Statistical mechanics of coil-hairpin transition in a single stranded DNA oligomer
Sanjay Kumar, Debaprasad Giri, Yashwant Singh
A model of self-avoiding walk with suitable constraints on self-attraction is developed to describe the conformational behavior of a short RNA or a single stranded DNA molecule tha…
Linear and branched polymers on fractals
Deepak Dhar, Yashwant Singh
This is a pedagogical review of the subject of linear polymers on deterministic finitely ramified fractals. For these, one can determine the critical properties exactly by real-spa…
Force-induced desorption of a linear polymer chain adsorbed on an attractive surface
P. K. Mishra, Sanjay Kumar, Yashwant Singh
We consider a model of self-avoiding walk on a lattice with on-site repulsion and an attraction for every vertex of the walk visited on the surface to study force-induced desorptio…
Freezing Transitions in the fluid of long elongated molecules
Pankaj Mishra, Jokhan Ram, Yashwant Singh
We have used the density-functional theory to locate the freezing transitions and calculate the values of freezing parameters for a system of long elongated molecules which interac…
Adsorbed states of a long - flexible polymer chain
Yashwant Singh, Debaprasad Giri, Sanjay Kumar
A phase diagram for a surface-interacting long flexible polymer chain in a two-dimensional poor solvent where the possibility of collapse exists is determined using exact enumerati…
