Rigged Hilbert Space Resonances and Time Asymmetric Quantum Mechanics
A. Bohm, H. Kaldass
The Rigged Hilbert Space (RHS) theory of resonance scattering and decay is reviewed and contrasted with the standard Hilbert space (HS) theory of quantum mechanics. The main differ…

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 $\QTR{it}{H}$…
