The chain sucker: translocation dynamics of a polymer chain into a long narrow channel driven by longitudinal flow

open access: yes, 2011
Using analytical techniques and Langevin dynamics simulations, we investigate the dynamics of polymer translocation into a narrow channel of width $R$ embedded in two dimensions, driven by a force proportional to the number of monomers in the channel ...

Optimal control theory based design of elasto-magnetic metamaterial [PDF]

open access: yes, 2017
A method to design a new type of metamaterial is presented. A two-step strategy to define an optimal long-range force distribution embedded in an elastic support to control wave propagation is considered. The first step uses a linear quadratic regulator

The establishment of the normal contact force model for a one‐dimensional sphere chain subjected to impact load

open access: yesInternational Journal of Mechanical System Dynamics, 2022
The normal contact force determines the behavior of a particle system. To investigate the normal contact force in a one‐dimensional sphere chain subjected to impact load, by comparing the simulation results of the existing typical normal contact force ...

Variations of the Lifshitz-van der Waals force between metals immersed in liquids

open access: yes, 2010
We present a theoretical calculation of the Lifshitz-van der Waals force between two metallic slabs embedded in a fluid, taking into account the change of the Drude parameters of the metals when in contact with liquids of different index of refraction ...

Fluctuation-induced forces between inclusions in a fluid membrane under tension

open access: yes, 2011
We discuss the fluctuation-induced force, a finite-temperature analog of the Casimir force, between two inclusions embedded in a fluid membrane under tension.
