Dynamic scaling theory of the forced translocation of a semi-flexible polymer through a nanopore
Pui-Man Lam, Yi Zhen
We present a theoretical description of the dynamics of a semi-flexible polymer being pulled through a nanopore by an external force acting at the pore. Our theory is based on the…
Worm-Like-Chain Model of Forced Desorption of a Polymer Adsorbed on an Attractive Wall
Pui-Man Lam, Yi Zhen
Forced desorption of a semiflexible polymer chain on a solid substrate is theoretically investigated. The pulling force versus displacement is studied for different adsorption ener…
Force Induced Unzipping of DNA with Long Range Correlated Noise
Pui-Man Lam, Yi Zhen
We derive and solve a Fokker-Planck equation for the stationary distribution of the free energy, in a model of unzipping of double-stranded DNA under external force. The autocorrel…
Discrete Persistent Chain Model for Protein Binding on DNA
Pui-Man Lam, Yi Zhen
We describe and solve a discrete persistent chain model of protein binding on DNA, involving an extra sigma_i s at a site i of the DNA. This variable takes the value 1 or 0 dependi…
Stretching self-interacting, partially directed, flexible and semi-flexible polymers by an external force
Pui-Man Lam, Yi Zhen
We study the model of a partially directed flexible or semi-flexible homopolymer on a square lattice, subject to an externally applied force, in a direction either parallel to, or…
Adsorption of Externally Stretched Two-Dimensional Flexible and Semi-flexible Polymers near an Attractive Wall
Pui-Man Lam, Yi Zhen, Haijun Zhou +1
We study analytically a model of a two dimensional, partially directed, flexible or semiflexible polymer, attached to an attractive wall which is perpendicular to the preferred dir…
