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-…
