A simple model of DNA based on two interacting polymers has been used to study the
unzipping of a double stranded DNA subjected to a periodic force. We propose a dynamical …

We study by using Monte Carlo simulations the hysteresis in unzipping and rezipping of a
double stranded DNA (dsDNA) by pulling its strands in opposite directions in the fixed force …

Using Langevin dynamics simulations, we study a simple model of interacting-polymer
under a periodic force. The extension curves strongly depend on the magnitude of the …

We investigate, by numerical simulation, the path probability of non dissipative mechanical
systems undergoing stochastic motion. The aim is to search for the relationship between this …

The force induced unzipping transition of a double stranded DNA is considered from a
purely thermodynamic point of view. This analysis provides us with a set of relations that can …

The unzipping of a double stranded DNA whose ends are subjected to a time dependent
periodic force with frequency ω and amplitude G is studied using Monte Carlo simulations …

A three-stranded DNA with short range base pairings only is known to exhibit a classical
analog of the quantum Efimov effect, viz., a three-chain bound state at the two-chain melting …

We consider in this paper, a few important issues in non-equilibrium work fluctuations and
their relations to equilibrium free energies. First we show that the Jarzynski identity can be …

The present thesis is devoted to the study of path probability of random motion on the basis
of an extension of Hamiltonian/Lagrangian mechanics to stochastic dynamics. The path …

DNA is a bio-molecule found, without any known exception, in every cellular lifeform. In
biology the fundamental phase of reproduction is the cell-division. During cell division the …
