Quantum vacuum radiation in optical glass
Quantum vacuum radiation in optical glass
A recent experimental claim of the detection of analogue Hawking radiation in an optical system [Phys. Rev. Lett. 105, 203901 (2010)] has led to some controversy [Phys. Rev. Lett. 107, 149401 (2011)]. While this experiment strongly suggests some form of particle creation from the quantum vacuum (and hence it is …
