摘要 (Abstract)：
Investigations otnon-hermitianquantumsystemsrecently has drawn much interest in the field of holographyand the AdS/CFT correspondence. In this talk, I will focus onnon-hermiticity of the PT symmetrie type and, after a shortintroduction into the subject, present new results for a PTsymmetric system of interest in holography: I will discuss ourrecent [l]investigation of the phase structure and theinteraction induced quantum critical conductivity in a Psymmetric non-hermitian holographie metal. In partcular, theconductivity shows interesting new features in the differenphases,which are qualitativelyreproducedinaPsymmetrically deformed version ofLandau-Ginzburg theory.will end up with adiscussion of possible futureinvestigations in this model.
