Analogue Hawking Radiation in a dc-SQUID Array Transmission Line
arXiv:0904.2589 · doi:10.1103/PhysRevLett.103.087004
Abstract
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.
