Secret sharing is a promising technology for information encryption by splitting the secret into different shares. However, traditional scheme suffers from leakage in decryption process since amount of available channels limited. Herein, we propose and demonstrate an optical framework based on multi-dimensional multiplexing liquid crystal (LC) holograms. The LC holograms are used as spatially separated shares to carry images. polarization incident light distance between served keys, which...
Light has played a crucial role in the age of information technology and facilitated soaring development optics. The ever-increasing demand for high-capacity optical devices prompted use physically orthogonal dimensions light multiplexing. Recent advances nanotechnology, mainly stemming from functionalized nanomaterials powerful nanofabrication tools, have propelled fusion multiplexing nanophotonics (the study at nanoscale its interactions with nanostructures) by enabling ultrahigh-capacity...
Beyond orbital angular momentum of Laguerre-Gaussian (LG) modes, the radial index can also be exploited as information channel in free-space optical (FSO) communication to extend capacity, resulting LG- shift keying (LG-SK) FSO communications. However, recognition is critical and tough when superposed high-order LG modes are disturbed by atmospheric turbulences (ATs). In this paper, convolutional neural network (CNN) utilized recognize both azimuthal modes. We experimentally demonstrate...
We report on the fabrication and electrical characterization of an InAs double-nanowire (NW) device consisting two closely placed parallel NWs coupled to a common superconducting electrode one side individual normal metal leads other. In this new type we detect Cooper-pair splitting (CPS) with sizeable efficiency correlated currents in both NWs. contrast earlier experiments, where CPS was realized single NW, demonstrating intrawire electron pairing mediated by superconductor (SC), our...
The two odd-even fluorine isotopes $^{27,29}\mathrm{F}$ were studied via in-beam $\ensuremath{\gamma}$-ray spectroscopy at the RIKEN Radioactive Isotope Beam Factory. A secondary beam of $^{30}\mathrm{Ne}$ was used to induce one-proton and one-proton--two-neutron removal reactions on carbon polyethylene targets midtarget energies 228 MeV/$u$. Excited states observed 915(12) keV for $^{27}\mathrm{F}$ 1080(18) $^{29}\mathrm{F}$. Both assigned a $1/{2}_{1}^{+}$ spin parity. low transition...
Abstract Angular momentum of light can be divided into spin angular and orbital (OAM). Due to the theoretically unlimited orthogonal states, physical dimension OAM provides a potential solution boost information capacity. The multiplexing modulation techniques have been implemented meet continuous growth bandwidth requirements, resulting in concept optical communication. However, performances traditional detection degrade seriously practical application communications. Thanks powerful data...
Density functional theory and its time-dependent extension are employed to investigate the intermolecular hydrogen-bonding- (Inter-HB-) induced fluorescence enhancement of benzaldehydes. The quenching mechanism benzaldehydes in chloroform is attributed low energy gap between lowest ππ* nπ* states at Franck–Condon (FC) point conical interaction states. Inter-HB aldehyde group methanol can considerably increase FC point, this type hydrogen bond strengthened excited state, thereby precluding...
The absolute structure of the 3D MOF anhydrous zinc (II) tartrate with space group I222 has been determined for both [Zn(L-TAR)] and [Zn(D-TAR)] by electron diffraction using crystals sub-micron dimensions. Dynamical refinement gives a strong difference in R factors correct inverted structures. These MOFs may be prepared phase pure from mild hydrothermal conditions. Powder X-ray indicates that isostructural or pseudo-isostructural phases can similarly several other M2+ = Mg, Mn, Co, Ni Cu....
Using a genetic algorithm incorporated with density functional theory, we explore the ground state structures of protonated water clusters H+(H2O)n n = 10–17. Then re-optimize isomers at B97-D/aug-cc-pVDZ level theory. The extra proton connects H2O molecule to form H3O+ ion in all H+(H2O)10-17 clusters. lowest-energy adopt monocage 10–16 and core-shell structure 17 based on MP2/aug-cc-pVTZ//B97-D/aug-cc-pVDZ+ZPE single-point-energy calculation. second-order vibrational perturbation further...
Isotopes are ideal substances for studying the intermolecular interactions in clathrates by replacing atoms without destroying geometry structure. When methane (CH4) spatially homogeneous hydrate was replaced with deuterated (CD4), it showed a previously unrecognized strong anharmonic effect, identified Raman peak located at 1952.78 cm–1. This assigned to coupled overtone of C–D 512 and 51262 cages on basis density functional theory. coupling vibration confirmed be present also around...
Methane hydrate is not only the predominant natural deposits of permafrost and continental margins Earth but also dominant methane-containing phase in nebula major moons gas giants. Depending on surrounding environment (mainly pressure), seven methane phases have been discovered by experiment or predicted computer simulation, such as clathrate hydrates I, II, H, K, filled-ice III, IV, V. Using extensive Monte Carlo packing algorithm density functional theory optimization, here we predict a...
Clathrate hydrates of natural gases are important backup energy sources. It is thus great significance to explore the nucleation process hydrates. Hydrate clusters building blocks crystalline and represent initial stage hydrate nucleation. Using dispersion-corrected density functional theory (DFT-D) combined with machine learning, herein, we systematically investigate evolution stabilities nuclear magnetic resonance (NMR) chemical shifts amorphous precursors from monocage CH4(H2O)n (n =...
