In this paper we consider a model of accelerated dynamics with the rules modified from those of the recently proposed [Dong et al., Phys. Rev. Lett. 109, 130602 (2012)] accelerated exclusion process (AEP) such that particle-vacancy symmetry is restored to facilitate a mapping to a solid-on-solid growth model in 1 + 1 dimensions. In addition to kicking a particle ahead of the moving particle, as in the AEP, in our model another particle from behind is drawn, provided it is within the “distance of interaction” denoted by max. We call our model the doubly accelerated exclusion process (DAEP). We observe accelerated transport and interface growth and widening of the cluster size distribution for cluster sizes above max, when compared with the ordinary totally asymmetric exclusion process (TASEP). We also characterize the difference between the TASEP, AEP, and DAEP by computing a “staggered” order parameter, which reveals the local order in the steady state. This order in part explains the behavior of the particle current as a function of density. The differences of the steady states are also reflected by the behavior of the temporal and spatial correlation functions in the interface picture. ...

Numerical studies of transport in complex many-particle systems far from equilibrium Kauttonen, Janne (University of Jyväskylä, 2012)In this Thesis, transport in complex nonequilibrium many-particle systems is studied using numerical master equation approach and Monte Carlo simulations. We focus on the transport of the center-of-mass of deformable ...
Many-particle theory for time-dependent quantum transport in nanostructures Myöhänen, Petri (University of Jyväskylä, 2012)During the recent decades, molecular electronics has established its place as one of the promising fields in the nanoscience. The possibility to manufacture and control molecular junctions where single molecules are ...
Modeling of intracellular transport in realistic cell geometries Aho, Vesa (University of Jyväskylä, 2018)The transport of molecules inside cells is a complex process, the characterization of which is important to gain full understanding of cellular processes. Understanding of intracellular transport is also important for ...
Coupled conditional backward sampling particle filter Lee, Anthony; Singh, Sumeetpal S.; Vihola, Matti (Institute of Mathematical Statistics, 2020)The conditional particle filter (CPF) is a promising algorithm for general hidden Markov model smoothing. Empirical evidence suggests that the variant of CPF with backward sampling (CBPF) performs well even with long time ...
Finite-size effects in dynamics of zero-range processes Juntunen, Janne; Pulkkinen, Otto; Merikoski, Juha (2010)The finite-size effects prominent in zero-range processes exhibiting a condensation transition are studied by using continuous-time Monte Carlo simulations. We observe that, well above the thermodynamic critical point, both ...
