The Phenomenological Preparation - Registration Arrow of Time and its Semigroup Representation in the RHS Quantum Theory
Arno R. Bohm, Raymond Scurek
The observed probabilities of quantum mechanics possess a time asymmetry which is based on the truism that a state must be prepared before an observable can be measured in it. Whil…
Relativistic Resonances, Relativistic Gamow Vectors and Representations of the Poincare' Semigroup
Arno R. Bohm, N. L. Harshman, M. J. Mithaiwala
The foundations of time asymmetric quantum theory are reviewed and are applied to the construction of relativistic Gamow vectors. Relativistic Gamow vectors are obtained from the r…
Relativistic Gamow Vectors II
A. Bohm, H. Kaldass, S. Wickramasekara +1
Motivated by the debate of possible definitions of mass and width of resonances for -boson and hadrons, we suggest a definition of unstable particles by ``minimally complex'' se…
Resonances, Gamow Vectors and Time Asymmetric Quantum Theory
Arno R. Bohm, Raymond Scurek, Sujeewa Wikramasekara
Decaying states can be represented by Gamow vectors with an exponential, asymmetric time evolution. This asymmetric evolution is a manifestation of irreversibility on the microphys…
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 $\QTR{it}{H}$…
The Rigged Hilbert Space Formulation of Quantum Mechanics and its Implications for Irreversibility
C. Schulte, R. Twarock, A. Bohm
Quantum mechanics in the Rigged Hilbert Space formulation describes quasistationary phenomena mathematically rigorously in terms of Gamow vectors. We show that these vectors exhibi…
