Macroscopic car condensation in a parking garage.

摘要: An asymmetric exclusion process type process, where cars move forward along a closed road that starts and terminates at parking garage, displays dynamic phase transitions into two types of condensate phases the garage becomes macroscopically occupied. The total car density ${\ensuremath{\rho}}_{o}$ exit probability \ensuremath{\alpha} from are control parameters. At transition, number parked ${N}_{p}$ diverges in both cases, with length ${N}_{s},$ as ${N}_{p}\ensuremath{\sim}{N}_{s}^{{y}_{p}}$ ${y}_{p}=1/2.$ Towards vanishes ${N}_{p}\ensuremath{\sim}{\ensuremath{\epsilon}}^{\ensuremath{\beta}}$ $\ensuremath{\beta}=1,$ $\ensuremath{\epsilon}=|\ensuremath{\alpha}\ensuremath{-}{\ensuremath{\alpha}}^{*}|$ or $\ensuremath{\epsilon}=|{\ensuremath{\rho}}_{o}^{*}\ensuremath{-}{\ensuremath{\rho}}_{o}|$ being distance transition. transition normal represents also onset transmission information through garage. This gives rise to unusual autocorrelations profiles near which depend strongly on group velocity fluctuations road.
