Analogue Hawking Radiation as a Tunneling in a Two-Level PT-Symmetric System

In light of a general scenario ovation toddler helmet of a two-level non-Hermitian PT-symmetric Hamiltonian, we apply the tetrad-based method to analyze the possibility of analogue Hawking radiation.We carry this out by making use of the conventional null-geodesic approach, wherein the associated Hawking radiation is described as a quantum tunneling process across a classically raspberry hershey kisses forbidden barrier on which the event horizon imposes.An interesting aspect of our result is that our estimate for the tunneling probability is independent of the non-Hermitian parameter that defines the guiding Hamiltonian.
