Several models of quantum open systems are known at present to violate,
according to principles of the standard quantum theory of open systems, the
second law of thermodynamics. Here, a new and rather trivial model of another
type is suggested describing mechanism that violates, according to the same
principles, the zeroth and the second laws of thermodynamics simultaneously. Up
to a technically minor modification, the model resembles some models already
known, solved by standard means, and properly understood. Universal validity of
two basic principles of thermodynamics in strictly quantum situations is thus
simultaneously called in question.Comment: Extended reference list and acknowledgement
