Solvable PT symmetric Hamiltonians
Within the so called PT symmetric version of quantum mechanics a brief review of the exactly solvable models is given. Distinction is made between the curved and straight coordinate lines, between their unbounded (aperiodic) and bounded (periodic) choices, and between the completely and partially solvable cases.
متن کاملη-Pseudo-Hermiticity generators: radially symmetric Hamiltonians
Hamiltonian models with radial symmetry are considered and a class of their η-pseudo-Hermiticity generators is described. Illustrative examples are given, amongest are η-pseudo-Hermiticity generators for an η-pseudoHermitian Morse and an η-pseudo-Hermitian weakly perturbed harmonic oscillator models. PACS numbers: 03.65.Ge, 03.65.Fd,03.65.Ca
متن کاملFinite fringe analysis of two dimensional and axially-symmetric flows
We present an improved technique for automated interactive interferometric image data analysis and demonstrate its application to a wide range of flow configurations and conditions. The examples that we present to illustrate the technique range from the comparatively low velocity flow associated with the flight of an archery arrow to the hypersonic flow in a free-piston shock tunnel.
متن کاملNonlinear modes in finite-dimensional PT-symmetric systems.
By rearrangements of waveguide arrays with gain and losses one can simulate transformations among parity-time (PT-) symmetric systems not affecting their pure real linear spectra. Subject to such transformations, however, the nonlinear properties of the systems undergo significant changes. On an example of an array of four waveguides described by the discrete nonlinear Schrödinger equation with...
متن کاملInfinite dimensional non-positively curved symmetric spaces of finite rank
This paper concerns a study of three families of non-compact type symmetric spaces of infinite dimension. Although they have infinite dimension they have finite rank. More precisely, we show they have finite telescopic dimension. We also show the existence of Furstenberg maps for some group actions on these spaces. Such maps appear as a first step toward superrigidity results.
