Query: Time-dependent evolution of two coupled Luttinger liquids   We consider two disconnected Luttinger liquids which are coupled at $t=0$
through chiral density-density interactions. Both for $t<0$ and $t \geq 0$ the
system is exactly solvable by means of bosonization and this allows 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 in real experiments.
