Author(s): Sumit Kumar Jana, Ryo Hanai, Tan Van Vu, Hisao Hayakawa, and Archak Purkayastha While considering non-Hermitian Hamiltonians arising in the presence of dissipation, in most cases, the dissipation is taken to be frequency-independent. However, this idealization may not always be applicable in experimental settings, where dissipation can be frequency-dependent. Such frequency-dep… [Phys. Rev.
