Integrable models from PT-symmetric deformations
Paulo E. G. Assis, Andreas Fring
We address the question of whether integrable models allow for PT-symmetric deformations which preserve their intgrability. For this purpose we carry out the Painleve test for PT-s…
PT-symmetric extensions of the supersymmetric Korteweg-de Vries equation
Bijan Bagchi, Andreas Fring
We discuss several PT-symmetric deformations of superderivatives. Based on these various possibilities, we propose new families of complex PT-symmetric deformations of the supersym…
Non-Hermitian Hamiltonians of Lie algebraic type
Paulo E. G. Assis, Andreas Fring
We analyse a class of non-Hermitian Hamiltonians, which can be expressed bilinearly in terms of generators of a sl(2,R)-Lie algebra or their isomorphic su(1,1)-counterparts. The Ha…
PT-symmetric deformations of Calogero models
Andreas Fring, Miloslav Znojil
We demonstrate that Coxeter groups allow for complex PT-symmetric deformations across the boundaries of all Weyl chambers. We compute the explicit deformations for the A_2 and G_2-…
