Polymer Chain Collapse in Supercritical Fluids
C. Ortiz-Estrada, G. Luna-Barcenas, G. Ramirez-Santiago +2
My means of extensive Monte Carlo simulations the mean radius of gyration and the end-to-end distance are calculated for a single chain in a solvent over a broad range of volume fr…

A generalization of the spherical model: Reentrant phase transition in the spin one ferromagnet
Sergey E. Savelev, G. Ramirez-Santiago
By mapping the hamiltonian of the spin one ferromagnet onto that of the classical spherical model we investigate the possible phase transitions and the phase diagram of the spin on…

Scaling of the Structure Factor in Fractal Aggregation of Colloids: Computer Simulations
Agustin E. Gonzalez, Guillermo Ramirez-Santiago
In the volume fraction range (0.005,0.08), we have obtained the temporal evolution of the structure factor , in extensive numerical simulations of both diffusion-limited and…
