Symmetry parity

Weba class of non-Hermitian Hamiltonians having parity–time (PT) symmetry. They calculated the eigenvalues of truncated matrices for the non-Hermitian Hamiltonian operators in the basis set of the eigenfunctions of the harmonic oscillator and argued that their results did not agree with those of Bender and Boettcher [2]. They concluded that the ... WebParity is an important idea in quantum mechanics because the wavefunctions which represent particles can behave in different ways upon transformation of the coordinate system which describes them. Under the parity transformation: The parity transformation changes a right-handed coordinate system into a left-handed one or vice versa.
