    "abstract": "On one-dimensional two-way infinite quantum lattice system, a property of\ntranslationally invariant stationary states with nonvanishing current\nexpectation is investigated. We consider GNS representation with respect to\nsuch a state, on which we have a group of space-time translation unitary\noperators. We show that spectrum of the unitary operators, energy-momentum\nspectrum with respect to the state, has a singularity at the origin.",
