Nonequilibrium fluctuations for a tagged particle in one-dimensional sublinear rate zero-range processes
Milton Jara, Claudio Landim, Sunder Sethuraman
Nonequilibrium fluctuations of a tagged, or distinguished particle in a class of one dimensional mean-zero zero-range systems with sublinear, increasing rates are derived. In Jara-…

Metastability of reversible finite state Markov processes
Johel Beltran, Claudio Landim
We prove the metastable behavior of reversible Markov processes on finite state spaces under minimal conditions on the jump rates. To illustrate the result we deduce the metastable…
