Dynamics of glass phases in the two-dimensional gauge glass model

Qing-Hu Chen, Jian-Ping Lv, Huan Liu

Large-scale simulations have been performed on the current-driven two-dimensional XY gauge glass model with resistively-shunted-junction dynamics. It is observed that the linear re…

Elastic theory for the vortex-lattice melting in iron-based high-Tc superconductors

Qing-Hu Chen, Qing-Miao Nie, Jian-Ping Lv

The vortex-lattice melting transitions in two typical iron-based high-Tc superconductor $B a (F e_{1 - x} C o_{x})_{2} A s_{2}$ (122-type) and $N d (O_{1 - x} F_{x}) F e A s$ (1111-type) for magnetic…

Phase transition in site-diluted Josephson junction arrays: A numerical study

Jian-Ping Lv, Huan Liu, Qing-Hu Chen

We numerically investigate the intriguing effects produced by random percolative disorder in two-dimensional Josephson-junction arrays. By dynamic scaling analysis, we evaluate cri…

Flux-lattice melting in LaO $_{1 - x}$ F $_{x}$ FeAs: first-principles prediction

Jian-Ping Lv, Qing-Hu Chen

We report the theoretical study of the flux-lattice melting in the novel iron-based superconductor $L a O_{0.9} F_{0.1} F e A s$ and $L a O_{0.925} F_{0.075} F e A s$ . Using the Hypernetted-Chai…

On the Origin of the Tunneling Asymmetry in the Cuprate Superconductors: a variational perspective

Hong-Yu Yang, Fan Yang, Yong-Jin Jiang +1

Through variational Monte Carlo calculation on Gutzwiller projected wave functions, we study the quasiparticle(qp) weight for adding and removing an electron from a high temperatur…
