Study on energy extraction assisted with quantum correlated coherence in bath
Hai Li, Jian Zou, Bin Shao, Yu Chen, and Zhen Hua
Based on a hybrid model of a single-mode microcavity system plus an ensemble of two-level atoms (TLAs), we investigate the effect of quantum correlated coherence (QCC) [Tan K C, et al. 2016 Phys. Rev. A 94, 022329] of bath on the dynamic behaviors of system. The dynamic equations of system for a general bath with QCC h

Properties and applications of one dimensional quasiperiodic lattices
Yu-Cheng Wang, Xiong-Jun Liu, and Shu Chen
Quasiperiodic lattices have been widely studied in cold atoms, which make one study extended-Anderson localization transition in one-dimensional (1D) or two-dimensional (2D) systems. In 2008, Inguscio's group prepared one-dimensional quasiperiodic lattice in cold atomic system and observed Anderson localization, wh

Review of one-dimensional few-body systems in ultracold atomic physics
Yan-Xia Liu, and Yun-Bo Zhang
We review some recent theoretical and experimental developments of one-dimensional few-body problems in ultracold atomic system. The experiments have so far realized the deterministic loading of few atoms in the ground state of a potential well, the observation of tunneling dynamics out of the metastable trap controlle

X-ray transmission characteristics and potential communication application in plasma region
Yao Li, Tong Su, Fan Lei, Neng Xu, Li-Zhi Sheng, and Bao-Sheng Zhao
When a supersonic spacecraft enters into the atmosphere of earth, part of the spacecraft's kinetic energy changes into thermal energy, thus causing the air surrounding the craft to be heated and compressed. As a result, the temperature near the surface may reach several thousands of kelvins, which leads the surface

Optimal estimation retrieval for directional polarimetric camera onboard Chinese Gaofen-5 satellite: an analysis on multi-angle dependence and a posteriori error
Feng-Xun Zheng, Wei-Zhen Hou, and Zheng-Qiang Li
Data from the directional polarimetric camera (DPC) instrument onboard Chinese Gaofen-5 satellite dedicated to aerosol monitoring have been available recently. By measuring the spectral, angular and polarization properties of the radiance at the top of atmosphere (TOA), a DPC provides the aerosol optical depths (AODs)

Helium behavior of tungsten investigated by helium ion microscope
Yu-Tian Ma, Jun-Biao Liu, Li Han, Li-Feng Tian, Xue-Cong Wang, Xiang-Min Meng, Shan-Qu Xiao, and Bo Wang
Nuclear fusion energy is a clean and safe energy resource with huge potential. Tungsten is the primary candidate for plasma facing materials (PFMs) in future nuclear reactors because of its high melting point, high thermal conductivity and high resistance to sputtering and erosion. However, the interaction between tung

Theoretical investigation on hyperfine structure and isotope shift for 5d106s 2S1/2→5d96s2 2D5/2 clock transition in Hg+
Xiang Zhang, Ben-Quan Lu, Ji-Guang Li, and Hong-Xin Zou
The Dirac-Hartree-Fock approximation is adopted to calculate the mass shift and the field shift for the 5d106s 2S1/2→5d96s2 2D5/2 clock transition in Hg+. It is found that the field shift is much larger than the mass shift so that the latter can be neglected in the isotope shift. In addition, we estimate that the isoto

Laser cooling and trapping of polar molecules
Tao Chen, and Bo Yan
Different from atoms, molecules have unique properties, and play an important role in the research of atomic, molecular and optical physics. Cold molecules have important applications in science and have been studied for more than 20 years. But traditional methods, such as the Stark decelerator, have hit a bottleneck:

Enhanced stimulated Raman scattering by suppressing stimulated Brillouin scattering in liquid water
Jiu-Lin Shi, Jin Xu, Ning-Ning Luo, Qing Wang, Yu-Bao Zhang, Wei-Wei Zhang, and Xing-Dao He
Stimulated Brillouin scattering (SBS) and stimulated Raman scattering (SRS) are two kinds of emblematic inelastic scattering processes resulting from the interaction of high-intensity laser with matter. Generally, competition between SBS and SRS is a common phenomenon in many substances. In liquid or high-pressure gas,

Simplification of roughness bottom backscattering model at small grazing angle in shallow-water
Qian-Nan Hou, and Jin-Rong Wu
Bottom backscattering due to roughness seafloor is the main source of shallow water reverberation, especially in the waveguide with downward reflection profile or a calm sea-surface. Empirical backscattering models with a simple form has an important limitation to analyzing other characteristics of reverberation except

First-principles study of structure, electronic structure and thermoelectric properties for Co2-based Heusler alloys Co2FeAl1–xSix (x = 0.25, x = 0.5, x = 0.75)
Yan-Min Yang, Jia Li, Hong-Ran Ma, Guang Yang, Xiu-Juan Mao, and Cong-Cong Li
In the recent decades, the half-metallic materials have become a research hotspot because of their unique electronic structure. The 100% spin polarization at the Fermi level makes them widely used in spintronic devices. The Co-based Heusler alloys belong to an important class of magnetic material, and Co2FeAl and Co2Fe

Conjugated polymers have been widely used in optical sensors, light-emitting diodes and solar cells, due to their attractive optical and semiconducting properties. It is widely accepted that the optical and electrical properties of conjugated polymer molecules depend on the conjugated segments, i.e., chromophores in co

Temperature dependence of single-event transient response in devices with selective-buried-oxide structure
Zhan-Zhan Gao, Peng-Fei Hou, Hong-Xia Guo, Bo Li, Hong-Jia Song, Jin-Bin Wang, and Xiang-Li Zhong
The silicon-on-insulator (SOI) device has been found to possess low leakage current and high operation speed due to reduced internal capacitances. The sensitive volume for charge collection in SOI device is smaller than that in bulk-silicon device, which improves the ability of SOI devices to resist single-event effect
