Analogue Hawking Radiation in a dc-SQUID Array Transmission Line

Understand

We propose the use of a superconducting waveguide formed from an array of dc-SQUID's for investigating analogue Hawking radiation.

• Biasing the array with a space-time varying flux modifies the propagation velocity of the waveguide, leading to an effective metric with an horizon.
• Being a fundamentally quantum mechanical device, this setup allows for investigations of quantum effects such as back-reaction and analogue space-time fluctuations on the Hawking process.
