Quantum mechanics using two auxiliary inner products
Original language description
The current applications of non-Hermitian but PT-symmetric Hamiltonians H cover several, mutually not too closely connected subdomains of quantum physics. Mathematically, the split between the open and closed systems can be characterized by the respective triviality and non-triviality of an auxiliary inner-product metric Theta = Theta(H). With our attention restricted to the latter, mathematically more interesting unitary-evolution case we show that the intuitive but technically decisive simplification of the theory achieved via an 'additional' PCT-symmetry constraint upon H can be given a deeper mathematical meaning via introduction of a certain second auxiliary inner product.
