A flatband representing a highly degenerate and dispersionless manifold state of electrons may offer unique opportunities for the emergence exotic quantum phases. To date, definitive experimental demonstrations flatbands remain to be accomplished in realistic materials. Here, we present first observation striking near Fermi level layered Fe_{3}Sn_{2} crystal consisting two Fe kagome lattices separated by Sn spacing layer. The band flatness is attributed local destructive interferences Bloch...
Lightly doped multilayer graphene surprised researchers with the emergence of superconductivity and magnetism under strong electric displacement fields. The authors interpret field versus hole-density phase diagram using mean-field theory experimentally informed band structure. They find that in these electronic systems is often intertwined nematic order because noncompact Fermi sea topology fourfold spin-valley degeneracy.
The correlation and competition between antiferromagnetism superconductivity are one of the most fundamental issues in high temperature superconductors. Superconductivity cuprate superconductors arises from suppressing an antiferromagnetic (AFM) Mott insulator1 while iron-pnictide AFM semimetals can coexist with orders2,3,4,5,6,7,8,9. This difference raises many intriguing debates on relation two classes Recently, at 32 K has been reported iron-chalcogenide AxFe2−ySe2 (A = K, Rb Cs)10,11,12....
The large amount of 4-nitrophenol (4-NP) wastewater produced by the chemical industry has received increased concern over growing risk environmental pollution. ability to catalyze reduction highly concentrated 4-NP is desirable for practical treatment industrial wastewater, yet it remains a significant challenge. Herein, we report Pd nanoparticle-decorated 3D-printed hierarchically porous TiO2 scaffolds (Pd/TiO2 scaffolds) efficient (2 g·L-1, ∼14.38 mM). millimeter-sized interconnected...
It has recently been shown [Y. Cao, J. M. Park, K. Watanabe, T. Taniguchi, and P. Jarillo-Herrero, Pauli-limit violation re-entrant superconductivity in moir\'e graphene, Nature (London) 595, 526 (2021).] that magic-angle twisted trilayer graphene survives to in-plane magnetic fields are well excess of the Pauli limit, much stronger than critical bilayer graphene. The difference is surprising because bilayers trilayers both support flat bands thought be fountainhead superconductivity. We...
We employ a functional renormalization group approach to ascertain the pairing mechanism and symmetry of superconducting phase observed in rhombohedral trilayer graphene. Superconductivity this system occurs regime carrier density displacement field with weakly distorted annular Fermi sea. find that repulsive Coulomb interactions can induce electron on surface by taking advantage momentum-space structure associated finite width sea annulus. The degeneracy between spin-singlet spin-triplet is...
The observation of substantially enhanced superconductivity single-layer FeSe films on ${\mathrm{SrTiO}}_{3}$ has stimulated intensive research interest. At present, conclusive experimental data the corresponding electron-boson interaction is still missing. Here we use inelastic electron scattering spectroscopy and angle resolved photoemission to show that electrons in these systems are dressed by strongly polarized lattice distortions ${\mathrm{SrTiO}}_{3}$, indispensable nonadiabatic...
We construct a continuum model of twisted trilayer graphene using {\it ab initio} density-functional-theory calculations, and apply it to address electronic structure. Our accounts for moir\'e variation in site energies, hopping between outside layers within layers. focus on the role mirror symmetry present ABA trilayers with middle layer twist.

Graphene is a promising material for designing next-generation electronic and valleytronic devices, which often demand the opening of bandgap in otherwise gapless pristine graphene. To date, several conceptually different mechanisms have been extensively exploited to induce bandgaps graphene, including spin–orbit coupling inversion symmetry breaking monolayer quantum confinement graphene nanoribbons (GNRs). Here, we present multiscale study competing gap overlayer GNRs proximity-coupled...
The microscopic mechanism of superconductivity in magic-angle twisted bilayer graphene (MATBG) is currently under active debate. authors propose here that valuable constraints are implied by the band-filling dependences critical temperature and magnetic field, which together define an average Fermi velocity. They show a robust inverse correlation between velocity holds models with independent pairing interactions. absence such association experiments suggests glue MATBG strongly dependent.
Abstract Utilizing hot carriers for efficient plasmon‐mediated chemical reactions (PMCRs) to convert solar energy into secondary is one of the most feasible solutions global environmental and crisis. Finding a plasmonic heterogeneous nanostructure with more reasonable carrier transport path without affecting intrinsic properties still major challenge that urgently needs be solved in this field. Herein, mechanism by which plasmon‐promoted interatomic electron redistribution on surface Au 3 Cu...
Abstract As China experiences a dramatic surge in carbon emissions from the transportation sector, reducing these has become crucial mitigating climate change. Since 2020, Navigation Service Providers collaborated with traffic police departments to integrate “Traffic Light Countdown” module (TLCM) navigation applications multiple cities across China, including Beijing, Chongqing and Jinan. This initiative aims improve vehicle efficiency, reduce emissions, enhance public driving safety...
Half-metallic materials allow electrons with one spin orientation to conduct through, while completely blocking the other orientation. Here we use a multiscale approach predict that ${\mathrm{MnSiTe}}_{3}$ within transition metal trichalcogenide (TMT) family is an intrinsic layered half-metal both in bulk form and at ultrathin two-dimensional (2D) limit. We first first-principles calculations demonstrate system van der Waals crystal weak interlayer coupling, allowing ready separation of...
We present a theory of superconductivity in twisted bilayer graphene which attraction is generated between electrons on the same honeycomb sublattice when system close to polarization instability. The resulting Cooper pairs are spin-polarized valley singlets. Because polarizability mainly contributed by interband fluctuations, occurs over wide range filling fraction. It suppressed (i) applying polarizing field (generated an aligned BN substrate) or (ii) changing moir\'e band favor...

Ferroelectricity, superconductivity, and topology are three cornerstone concepts of condensed matter physics, integration any two may further fertilize exotic emergent phenomena. To date, harmonic coexistence all remains to be materialized. Here, the authors predict simultaneous tuning superconducting transition temperature band by ferroelectricity, with a heterobilayer IrTe${}_{2}$ ferroelectric In${}_{2}$Se${}_{3}$ as physically realistic example. Such reversible nonvolatile tunabilities...
Recent advances in realizing ferroelectric and superconducting two-dimensional heterobilayers provide appealing platforms for exploring the interplay between ferroelectricity superconductivity, which is not only crucial understanding mechanism but also important designing next-generation devices. Based on first-principles calculations, we demonstrate that an ${\mathrm{IrTe}}_{2}$ monolayer can be stabilized a ${\mathrm{In}}_{2}{\mathrm{Se}}_{3}$ via interlayer coupling. The transition...
