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

In light of radio birdman tshirt a general scenario 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 forbidden barrier on which the event horizon imposes.An interesting aspect of our result is that our estimate for the tunneling dorisvale station for sale probability is independent of the non-Hermitian parameter that defines the guiding Hamiltonian.
