In light of 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 t... https://www.sharemaza.com/product-category/brooch/
