We investigate the motion of two overlapping polymers confined in a 2D box. A statistical model is constructed using blob-free-energy arguments. We find spontaneous segregation under the condition L > R∥, and mixing under L < R∥, where L is the length of the box and R∥ is the polymer extension in an infinite slit. The segregation time (τ) is determined by solving a mean first-passage time problem and by performing Monte Carlo simulations. Both show a minimum in τ as a function of L. Although… 
Segregation of polymers under cylindrical confinement: effects of polymer topology and crowding.
Monte Carlo computer simulations are used to study the segregation behaviour of two polymers under cylindrical confinement and the conformational free energy, F, of the polymers was measured as a function of the centre-of-mass separation distance, λ, to identify discrepancies between the predicted and measured values of scaling exponents.
Polymer segregation under confinement: free energy calculations and segregation dynamics simulations.
The free energy of the system, F, is measured as a function of the distance between the centers of mass of the polymers, λ, and the effects on the free energy functions of varying the channel diameter D and length L, as well as the polymer length N and bending rigidity κ are examined.
Equilibrium organization, conformation, and dynamics of two polymers under box-like confinement.
Brownian dynamics and Monte Carlo simulations are used to study the conformation, organization and dynamics of two polymer chains confined to a single box-like cavity and the static and dynamical behaviour differs significantly from that previously observed for confinement of two polymers to a narrow channel.
Entropic Segregation of Ring Polymers in Cylindrical Confinement
Entropic forces tend to demix polymers in confinement, which has been argued to at least facilitate DNA segregation in cylindrical bacteria. Ring polymers as found in modern bacteria such as

A segregation process of two ring polyions in the confined environment, represented by a tight nanopore, has been investigated by means of the nonequilibrium Monte Carlo method on the lattice.
Segregation of semiflexible macromolecules in nanochannel.
Investigation of segregation of polymer coils in open channel was extended relative to previous studies and results indicate a stronger segregation tendency of flexible chains in channel relative to semiflexible chains both in its extent and dynamics.
Induction of entropic segregation: the first step is the hardest.
It is demonstrated that the timescale for this induction phase is exponentially growing in the chain length, while the actual segregation time scales only quadratically in theChain length, and makes entropic segregation much less efficient than previously thought.
Ejection dynamics of semiflexible polymers out of a nanochannel
Using theoretical analysis and three-dimensional Langevin dynamics simulations, we investigate the influence of chain rigidity on the ejection dynamics of polymers from a nanochannel. We find that
Free Energy of a Folded Polymer under Cylindrical Confinement
Monte Carlo computer simulations are used to study the conformational free energy of a folded polymer confined to a long cylindrical tube. The polymer is modeled as a hard-sphere chain. Its


Unexpected relaxation dynamics of a self-avoiding polymer in cylindrical confinement.
Simulation of the relaxation dynamics of a self-avoiding polymer confined inside a cylindrical pore shows that the previous scaling prediction is only asymptotically valid in the limit N"D(53)"1, which is currently inaccessible to computer simulations and, more interestingly, is also difficult to reach in experiments.

It is demonstrated that the assumption of equilibrium must break down for sufficiently long polymers (more easily when forced), and lower bounds for the translocation time by comparison to unimpeded motion of the polymer are provided.
Polymer Chains in Confined Spaces and Flow-Injection Problems: Some Remarks
We revisit the classical problem of the behavior of an isolated linear polymer chain in confined spaces, introducing the distinction between two different confinement regimes (the weak and the strong
Ejection dynamics of a ring polymer out of a nanochannel
The ejection dynamics of a ring polymer out of a cylindrical nanochannel is investigated using both theoretical analysis and three dimensional Langevin dynamics simulations, which can help to understand many biological processes, such as bacterial chromosome segregation.

We report molecular dynamics simulations of the segregation of two overlapping chains in cylindrical confinement. We find that the entropic repulsion between chains can be sufficiently strong to
Polymer translocation through a cylindrical channel.
The translocation process of a Gaussian chain without excluded volume and hydrodynamic interactions is studied using exact formulas of confinement free energy under this formalism of polymer translocation through a cylindrical channel of finite diameter and length between two spherical compartments.

Through computer simulations, it is presented evidence that, under strong confinement conditions, topologically distinct domains of a polymer complex effectively repel each other to maximize their conformational entropy, suggesting that duplicated circular chromosomes could partition spontaneously.

The distribution of first passage times in the limit of long times is obtained and it is shown that the prefactor in the power relation for this distribution is simply the expression for the mean first passage time in classical diffusion.

It turns out that, while the chemical potential differences induce pronounced effects on translocation due to the long-chain nature of the polymer, the ratchets suppress this effect and chain flexibility.
