Molecular hydrodynamics of the moving contact line in two-phase immiscible flows
Tiezheng Qian, Xiao-Ping Wang, Ping Sheng
The ``no-slip'' boundary condition, i.e., zero fluid velocity relative to the solid at the fluid-solid interface, has been very successful in describing many macroscopic flows. A p…
Numerical study of metastability due to tunneling: The quantum string method
Tiezheng Qian, Weiqing Ren, Jing Shi +2
We generalize the string method, originally designed for the study of thermally activated rare events, to the calculation of quantum tunneling rates. This generalization is based o…
Current Dissipation in Thin Superconducting Wires: Accurate Numerical Evaluation Using the String Method
Tiezheng Qian, Weiqing Ren, Ping Sheng
Current dissipation in thin superconducting wires is numerically evaluated by using the string method, within the framework of time-dependent Ginzburg-Landau equation with a Langev…
Hydrodynamic slip boundary condition at chemically patterned surfaces: A continuum deduction from molecular dynamics
Tiezheng Qian, Xiao-Ping Wang, Ping Sheng
We investigate the slip boundary condition for single-phase flow past a chemically patterned surface. Molecular dynamics (MD) simulations show that modulation of fluid-solid intera…
