Enhancement of Unruh effect in high-intensity laser fields using hyperbolic metamaterials (2008.04846v1)
Published 9 Aug 2020 in physics.optics and gr-qc
Abstract: High-intensity laser fields acting on free electrons were proposed to create sufficiently large accelerations to enable detection of Unruh radiation. However, the currently achievable electron accelerations are not large enough. Here we demonstrate that Unruh effect in high-intensity laser fields is strongly enhanced near hyperbolic metamaterials, so that many orders of magnitude smaller accelerations may be used to detect Unruh radiation.
