Holographic superfluid ring with a weak link

引用

Science China(Physics,Mechanics & Astronomy) 2024年第11期67卷 29-38页

作者： zhi-hong Li Huai-Fan Li Department of Physics Shanxi Datong UniversityDatong 037009China Institute of Theoretical Physics Shanxi Datong UniversityDatong 037009China

We explore the generation of topological defects in the course of a dynamical phase transition in a ring with a weak link, i.e., a SSS Josephson junction, from the AdS/CFT correspondence. By setting different parameters of the junction(width, steepness,depth) and the final temperature of the quench, the configurations of the charge density and condensate of the order parameters of the dual field theory are presented. Meanwhile, we observe that in the final equilibrium state, variations in parameters of the junctions only affect the configurations of the charge density and condensate of the order parameters, without altering their values outside the junction. However, variations in the final temperature will directly affect the values of the charge density and condensate of the order parameters outside of the junction. Moreover, in the final equilibrium state, we propose an analytic relation between the gauge-invariant velocity in the two superconducting states in the SSS Josephson junction, which agrees well with the numerical results.

Detection of Salmonella in Forage by Dot-ELISA

Animal Husbandry and Feed Science 2011年第5期3卷 42-44页

作者： HAN zhi-hui ZHANG hong-jian Department of Animal Medicine Qinghai University Xining 810016 China

[ Objective] To develop a dot-ELISA （ dot-enzyme linked immunosorbent assay） method for detection of Salmonella in forage. [ Method] Forage samples including 100 finished feed samples, 85 fishmeal samples and 50 protamine samples were randomly collected from a feed factory in Xining City, and Salmonella in these samples were detected by dot-ELISA. The Salmonella isolates were further identified using biochemical tests and serological tests. [Result] As detected by dot-ELISA, the positive rates of Salmonella in the finished feed, fishmeal and protamine were 38.00%, 62.35% and 60.00%, respectively. The coincidence rate between the dot-ELISA and routine identification method was 82.23%. [ Conclusion] The dot-ELISA has good specificity and sensitivity and is highly coincidental with the routine identification method. Therefore, dot-ELISA can be used for detection of Salmonella in forage.
