Using Langevin simulations, we numerically study the dynamics of driven 2D colloids subject to the randomly distributed point like pinning centers. With increasing the strength of pinning centers, we find a crossover from elastic to plastic depinnings, where a substantial increase in the depinning force is observed, analogous to the peak effect in superconductors. We find for the first time, when the plastic flow occurs, the average pinning force that colloids feel in the linear flow region shows a peak across...

Using Langevin simulations, we numerically study the dynamics of driven 2D colloids subject to the randomly distributed point like pinning centers. With increasing the strength of pinning centers, we find a crossover from elastic to plastic depinnings, where a substantial increase in the depinning force is observed, analogous to the peak effect in superconductors. We find for the first time, when the plastic flow occurs, the average pinning force that colloids feel in the linear flow region shows a peak across the colloid glass to colloid liquid transition. The peak is accompanied by a clear crossing of the velocity versus driving force curves.

Using Langevin molecular dynamics method, we have studied the voltage noise spectrum generated by current-driven vortices as a function of the magnetic field and current. It is found that the broad band noise (BBN) at low frequencies decreases with increasing magnetic field, it decreases at the magnetic field near the vortex dynamic transition field F-P, and the Lorentze narrow band noise (NBN) at high frequencies appears. As the magnetic field increases near the melting field F-m, the NBN peak goes up and shifts...

Using Langevin molecular dynamics method, we have studied the voltage noise spectrum generated by current-driven vortices as a function of the magnetic field and current. It is found that the broad band noise (BBN) at low frequencies decreases with increasing magnetic field, it decreases at the magnetic field near the vortex dynamic transition field F-P, and the Lorentze narrow band noise (NBN) at high frequencies appears. As the magnetic field increases near the melting field F-m, the NBN peak goes up and shifts towards higher frequencies. In the elastic motion region of vortices with strong driving currents, NBN exhibits the washboard-like shape. This behavior arises from the periodic modulation of the translational velocity of vortices, suggesting that there is a Bragg glass phase with the translation order in the vortex lattices of the layered superconductors.

Langevin分子动力学方法模拟磁通运动的纵向电压噪声谱随磁场和电流的变化.计算结果表明,外加磁场增大到磁通运动动力学相变场FP,电压噪声谱中低频宽带噪声减小而出现洛伦兹形高频窄带噪声.外加磁场增大到熔化场Fm附近,高频窄带噪声峰值增高,峰值对应频率增大.在外加电流增强到磁通弹性运动区域,高频窄带噪声频谱呈现搓衣板形式.搓衣板高频窄带噪声产生于磁通平移速度的周期性调制,它表明层状超导体中运动的磁通格子存在有平移序的BG相.

The conformational transitions of protein in a confined space were abstracted to represent the physical nature of the stabilization,destabilization,folding and unfolding of protein molecule in solution.A Gō-like model was applied to investigate the conformation distribution and the conformational transition of an all β-sheet protein in spherical cages of different sizes and surface hydrophobicity using Langevin molecular dynamics.It was found that a cage of moderate size and hydrophobicity significantly enhanced protein collapsed whereas a hydrophilic cage with appropriate size stabilized the collapsed conformation.The effect of the surface property on the structural changes of protein decreases in response to the increase in the cage size.The simulation agrees well as experimental results reported elsewhere and has a high potential in the study of protein folding/refolding and stabilization in solution.

将蛋白质的稳定和失活、折叠和去折叠等现象概括为蛋白质分子在溶液中的构象变化问题。采用非晶格模型和Langevin分子动力学方法研究了无限稀释溶液及不同尺度和不同表面亲/疏水性球形限制性空间内β模型蛋白的构象分布及其转换特性。模拟结果显示:尺寸适度的疏水性空间有利于蛋白质结构发生缩塌,而亲水性空间有利于缩塌态蛋白质结构的稳定,且表面亲/疏水性的影响作用随着空间半径的增大而减弱。计算结果与实验报道一致,为研究蛋白质分子在溶液中的折叠和稳定化提供了理论工具。
