Cold atoms with laser-induced spin-orbit (SO) interactions provide intriguing new platforms to explore novel quantum physics beyond natural conditions of solids. Recent experiments demonstrated the one-dimensional (1D) SO coupling for boson and fermion gases. However, realization 2D interaction, a much more important task, remains very challenging. Here we propose experimentally realize, first time, topological band $^{87}$Rb degenerate gas through minimal optical Raman lattice scheme,...
Unique spindle-shaped nanoporous anatase TiO(2) mesocrystals with a single-crystal-like structure and tunable sizes were successfully fabricated on large scale through mesoscale assembly in the tetrabutyl titanate-acetic acid system without any additives under solvothermal conditions. A complex process involving slow release of soluble species from metastable solid precursors for continuous formation nascent nanocrystals, oriented aggregation tiny entrapment situ produced butyl acetate as...
Facile fabrication of well-aligned Li4Ti5O12 (LTO) nanosheet arrays grown directly on conductive Ti foil was achieved by hydrothermal growth in LiOH solution. The reaction between and led to the vertically aligned, rectangular lithium titanate oxide hydrate (H-LTO) arrays, which could be converted into LTO through topotactic transformation via thermal decomposition. An appropriate concentration essential for formation densely aligned H-LTO substrate. It proposed that kinetics-controlled...

These novel mesostructures exhibit efficient suppression reflection towards wavelengths...
A single photon source is realized with a cold atomic ensemble ($^{87}$Rb atoms). In the experiment, photons, which initially stored in an quantum memory generated by Raman scattering of laser pulse, can be emitted deterministically at time-delay control. It shown that production rate photons enhanced feedback circuit considerably while single-photon quality conserved. Thus our present well suitable for future large-scale realization communication and linear optical computation.

The rational design and controllable fabrication of electrode materials with tailored structures superior performance is highly desirable for the next-generation lithium ion batteries (LIBs). In this work, a novel three-dimensional (3D) graphite foam (GF)@SnO2 nanorod arrays (NRAs)@polyaniline (PANI) hybrid architecture was constructed via solvothermal growth followed by electrochemical deposition. Aligned SnO2 NRAs were uniformly grown on surface GF, PANI shell thickness ∼40 nm coated...
We propose a hierarchy set of minimal optical Raman lattice schemes to pave the way for experimental realization high-dimensional spin-orbit (SO) couplings ultracold atoms, including two-dimensional (2D) Dirac type, 2D Rashba and three-dimensional (3D) Weyl type. The proposed Dirac-type SO coupling exhibits precisely controllable high symmetry, which large topological phase region is predicted. generation 3D types requires that two sources laser beams have distinct frequencies factor 2...
Plasmonic CN-NiMoN heterojunctions were prepared to enhance H 2 evolution from water splitting under visible-light ( λ ≥ 420 nm). Under irradiation, the optimal heterojunction shows 5.4 times higher activity than that of g-C 3 N 4 .
CoZnS@NSC nanoparticles derived from a CoZn-MOF were synthesized by an annealing–sulfurization strategy and used as co-catalysts for g-C 3 N 4 , which effectively augmented the photocatalytic H 2 production.
In recent years, graphitic carbon nitride (g-C3N4) has attracted considerable attention because it includes earth-abundant and nitrogen elements exhibits good chemical thermal stability owing to the strong covalent interaction in its conjugated layer structure. However, bulk g-C3N4 some disadvantages of low specific surface area, poor light absorption, rapid recombination photogenerated charge carriers, insufficient active sites, which hinder practical applications. this study, we design...
