Analogue Hawking radiation as a tunneling in a two-level -symmetric system
arXiv:2304.14174 · doi:10.3390/e25081202
Abstract
In the light of a general scenario of a two-level non-Hermitian -symmetric Hamiltonian we apply the tetrad-based method to analyze the possibility of analogue Hawking radiation. It is done 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 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.
