Analogue Hawking radiation as a tunneling in a two-level $\mathcal{P}\mathcal{T}$-symmetric system

Bijan Bagchi, Rahul Ghosh, Sauvik Sen

In the light of a general scenario of a two-level non-Hermitian $\mathcal{P}\mathcal{T}$-symmetric Hamiltonian we apply the tetrad-based method to analyze the possibility of analogue Hawking…
