title: Non-Hermitian PT-Symmetric Theories creator: Beygi, Alireza subject: ddc-500 subject: 500 Natural sciences and mathematics subject: ddc-530 subject: 530 Physics description: This dissertation concerns the concept of PT symmetry as a replacement of the conventional symmetry of the Dirac Hermiticity of the operators, in particular, for the Hamiltonian. After solving a controversial issue surrounding the claimed violation of the special relativity by PT-symmetric quantum mechanics, we move further to discuss PT symmetry for the systems whose associated time reversal symmetry is odd, i.e., T^2 = −1. Our results, as published papers, are incorporated in the subsequent chapters. Then we conclude by suggestions for future work. date: 2019 type: Dissertation type: info:eu-repo/semantics/doctoralThesis type: NonPeerReviewed format: application/pdf identifier: https://archiv.ub.uni-heidelberg.de/volltextserverhttps://archiv.ub.uni-heidelberg.de/volltextserver/26903/1/Dissertation.pdf identifier: DOI:10.11588/heidok.00026903 identifier: urn:nbn:de:bsz:16-heidok-269039 identifier: Beygi, Alireza (2019) Non-Hermitian PT-Symmetric Theories.
