A team of theoretical physicists has proposed a way to simulate black holes on an electronic chip. Additionally, the technology used to create these lab-made black holes may be useful for quantum technologies. The researchers from the University of Chile, Cedenna, TU Eindhoven, Utrecht University, and FOM will publish their results in Physical Review Letters on 1 February 2017.
Black holes are astronomical objects so dense that nothing – not even light – can escape their gravitational pull once it passes a point of no return called the event horizon. The researchers have discovered how to make such points of no return for spin waves, fluctuations that propagate in magnetic materials, by using the behaviour of these waves when they interact with electric currents.
