In recent works we have used quantum tools in the analysis of the time evolution ofseveral macroscopic systems. The main ingredient in our approach is the self-adjointHamiltonian H of the system S. This Hamiltonian quite often, and in particular forsystems with a finite number of degrees of freedom, gives rise to reversible andoscillatory dynamics. Sometimes this is not what physical reasons suggest. We discusshere how to use non self-adjoint Hamiltonians to overcome this difficulty: the timeevolution we obtain out of them show a preferable arrow of time, and it is not reversible.Several applications are constructed, in particular in connection to information dynamics.
