulate the progression of various cancer types; however, their roles in myeloma are not well known. In the present study, the expression of class I HDACs in myeloma cells and tissues was evaluated.

Electron-plasmon interaction induced plasmonic-polaron band replication in epitaxial perovskite SrIrO films.

Electron-boson interaction is fundamental to a thorough understanding of various exotic properties emerging in many-body physics. In photoemission spectroscopy, photoelectron emission due to photon absorption would trigger diverse collective excitations in solids, including the emergence of phonons, magnons, electron-hole pairs, and plasmons, which naturally provides a reliable pathway to study electron-boson couplings. While fingerprints of electron-phonon/-magnon interactions in this state-of-the-art technique have been well investigated, much less is known about electron-plasmon coupling, and direct observation of the band renormalization solely due to electron-plasmon interactions is extremely challenging.

Spontaneous phase segregation of SrNiO and SrNiO during SrNiO heteroepitaxy.

Recent discovery of superconductivity in NdSrNiO motivates the synthesis of other nickelates for providing insights into the origin of high-temperature superconductivity. However, the synthesis of stoichiometric Sr NiO thin films over a range of has proven challenging. Moreover, little is known about the structures and properties of the end member SrNiO Here, we show that spontaneous phase segregation occurs while depositing SrNiO thin films on perovskite oxide substrates by molecular beam epitaxy.
