In this report we consider two weakly coupled Schrödinger equations as a reduced model of interchain energy transport in the DNA double-helix torsional model. We employ a reduction of the Yakushevich-type model that considers the torsional dynamics of the DNA as effective chains of pendula. In previous works, only small amplitude excitations and stationary dynamics were investigated, whereas we focus on the nonstationary dynamics of the double helix. We consider the system to be a model of two… 



Composite model for DNA torsion dynamics.

A "composite" version of the Y model is proposed, in which the sugar-phosphate group and the base are described by separate degrees of freedom, and shows that the existence of solitons is a generic feature of the underlying nonlinear dynamics and is to a large extent independent of the detailed modeling of DNA.

Low-Frequency Localized Oscillations of the DNA Double Strand

The results of the molecular dynamic study on the low-energy elementary linear and nonlinear excitations of DNA macromolecule obtained within the framework of the coarse-grain model of the DNA double

Theory of DNA melting based on the Peyrard-Bishop model

The DNA melting based on the Peyrard-Bishop (PB) model is systematically investigated. Our study on the eigenvalues and eigenvectors of the transfer integral equation for the original PB model points

New approach to beating phenomenon in coupled nonlinear oscillatory chains

We propose an adequate analytical approach to the description of nonlinear vibration with strong energy exchange between weakly coupled oscillators. The fundamental notion of the limiting phase

Helicoidal model for DNA opening

The ABCs of molecular dynamics simulations on B-DNA, circa 2012

A retrospective on the ABC initiative in the area of all-atom molecular dynamics simulations including explicit solvent on all tetranucleotide steps of duplex B-form DNA duplex is provided, including a detailed comparison of the ff99/parmbsc0 results with crystal and NMR structures available for d(CGCGAATTCGCG).

MD simulation of the transitions between B-DNA and A-DNA in the framework of a coarse-grained model

Transitions between the B and A forms of a short DNA double helix (12 base pairs) at different salt concentrations in an aqueous solution have been studied by the molecular dynamics method in the

Nonlinear dynamics of topological solitons in DNA.

It is shown that three types of topological solitons can occur in the DNA double chain and their interactions with the chain inhomogeneities are investigated.

The “sugar” coarse-grained DNA model

The proposed coarse-grained DNA model allows to reproduce both the B- and A- DNA forms and the transitions between them under corresponding conditions and demonstrates both the A to B and the B to A phase transitions.
