Parity symmetric

Web1 Jun 2024 · As many concepts that originated from non-Hermitian physics, the PT symmetry was first developed in the context of quantum mechanics but turned out to be a powerful tool in several other branches of physics, including electronic (), acoustic (10, 11), and particularly optics and photonics (12–15).In optical systems, the parity operator … WebThe literature mentioned above was mainly concerned with parity (P) - time (T) symmetric systems, whose linear Hamiltonians commute with the PT -operator. In this work we address the possibility of anti- PT symmetry of the linear Hamiltonian, as concerns the existence and stability of the associated nonlinear modes.
