Pseudo-Hermitian Description of PT-Symmetric Systems Defined on a Complex Contour
Ali Mostafazadeh
We describe a method that allows for a practical application of the theory of pseudo-Hermitian operators to PT-symmetric systems defined on a complex contour. We apply this method…
Comment on Complex Extension of Quantum Mechanics
Ali Mostafazadeh
In their Erratum [Phys. Rev. Lett. {\bf 92}, 119902 (2004), quant-ph/0208076], written in reaction to [quant-ph/0310164], Bender, Brody and Jones propose a revised definition for a…
Conserved Current Densities, Localization Probabilities, and a New Global Gauge Symmetry of Klein-Gordon Fields
A. Mostafazadeh, F. Zamani
For free Klein-Gordon fields, we construct a one-parameter family of conserved current densities , with , and use the latter to yield a manifestly covariant expr…
A Critique of PT-Symmetric Quantum Mechanics
Ali Mostafazadeh
We study the physical content of the PT-symmetric complex extension of quantum mechanics as proposed in Bender et al, Phys. Rev. Lett. 80, 5243 (1998) and 89, 270401 (2002), and sh…
Eigenvalue Problem for Schroedinger Operators and Time-Dependent Harmonic Oscillator
Ali Mostafazadeh
It is shown that the eigenvalue problem for the Hamiltonians of the standard form, , is equivalent to the classical dynamical equation for certain harmonic oscilla…
On a Class of Quantum Canonical Transformations and the Time-Dependent Harmonic Oscillator
Ali Mostafazadeh
Quantum canonical transformations corresponding to the action of the unitary operator is studied. It is shown that for , the effect of th…
