Tunable devices constructed by ferroelectric thin flms are often desired to possess a low dielectric loss while maintainging a high dielectric tunability over a broad operating temperature range in applications,for example,resonators,filters,or phase ***,it is dificult to simultaneously achieve these characteristics by traditional strategies,such as doping and strain ***,we demonstrate that the dielectric tunability of the sol-gel-prepared Pb(Sc_(1/2.Nb_(1/2.)_(0.9)(Mg_(1/3)Nb_(2.3))_(0.O3)(PSNMN)thin film can be almost doubled from~47%to~80.0%(at 10kHz)at a low electric field(~530kV/cm),and the dielectric loss can be sharply reduced by more than an order of magnitude,from~0.50 to~0.037(at 1 kHz)when the thin flm was annealed in air at 650℃ for 15h under the help of an atmosphere-compensating-block(ACB)made from the proto-PSNMN ***,the PSNMN thin flm annealed with ACB also exhibited an extremely high thermally-stable dielectric tunability in an ultrabroad temperature range(>130 K),which could be attributed to the Maxwell-Wagner(MW)effect generated by the interface between the PSNMN disordered matrix and the B-site nanoscale-ordered structure formed during the long-term annealing *** reduced dielectric loss is mainly benefited from the reduced concentration of oxygen vacancy and the possibie MW efects,and the enhanced dielectric tunability could be ascribed to the weaker domain-pinning effect by oxygen *** breakthrough provides a new universal strategy to achieve utrahigh tunable performance in A(B'_(1/2.B"_(1/2.)O3 ferroelectric thin films with a B-site nanoscale-ordered structure,meanwhile it paves the way for ultraintergrated tunable thin-flm-devices with great phase shifter performance in practical applications.

The nature of the zero-temperature phase diagram of the spin-1/2.J_(1)-J_(2.Heisenberg model on a square lattice has been debated in the past three decades,and it remains one of the fundamental problems unsettled in the study of quantum many-body *** using the state-of-the-art tensor network method,specifically,the finite projected entangled pair state(PEPS)algorithm,to simulate the global phase diagram of the J_(1)-J_(2.Heisenberg model up to 2.×2. sites,we provide very solid evidences to show that the nature of the intermediate nonmagnetic phase is a gapless quantum spin liquid(QSL),whose spin-spin and dimer-dimer correlations both decay with a power law *** also exists a valence-bond solid(VBS)phase in a very narrow region 0.56■J_(2./J_(1)≤0.61 before the system enters the well known collinear antiferromagnetic *** stress that we make the first detailed comparison between the results of PEPS and the well-established density matrix renormalization group(DMRG)method through one-to-one direct benchmark for small system sizes,and thus give rise to a very solid PEPS calculation beyond *** numerical evidences explicitly demonstrate the huge power of PEPS for highly frustrated spin ***,an effective field theory is also proposed to understand the physical nature of the discovered gapless QSL and its relation to deconfined quantum critical point(DQCP).

A new architecture, naked-eye ghost imaging via photoelectric feedback, is developed that avoids computer algorithm processing. Instead, the proposed scheme uses a photoelectric feedback loop to first realize the correlation(multiplication) process of the traditional ghost imaging system. Then, the vision persistence effect of the naked eye is exploited to implement the integral process and to generate negative images. Two kinds of feedback circuits, the digital circuit and the analog circuit, are presented that can achieve a feedback operation. Based on this design, high-contrast real-time imaging of moving objects is obtained via a special pattern-scanning architecture on a low-speed light-modulation mask.

The Panda X-4T experiment, a 4-ton scale dark matter direct detection experiment, is being planned at the China Jinping Underground Laboratory. In this paper we present a simulation study of the expected background in this experiment. In a 2.8-ton fiducial mass and the signal region between 1-10 keV electron equivalent energy, the total electron recoil background is found to be 4.9 × 10^(-5) kg^(-1) d^(-1) keV^(-1). The nuclear recoil background in the same region is 2.8 × 10^(-7) kg^(-1) d^(-1) keV^(-1). With an exposure of 5.6 ton-years, the sensitivity of Panda X-4 T could reach a minimum spin-independent dark matter-nucleon cross section of 6 × 10^(-48) cm^2.at a dark matter mass of 40 Ge V/c^2.

The Large sky Area Multi-Object Fiber Spectroscopic Telescope（LAMOST） general survey is a spectroscopic survey that will eventually cover approximately half of the celestial sphere and collect 10 million spectra of stars, galaxies and QSOs. Objects in both the pilot survey and the first year regular survey are included in the LAMOST DR1. The pilot survey started in October 2.11 and ended in June 2.12. and the data have been released to the public as the LAMOST Pilot Data Release in August 2.12. The regular survey started in September 2.12. and completed its first year of operation in June 2.13. The LAMOST DR1 includes a total of 12.2.plates containing 2.955 336 spectra, of which 1 790 879 spectra have observed signalto-noise ratio（SNR） ≥ 10. All data with SNR ≥ 2.are formally released as LAMOST DR1 under the LAMOST data policy. This data release contains a total of 2.2.4 696 spectra, of which 1 944 32. are stellar spectra, 12.082.are galaxy spectra and 5017 are quasars. The DR1 not only includes spectra, but also three stellar catalogs with measured parameters： late A,FGK-type stars with high quality spectra（1 061 918 entries）, A-type stars（100 073 entries）, and M-type stars（12. 52. entries）. This paper introduces the survey design, the observational and instrumental limitations, data reduction and analysis, and some caveats. A description of the FITS structure of spectral files and parameter catalogs is also provided.
