For stochastic processes leading to condensation, the condensate, once it is formed, performs an ergodic stationary-state motion over the system. We analyse this motion, and especially its characteristic time, for zero-range processes. The characteristic time is found to grow with the system size much faster than the diffusive time scale, but not exponentially fast. This holds both in the mean-field geometry and on finite-dimensional lattices. In the generic situation where the critical mass…

Motion of condensates in non-Markovian zero-range dynamics
The condensation transition in a non-Markovian zero-range process is studied in one and higher dimensions. In the mean-field approximation, corresponding to infinite-range hopping, the model exhibits
Coarsening dynamics of zero-range processes
We consider a class of zero-range processes exhibiting a condensation transition in the stationary state, with a critical single-site distribution decaying faster than a power law. We present the
Zero-range processes with multiple condensates: statics and dynamics
The steady-state distributions and dynamical behaviour of zero-range processes with hopping rates which are non-monotonic functions of the site occupation are studied. We consider two classes of
Finite-size effects in dynamics of zero-range processes.
TLDR
The finite-size effects prominent in zero-range processes exhibiting a condensation transition are studied by using continuous-time Monte Carlo simulations and it is shown that several dynamical characteristics undergo a qualitative change at this density.
Condensation in stochastic mass transport models: beyond the zero-range process
We consider an extension of the zero-range process to the case where the hop rate depends on the state of both departure and arrival sites. We recover the misanthrope and the target process as
Dynamics of Condensation in the Totally Asymmetric Inclusion Process
We study the dynamics of condensation of the inclusion process on a one-dimensional periodic lattice in the thermodynamic limit, generalising recent results on finite lattices for symmetric dynamics.
Metastability in a condensing zero-range process in the thermodynamic limit
Zero-range processes with decreasing jump rates are known to exhibit condensation, where a finite fraction of all particles concentrates on a single lattice site when the total density exceeds a
Discontinuous Condensation Transition and Nonequivalence of Ensembles in a Zero-Range Process
We study a zero-range process where the jump rates do not only depend on the local particle configuration, but also on the size of the system. Rigorous results on the equivalence of ensembles are

We study a zero-range process where the jump rates do not only depend on the local particle configuration, but also on the size of the system. Rigorous results on the equivalence of ensembles are
Condensation in the Inclusion Process and Related Models
TLDR
For inclusion processes with homogeneous stationary measures, condensation is established in the limit of vanishing diffusion strength in the dynamics, and several details about how the limit is approached for finite and infinite systems are given.

TLDR
The criterion for the occurrence of a condensation transition is derived, the precise nature of the shape and the size of the condensate in the condensed phase are analyzed and the results are interpreted within the framework of sums of random variables.
