Abstract: | Extended quantum mechanics using non-Hermitian (pseudo-Hermitian) Hamiltonians H = H
is briefly reviewed. A few related mathematical experiments concerning supersymmetric regularizations, solvable simulations and large-N expansion techniques are summarized. We suggest that they could initiate a deeper study of nonlocalized structures (quasi-particles) and/or of their unstable and many-particle generalizations. Using the Klein-Gordon example for illustration, we show how the PT symmetry of its Feshbach-Villars Hamiltonian H
FV might clarify experimental aspects of relativistic quantum mechanics. |
