Time-Reversal and Irreversibility
A. Bohm, P. Kielanowski
abstract: The time reversal and irreversibility in conventional quantum mechanics are
compared with those of the rigged Hilbert space quantum mechanics. We discuss
the time evolution of Gamow and Gamow-Jordan vectors and show that the rigged
Hilbert space case admits a new kind of irreversibility which does not appear
in the conventional case. The origin of this irreversibility can be traced back
to different initial-boundary conditions for the states and observables. It is
shown that this irreversibility does not contradict the experimentally tested
consequences of the time-reversal invariance of the conventional case but
instead we have to introduce a new time reversal operator.
