报告内容介绍：
We study the long-time behavior of a driven tagged particle ina non-nearest-neighbor exclusion process in dimension one. Iwill present two scenarios when the tagged particle has aspeed. In the asymmetric exclusion process, the tagged particlecan have a positive speed even when its total drift is negative. In the symmetric exclusion process with a removal rule, thetagged particle satisfies a law of large numbers and a largedeviation principle. In particular, the speed and the largedeviations rate function can be computed explicitly. We willcharacterize some nontrivial invariant measures for theenvironment process viewed from the tagged particle. Ourarguments are based on couplings and color schemes.
