Hilbert Space or Gelfand Triplet - Time Symmetric or Time Asymmetric Quantum Mechanics

A. Bohm, H. Kaldass, P. Patuleanu

Intrinsic microphysical irreversibility is the time asymmetry observed in exponentially decaying states. It is described by the semigroup generated by the Hamiltonian $\QTR{it}{H}$…
