Driven translocation of a semi-flexible polymer through a nanopore
Jalal Sarabadani, Timo Ikonen, Harri Mökkönen +3
We study the driven translocation of a semi-flexible polymer through a nanopore by means of a modified version of the iso-flux tension propagation theory (IFTP), and extensive mole…
Theory of polymer translocation through a flickering nanopore under an alternating driving force
Jalal Sarabadani, Timo Ikonen, Tapio Ala-Nissila
We develop a theory for polymer translocation driven by a time-dependent force through an oscillating nanopore. To this end, we extend the iso-flux tension propagation theory (IFTP…
Polymer escape from a confining potential
Harri Mökkönen, Timo Ikonen, Tapio Ala-Nissila +1
The rate of escape of polymers from a two-dimensionally confining potential well has been evaluated using self-avoiding as well as ideal chain representations of varying length, up…
Transition State Theory Approach to Polymer Escape from a One Dimensional Potential Well
Harri Mökkönen, Timo Ikonen, Tapio Ala-Nissila +1
The rate of escape of an ideal bead-spring polymer in a symmetric double-well potential is calculated using transition state theory (TST) and the results compared with direct dynam…
Iso-Flux Tension Propagation Theory of Driven Polymer Translocation: The Role of Initial Configurations
Jalal Sarabadani, Timo Ikonen, Tapio Ala-Nissila
We investigate the dynamics of pore-driven polymer translocation by theoretical analysis and molecular dynamics (MD) simulations. Using the tension propagation theory within the co…
Polymer Escape from a Metastable Kramers potential: Path Integral Hyperdynamics Study
Jaeoh Shin, Timo Ikonen, Mahendra D. Khandkar +2
We study the dynamics of flexible, semiflexible, and self-avoiding polymer chains moving under a Kramers metastable potential. Due to thermal noise, the polymers, initially placed…
