Title: The inclusion process: dynamics and condensation.


Abstract:

The inclusion process is an interacting particle system where particles perform random walks on a finite (or countable) set and have an attractive interaction.

It is a natural bosonic counterpart of the extensively studied exclusion process, and is exactly solvable in the same sense.

I will provide an introduce to this process and show some of its basic properties, such as
self-duality, product stationary measures, and duality with an interacting diffusion process that describes a model of heat conduction.


If the random walk rate becomes small w.r.t. the attractive interaction and many particles are in the system, condensates -i.e. huge piles of particles- start to form. We analyse the limiting metastable dynamics of these condensates. On an appropriate time scale, this dynamics consist of a mixture of diffusive merging of condensates and random walk of individual condensates, until a single condensate is formed, which then continues to move as a random walk.
