Abstract: Analog Hawking radiation emitted by a perfectly reflecting mirror in (1+3)-dimensional flat spacetime is investigated. This is accomplished by studying the reflected frequency and momentum based on Einstein mirror, instead of the canonical way of solving, if possible, wave equations subjected to a dynamical Dirichlet boundary condition. In the case of a finite-size mirror, diffraction pattern appears in the radiation spectrum. Based on the relevant parameters in the proposed AnaBHEL experiment, where the Hawking temperature TH = 0.03 eV and the mirror area A = 0.1 mm2, the Hawking photon yield is estimated to be N = 16 per laser shot (assuming a high reflectivity mirror can be generated in the proposed AnaBHEL experiment).

Non-Hermitian Waveguide Cavity QED with Tunable Atomic Mirrors [4.98050766876065]
We study an open cavity made of atom-dimer mirrors with a tunable reflection spectrum. We find that the atomic cavity shows anti-$mathcalPT$ symmetry. Our work presents a non-Hermitian theory of an anti-$mathcalPT$ atomic cavity.

Motion induced excitation and electromagnetic radiation from an atom facing a thin mirror [62.997667081978825]
We evaluate the probability of (de-)excitation and photon emission from a neutral, moving, non-relativistic atom, coupled to a quantum electromagnetic field and in the presence of a thin, perfectly conducting plane ("mirror") Results extend to a more realistic model, where the would-be electron was described by a scalar variable, coupled to an (also scalar) vacuum field.

Interferometry of black holes with Hawking radiation [0.0]
We investigate the wave optical imaging of black holes with Hawking radiation. For a short wavelength, the image of the black hole with the outgoing mode of the Unruh-Hawking state has the appearance of a star with its surface given by the photon sphere. For a long wavelength, the entire field of view is bright, and the emission region of Hawking radiation cannot be identified.

Collective spontaneous emission of two entangled atoms near an oscillating mirror [50.591267188664666]
We consider the cooperative spontaneous emission of a system of two identical atoms, interacting with the electromagnetic field in the vacuum state. Using time-dependent theory, we investigate the spectrum of the radiation emitted by the two-atom system. We show that it is modulated in time, and that the presence of the oscillating mirror can enhance or inhibit the decay rate.

High-Frequency Gravitational-Wave Detection Using a Chiral Resonant Mechanical Element and a Short Unstable Optical Cavity [59.66860395002946]
We suggest the measurement of the twist of a chiral mechanical element induced by a gravitational wave. The induced twist rotates a flat optical mirror on top of this chiral element, leading to the deflection of an incident laser beam. We estimate a gravitational wave strain sensitivity between 10-21/sqrtHz and 10-23/sqrtHz at around 10 kHz frequency.
