Query: Quantum induced w = -1 crossing of the quintessence and phantom models   Considering the single scalar field models of dark energy, i.e. the
quintessence and phantom models, it is shown that the quantum effects can cause
the system crosses the w = -1 line. This phenomenon does not occur in classical
level. The quantum effects are described via the account of conformal anomaly.
