Hermitian system是什么

Witryna27 sty 2024 · We study the time evolution of two-states non-Hermitian systems. The exact time-dependent wavefunctions are obtained with the evolution operates. It is shown that the non-Hermitian systems behave like the corresponding Hermitian systems, i.e., periodically oscillating between the two states, when the eigenenergy is real. But … Witryna10 kwi 2024 · the Hermitian and the non-Hermitian dynamics comes from the phase of , which is = 2 for the Hermitian case and = 2 for the non-Hermitian case.
