【 摘 要 】

We consider two disconnected Luttinger liquids which are coupled at t=0 through chiral density-density interactions. Both for t < 0 and t >= 0 the system is exactly solvable by means of bosonization and this allows us to evaluate analytically the time dependence of correlation functions. We find that in the long-time limit the critical exponent governing the one-particle correlation function differs from the exponent dictated by the equilibrium ground state of the coupled system. We also discuss how this reflects on some physical quantities which are accessible to real experiments.
