Non-real Eigenvalues for PT-Symmetric Double Wells
, 2015 We study small, PT-symmetric perturbations of self-adjoint double-well Schr\"odinger operators in dimension $n\geq 1$. We prove that the eigenvalues stay real for a very small perturbation, then bifurcate to the complex plane as the perturbation gets ...

European Journal of Inorganic Chemistry, Volume 28, Issue 6, February 21, 2025.Diiiridium complexes bridged by μ2‐oxamidato ligands give highly efficient phosphorescent organic light emitting diodes with greenish‐yellow emission. Abstract Three neutral diiridium(III) complexes with 2‐fluorenylpyridyl (flpy) or 5‐fluoro‐2‐fluorenylpyridyl (flpyF) as C^N cyclometalating ligands and a μ2‐oxamidato bridge have been synthesized.
