Effects of random fields on the dynamics of the one-dimensional quantum XXZ model
Yin-Yang Shen, Xiao-Juan Yuan, Xiang-Mu Kong
The dynamics of the one-dimensional spin-1/2 quantum XXZ model with random fields is investigated by the recurrence relations method. When the fields satisfy the bimodal distributi…

Combined Influence of Off-diagonal System Tensors and Potential Valley Returning of the Optimal Path
Chun-Yang Wang
The two-dimensional barrier passage is studied in the framework of Langevin statistical reactive dynamics. The optimal incident angle for a particle diffusing in the dissipative no…
