  • Cryptohermitian Picture of Scattering Using Quasilocal Metric Operators 
    Znojil, M. (Symmetry, Integrability and Geometry: Methods and Applications, 2009)
    One-dimensional unitary scattering controlled by non-Hermitian (typically, PT-symmetric) quantum Hamiltonians H ≠ H† is considered. Treating these operators via Runge-Kutta approximation, our three-Hilbert-space formulation ...
  • On the Role of the Normalization Factors κn and of the Pseudo-Metric P ≠ P† in Crypto-Hermitian Quantum Models 
    Znojil, M. (Symmetry, Integrability and Geometry: Methods and Applications, 2008)
    Among P-pseudo-Hermitian Hamiltonians H = P⁻¹H†P with real spectra, the ''weakly pseudo-Hermitian'' ones (i.e., those employing non-self-adjoint P ≠ P†) form a remarkable subfamily. We list some reasons why it deserves a ...
  • Planarizable Supersymmetric Quantum Toboggans 
    Znojil, M. (Symmetry, Integrability and Geometry: Methods and Applications, 2011)
    In supersymmetric quantum mechanics the emergence of a singularity may lead to the breakdown of isospectrality between partner potentials. One of the regularization recipes is based on a topologically nontrivial, multisheeted ...
  • Three-Hilbert-Space Formulation of Quantum Mechanics 
    Znojil, M. (Symmetry, Integrability and Geometry: Methods and Applications, 2009)
    In paper [Znojil M., Phys. Rev. D 78 (2008), 085003, 5 pages, arXiv:0809.2874] the two-Hilbert-space (2HS, a.k.a. cryptohermitian) formulation of Quantum Mechanics has been revisited. In the present continuation of this ...
