More precisely, the eigenvalues of a deformation of the Markov matrix of the process, connected to the cumulant generating function of the current, are computed in two different ways. The first excited states are recovered from the ground state eigenvalue (obtained by matrix product ansatz) by analytic continuation. They are then compared with the asymptotics of the Bethe ansatz equations. The eigenstates are put in correspondence with the sheets of a Riemann surfaces, which is the maximal domain of definition of the analytic continuation of the ground states. Connections are made with KPZ universality and previous results on the TASEP with periodic boundary conditions.<\/p>\n<p>&nbsp;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Ulysse Godreau (LPT) Abstract : The totally asymmetric exclusion process (TASEP) is a continuous time Markov process much studied in statistical physics featuring particles with hard-core interaction hopping randomly on&hellip;&nbsp;<a href=\"https:\/\/fermi.univ-tlse3.fr\/fr\/home\/event\/riemann-surfaces-for-the-totally-asymmetric-simple-exclusion-process-with-open-boundaries-ulysse-godreau-lpt-seminar-05-04-14-h\/\" rel=\"bookmark\">Lire la suite &raquo;<span class=\"screen-reader-text\">Riemann surfaces for the totally asymmetric simple exclusion process with open boundaries (Ulysse Godreau\/ LPT \/ Seminar). &#8211;
