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…
