Dynamic phase transition of the Blume-Capel model in an oscillating magnetic field


Author(s): Erol Vatansever and Nikolaos G. Fytas

We employ numerical simulations and finite-size scaling techniques to investigate the properties of the dynamic phase transition that is encountered in the Blume-Capel model subjected to a periodically oscillating magnetic field. We mainly focus on the study of the two-dimensional system for various...

Characterization of microscopic deformation through two-point spatial correlation functions

Insensitivity of active nematic liquid crystal dynamics to topological constraints


Author(s): Michael M. Norton, Arvind Baskaran, Achini Opathalage, Blake Langeslay, Seth Fraden, Aparna Baskaran, and Michael F. Hagan

Computer simulations are used to study the effect of confinement on the dynamics of active nematic liquid crystals. The authors find that active nematic systems, in contrast to passive systems, are rather insensitive to topological constraints. Topological charges required by container geometry are relegated to a small layer along the boundary, creating a bulklike interior for these active systems.

Theoretical analysis of the distribution of isolated particles in totally asymmetric exclusion processes: Application to mRNA translation rate estimation


Author(s): Khanh Dao Duc, Zain H. Saleem, and Yun S. Song

This paper extends the treatment of a simple stochastic transport model to account for the distribution of particles, and applies it to ribosomes involved in messenger RNA translation. This approach makes it possible to describe properties such as the average distance between particles and the number of collisions. These results can be used as support for recently developed experimental techniques like ribosome profiling.
