Summary:
Researchers propose quantum circuit black hole lasers to explore Hawking radiation.
The fundamental forces of physics govern the matter comprising the Universe, yet exactly how these forces work together is still not fully understood. The existence of Hawking radiation -- the particle emission from near black holes -- indicates that general relativity and quantum mechanics must cooperate. But directly observing Hawking radiation from a black hole is nearly impossible due to the background noise of the Universe, so how can researchers study it to better understand how the forces interact and how they integrate into a "Theory of Everything"?
According to Haruna Katayama, a doctoral student in Hiroshima University's Graduate School of Advanced Science and Engineering, since researchers cannot go to the Hawking radiation, Hawking radiation must be brought to the researchers. She has proposed a quantum circuit that acts as a black hole laser, providing a lab-bench black hole equivalent with advantages over previously proposed versions. The proposal was published on Sept. 27 Scientific Reports.
"In this study, we devised a quantum-circuit laser theory using an analogue black hole and a white hole as a resonator," Katayama said.
A white hole is a theoretical partner of a black hole that emits light and matter in equal opposition to light and matter a black hole consumes. In the proposed electric circuit, a metamaterial engineered to allow faster-than-light motion spans the space between horizons, near which Hawking radiation is emitted.
