Is the hamiltonian hermitian
Witryna18 mar 2024 · We saw that the eigenfunctions of the Hamiltonian operator are orthogonal, and we also saw that the position and momentum of the particle could not be determined exactly. We now examine the generality of these insights by stating and proving some fundamental theorems. WitrynaIn Section 3.1, when discussing the case of a Hermitian Hamiltonian, we identified these with trajectories which connect the classical turning points through the …

Witrynaeral pseudo-Hermitian Hamiltonians, develop pseudo-supersymmetric quantum mechanics, and study some concrete examples, namely the Hamiltonian of the two-component Wheeler-DeWitt equation for the FRW-models coupled to a real massive scalar field and a class of pseudo-Hermitian Hamiltonians with a real spectrum. 1 … Witrynae ective non-Hermitian Hamiltonian to obtain the evo-lution of any input state in a fully quantum domain. The above are the main contributions of this work, because any non-classical state that is constrained to Markovian dynamics, can be equivalently described in terms of light state crossing non-Hermitian systems (e.g., waveguides or
