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 $\QTR{it}{H}$…

Resonances from Higher Order S-Matrix Poles with Exponential Decay
C. Puntmann, P. Patuleanu
In analogy to Gamow vectors describing resonance states from first order S-matrix poles, one can define Gamow vectors from higher order poles of the S-matrix. With these vectors we…
