    "abstract": "I present a microscopic description of Hawking radiation in sonic black\nholes. A one-dimensional Fermi-degenerate liquid squeezed by a smooth barrier\nforms a transonic flow, a sonic analogue of a black hole. The quantum treatment\nof the non-interacting case establishes a close relationship between the\nHawking radiation and quantum tunnelling through the barrier. Quasi-particle\nexcitations appear at the barrier and are then radiated with a thermal\ndistribution in exact agreement with Hawking\u0027s formula. The signature of the\nradiation can be found in the dynamic structure factor, which can be measured\nin a scattering experiment. The possibility for experimental verification of\nthis new transport phenomenon for ultra-cold atoms is discussed.",
