چکیده
Lakatos et al.[Phys. Rev. E 71, 011103 (2005)] have studied a totally asymmetric exclusion process that contains periodically varying movement rates. They have presented a cluster mean-field theory for the problem. We show that their cluster mean-field theory leads to redundant equations. We present a mean-field analysis in which there is no redundant equation.

Steady-state properties of a totally asymmetric exclusion process with periodic structure.
We study the steady-state behavior of totally asymmetric simple exclusion processes (TASEPs) that contain periodically varying movement rates. In this model, particles move to the right at one of two rates: p(2) if the particle occupies one of a periodically arranged set of lattice sites; p(1) otherwise. Approximate mean field approaches are used to study the steady-state currents and bulk dens...
متن کاملTotally asymmetric exclusion processes with particles of arbitrary size
The steady-state currents and densities of a one-dimensional totally asymmetric exclusion process (TASEP) with particles that occlude an integer number (d ) of lattice sites are computed using various mean-field approximations and Monte Carlo simulations. TASEPs featuring particles of arbitrary size are relevant for modelling systems such as mRNA translation, vesicle locomotion along microtubul...

متن کاملStatistics of current-activity fluctuations in asymmetric flow with exclusion.
We consider steady-state current activity statistics for the one-dimensional totally asymmetric simple exclusion process. With the help of the known operator algebra (for general open boundary conditions), as well as general probabilistic concepts (for the periodic case), we derive and evaluate closed-form expressions for the lowest three moments of the probability distribution function. These ...
متن کاملAsymptotics for the Norm of Bethe Eigenstates in the Periodic Totally Asymmetric Exclusion Process
The normalization of Bethe eigenstates for the totally asymmetric simple exclusion process on a ring of L sites is studied, in the large L limit with finite density of particles, for all the eigenstates responsible for the relaxation to the stationary state on the KPZ time scale T ∼ L. In this regime, the normalization is found to be essentially equal to the exponential of the action of a scala...
