Dielectric microcavityLamb shiftWhispering gallery modeEffective potential wellWe study the normal modes and quasi-normal modes (QNMs) in circular dielectric microcavities through non-Hermitian Hamiltonian, which come from the modifications due to system鈥揺nvironment coupling. Differences between the two...

In both cases, the non-Hermitian model is valid when the energy range determined by the eigenvalues of the ring Hamiltonian is smaller than the energy band in the lead. Under such condition, we show that results about the interplay of opening and disorder, previously obtained within the non-...

It is shown that for a given Hermitian Hamiltonian possessing supersymmetry, there is always a non-Hermitian Jaynes-Cummings-type Hamiltonian (JCTH) admitting entirely real spectra. The parent supersymmetric Hamiltonian and the corresponding non-Hermitian JCTH are simultaneously diagonalizable. The exact ...

Hamiltonians having this property need not be Hermitian, but, except when PCT is spontaneously broken, the energy levels of such Hamiltonians are all real and positive! In this talk I examine quantum mechanical and quantum field theoretic systems whose Hamiltonians are non-Hermitian but obey PCT...
根据(10)我们可以通过 η(t)=U(t)[M(t)−I]1/2 (13)求得η(t)。注意, U(t) 是任意酉变换,可以自由选择。 所以,原则上我们只要根据求得 M(t) 和η(t) ,然后在指定一个 Hs,a(++)(t) Hs,a(++)(t) 即可根据(8)式求出完整的 Hs,a(t) 。而 Hs,a(++)(t) 可以是任意的厄米算符。
