Boiling Quantum Vacuum: Thermal Subsystems from Ground-State Entanglement [PDF]
In certain special circumstances, such as in the vicinity of a black hole or in a uniformly accelerating frame, vacuum fluctuations appear to give rise to a finite-temperature environment.

Adaptive Phase Estimation with Squeezed Vacuum Approaching the Quantum Limit [PDF]
Phase estimation plays a central role in communications, sensing, and information processing. Quantum correlated states, such as squeezed states, enable phase estimation beyond the shot-noise limit, and in principle approach the ultimate quantum limit in

Calibrated in-vacuum quantum efficiency system for metallic and III-V thin-film photocathodes [PDF]
The construction and calibration of a high vacuum system for thin film growth and in situ quantum efficiency (QE) measurement are described. Surface cleaning by in situ argon ion sputtering and annealing is supported.

Probing the Purcell effect without radiative decay: lessons in the frequency and time domains
The effect of cavities or plates upon the electromagnetic quantum vacuum are considered in the context of electro-optic sampling (EOS), revealing how they can be directly studied. These modifications are at the heart of e.g.

Effects of the Quantum Vacuum at a Cosmic Scale and of Dark Energy. [PDF]
The Einstein equation in a semiclassical approximation is applied to a spherical region of the universe, with the stress-energy tensor consisting of the mass density and pressure of the ΛCDM cosmological model plus an additional contribution due ...

RELATIVITY OF MOTION IN QUANTUM VACUUM [PDF]
The problem of relativity of motion in quantum vacuum is addressed by considering a cavity moving in vacuum in a monodimensional space. The cavity is an open system which emits photons when it oscillates in vacuum. Qualitatively new effects like pulse shaping in the time domain and frequency conversion in the spectrum may help to discrimate motion ...
