We perform Monte Carlo simulations on the body-centered-tetragonal helimagnet with Heisenberg spins which has the same breakdown of symmetry as the stacked triangular antiferromagnetic lattices and must belong to the same universality class. We obtain a second-order transition with similar...

Thermodynamic properties of a DNA hairpin are investigated employing non-Boltzmann Monte Carlo simulation. We model the DNA hairpin as a polymer on a two dimensional square lattice. We Consider bond fluctuation model with each bead occupying four-sites. The system exhibits a transition from a...

Monte Carlo simulations for a simple model for liquid crystals in the bulk are presented. The model potential describes the anisotropy of the particles in the attractive part of the Lennard Jones-like pair interaction. Isotherms were calculated with constant-volume and constant-pressure...

This work describes a novel mechanism for phase transitions during desorption, involving the formation of lattice size dependent intermediate states when there is enough adsorbate mobility. Monte Carlo simulations are performed to analyze the mechanism of the thermal desorption for adsorbed...

X-Chromosome inactivation is the process whereby one of the two X-chromosomes in female cells is silenced to prevent the cell producing too much of any X-linked proteins and RNA. The proposed blocking-factor mechanism of X-inactivation is not well understood and hence is the subject of much...

Using Wolff's single-cluster Monte-Carlo update algorithm, the three-dimensional O(6)-Heisenberg model on a simple cubic lattice is simulated. With the help of finite size scaling we compute the critical exponents ν, β, γ and η. Our results agree with the field-theory predictions but not so...
