Optical analogues of black-hole horizons
Yuval Rosenberg
Hawking radiation is unlikely to be measured from a real black-hole, but can be tested in laboratory analogues. It was predicted as a consequence of quantum mechanics and general r…

Cherenkov Radiation of Light Bullets
Ulf Leonhardt, Yuval Rosenberg
Electrically charged particles, moving faster than the speed of light in a medium, emit Cherenkov radiation. Theory predicts electric and magnetic dipoles to radiate as well, with…

Observation of Stimulated Hawking Radiation in Optics
Jonathan Drori, Yuval Rosenberg, David Bermudez +2
The theory of Hawking radiation can be tested in laboratory analogues of black holes. We use light pulses in nonlinear fiber optics to establish artificial event horizons. Each pul…
