Keywords:superconducting quantum circuits, analogue black holes, solitons

In the previous meeting, we proposed an analogue black hole in a transmission line with superconducting nonlinear asymmetric inductive elements (SNAILs). In the transmission line, a soliton solution is analytically derived by the reductive perturbation method and the soliton modulates the velocity of electromagnetic waves propagating in the transmission line, resulting in generating an analogue black hole. In this presentation, we show that the soliton is also obtained numerically. This system could be a promising candidate to observe Hawking radiation because it is experimentally reported to generate microwave entangled photons.
