Hawking radiation in optics and beyond

Raul Aguero-Santacruz, David Bermudez

Hawking radiation was originally proposed in astrophysics, but it has been generalized and extended to other physical systems receiving the name of analogue Hawking radiation. In t…

Instabilities in an optical black-hole laser

Juan David Rincon-Estrada, David Bermudez

The Hamiltonian of optical fields in a nonlinear dispersive fiber is studied. Quantum field fluctuations are spontaneously created close to an optical event horizon through the ana…

Hawking temperature in dispersive media: Analytical and numerical study

Alhan Moreno-Ruiz, David Bermudez

In the context of analog gravity the Hawking effect can be generalized to domains outside astrophysics. Arguably, the most successful systems for this analogy have been so far the…

Resonant Hawking radiation as an instability

David Bermudez, Ulf Leonhardt

We consider a simple model for a black-hole laser: a Bose-Einstein condensate with uniform speed of sound and partially uniform flow, establishing two horizons, a black-hole and a…

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…

Eigenvalue Determination for Mixed Quantum States using Overlap Statistics

Lázaro Alonso, David Bermudez, Thomas Gorin

We consider the statistics of overlaps between a mixed state and its image under random unitary transformations. Choosing the transformations from the unitary group with its invari…
