Phys. Rev. Lett. 95, 240601 (2005) [4 pages]Bethe Ansatz Solution of the Asymmetric Exclusion Process with Open BoundariesReceived 31 August 2005; published 8 December 2005 We derive the Bethe ansatz equations describing the complete spectrum of the transition matrix of the partially asymmetric exclusion process with the most general open boundary conditions. For totally asymmetric diffusion we calculate the spectral gap, which characterizes the approach to stationarity at large times. We observe boundary induced crossovers in and between massive, diffusive, and Kardar-Parisi-Zhang scaling regimes. © 2005 The American Physical Society URL:
