C, PT, and CPT invariance of pseudo-Hermitian Hamiltonians
Zafar Ahmed
Abstract
We propose construction of a unique and definite metric (η+), time-reversal operator (T) and an inner product such that the pseudo-Hermitian matrix Hamiltonians are C, PT, and CPT invariant and PT(CPT)-norm is indefinite (definite). Here, P and C denote the generalized symmetries : parity and charge-conjugation respectively. The limitations of the other current approaches have been brought out.
