Physics Letters B, 2015 In this article, we investigate the nonlocal behavior of the quantum state of fermionic system having the alpha vacuum. We evaluate the maximum violation of CHSH inequality in the quantum state.

Probing the symmetry breaking of a light–matter system by an ancillary qubit
Nature Communications, 2023 Hybrid quantum systems in the ultrastrong, and even more in the deep-strong, coupling regimes can exhibit exotic physical phenomena and promise new applications in quantum technologies.

The localized quantum vacuum field [PDF]
Physica Scripta, 2008 A model for the localized quantum vacuum is proposed in which the zero-point energy of the quantum electromagnetic field originates in energy- and momentum-conserving transitions of material systems from their ground state to an unstable state with negative energy. These transitions are accompanied by emissions and re-absorptions of real photons, which

Quantum Vacuum Photon Modes and Superhydrophobicity [PDF]
Physical Review Letters, 2015 Nanostructures are commonly used for developing superhydrophobic surfaces. However, available wetting theoretical models ignore the effect of vacuum photon-modes alteration on van der Waals forces and thus on hydrophobicity. Using first-principle calculations, we show that superhydrophibicity of nanostructured surfaces is dramatically enhanced by ...

Modelling the polarisation mode control of single quantum-dot emission in elliptical micro-pillar microcavities based on DBR mirror pairs using the FDTD method [PDF]
, 2006 We use the finite difference time domain method (FDTD) to investigate polarisation control of single-photon emission from single quantum dots confined in elliptical micro-pillar microcavities.

About thermodynamics of Schwarzschild black holes in a three-dimensional quantum vacuum with generalized uncertainty relations [PDF]
Kragujevac Journal of ScienceBy considering a modified version of generalized uncertainty relations in the model of a three-dimensional dynamic quantum vacuum characterized by a variable energy density, new relevant perspectives of analysis of the thermodynamics of Schwarzschild ...

Cherenkov Radiation from the Quantum Vacuum [PDF]
Physical Review Letters, 2019 A charged particle moving through a medium emits Cherenkov radiation when its velocity exceeds the phase velocity of light in that medium. Under the influence of a strong electromagnetic field, quantum fluctuations can become polarized, imbuing the vacuum with an effective anisotropic refractive index and allowing the possibility of Cherenkov radiation

The Unruh Vacuum and the “In-Vacuum” in Reissner-Nordström Spacetime
Universe, 2023 The Unruh vacuum is widely used as a quantum state to describe black hole evaporation since, near the horizon, it reproduces the physical state of a quantum field, the so-called “in-vacuum”, in the case where a black hole is formed by gravitational ...
