As the two most representative operation modes in an optical imaging system, bright-field and phase contrast can extract different morphological information on object. Developing a miniature low-cost system capable of switching between these is thus very attractive for number applications, such as biomedical imaging. Here, we propose demonstrate that Fourier transform setup incorporating all-dielectric metasurface perform two-dimensional spatial differentiation achieve isotropic edge...
Monochromatic light can be characterized by its three fundamental properties: amplitude, phase, and polarization. In this work, we propose a versatile, transmission-mode all-dielectric metasurface platform that independently manipulate the phase amplitude for two orthogonal states of polarization in visible frequency range. For proof-of-concept experimental demonstration, various single-layer metasurfaces composed subwavelength-spaced titanium-dioxide nanopillars are designed, fabricated, to...
Exquisite polarization control using optical metasurfaces has attracted considerable attention thanks to their ability manipulate multichannel independent wavefronts with subwavelength resolution. Here we present a new class of metasurface optics, which enables imposition two arbitrary and amplitude profiles on any pair orthogonal states polarization. The implementation method involves polarization-dependent interference mechanism achieved by constructing composed an array nanoscale...
The newly discovered high-temperature superconductivity in La_{3}Ni_{2}O_{7} under pressure has attracted a great deal of attention. essential ingredient characterizing the electronic properties is bilayer NiO_{2} planes coupled by interlayer bonding 3d_{z^{2}} orbitals through intermediate oxygen atoms. In strong coupling limit, low-energy physics described an intralayer antiferromagnetic spin-exchange interaction J_{∥} between 3d_{x^{2}-y^{2}} and one J_{⊥} orbitals. Taking into account...
Polarization, one of the fundamental properties light, is critical for certain imaging applications because it captures information from scene that cannot directly be recorded by traditional intensity cameras. Currently, mainstream approaches polarization rely on strong dichroism birefringent crystals or artificially fabricated structures exhibit a high diattenuation typically exceeding 99%, which corresponds to extinction ratio (PER) >~100. This not only limits transmission efficiency but...
Abstract Dielectric metasurfaces, composed of planar arrays subwavelength dielectric structures that collectively mimic the operation conventional bulk optical elements, have revolutionized field optics by their potential in constructing high-efficiency and multi-functional optoelectronic systems on chip. The performance a metasurface is largely determined its constituent material, which highly desired to high refractive index, low loss wide bandgap, at same time, be fabrication friendly....
Quantum computers need new materials to protect their delicate quantum states. Evidence for such a material---a topological superconductor---has been detected as breaking of rotational symmetry in crystal Nb-doped Bi${}_{2}$Se${}_{3}$.
Phonons are known to generate a thermal Hall effect in certain insulators, including oxides with rare-earth impurities, quantum paraelectrics, multiferroic materials and cuprate Mott insulators. In each case, special feature of the material is presumed relevant for underlying mechanism that confers chirality phonons magnetic field. The question whether phonon an unusual occurrence - linked characteristics such as skew scattering off structural domains, ferroelectricity, ferromagnetism or...
Materials tuned to a quantum critical point display universal scaling properties as function of temperature $T$ and frequency $\omega$. A long-standing puzzle regarding cuprate superconductors has been the observed power-law dependence optical conductivity with an exponent smaller than one, in contrast $T$-linear resistivity $\omega$-linear scattering rate. Here, we present analyze La$_{2-x}$Sr$_x$CuO$_4$ $x=0.24$. We demonstrate $\hbar\omega/k_{\mathrm{B}} T$ data over wide range...

In metals, orbital motions of conduction electrons on the Fermi surface are quantized in magnetic fields, which is manifested by quantum oscillations electrical resistivity. This Landau quantization generally absent insulators. Here we report a notable exception an insulator, ytterbium dodecaboride (YbB12). Despite much larger than that resistivity YbB12 exhibits profound oscillations. unconventional oscillation shown to arise from insulating bulk, yet temperature dependence their amplitude...
Decoding arbitrary polarization information from an optical field has triggered unprecedented endeavors in imaging, remote sensing, and processing. Therefore, developing a detection device with full on‐chip integration miniaturization holds tremendous potential for many areas of sciences. Herein, full‐Stokes polarimetry visible light based on all‐dielectric metasurface is proposed. By combining both geometric phase propagation modulation, the to provide two uncorrelated profiles orthogonal...

A recent focus of quantum spin liquid (QSL) studies is how disorder/randomness in a QSL candidate affects its true magnetic ground state. The ultimate question whether the survives disorder or leads to "spin-liquid-like" state, such as proposed random-singlet (RS) Since standard feature most candidates, this represents major challenge for candidates. YbMgGaO$_4$, triangular lattice antiferromagnet with effective spin-1/2 Yb$^{3+}$ ions, an ideal system address question, since it shows no...

Large language models (LLMs) have established great success in the general domain of natural processing. Their emerging task generalization and free-form dialogue capabilities can greatly help to design Chemical General Intelligence (CGI) assist real-world research chemistry. However, existence specialized knowledge field chemistry, such as highly informative SMILES notation, hinders performance general-domain LLMs To this end, we develop ChemDFM, first LLM towards CGI. ChemDFM-13B is...
