Nonequilibrium fluctuations for a tagged particle in mean-zero one-dimensional zero-range processes
M. D. Jara, C. Landim, S. Sethuraman
We prove a non-equilibrium functional central limit theorem for the position of a tagged particle in mean-zero one-dimensional zero-range process. The asymptotic behavior of the ta…

Diffusive variance for a tagged particle in asymmetric simple exclusion
Sunder Sethuraman
We study the equilibrium fluctuations of a tagged particle in finite-range simple exclusion processes on Z^d with biased single particle jump rates. It is known the variance of the…

Growth of preferential attachment random graphs via continuous-time branching processes
K. B. Athreya, A. P. Ghosh, S. Sethuraman
A version of ``preferential attachment'' random graphs, corresponding to linear ``weights'' with random ``edge additions,'' which generalizes some previously considered models, is…
