• Authors: S. Bhuvaneswari, R. Muthuganesan and R. Radha
• Abstract summary: We investigate the quantum correlations and coherence of two accelerating Unruh-deWitt detectors coupled to a scalar field in 3 + 1 Minkowski space-time. We show that the entanglement is completely destroyed in the limit of infinite acceleration while the local quantum uncertainty and l1-norm of coherence remain nonzero.

• Abstract: In this paper, we investigate the quantum correlations and coherence of two accelerating Unruh-deWitt detectors coupled to a scalar field in 3 + 1 Minkowski space-time. We show that the entanglement is completely destroyed in the limit of infinite acceleration while the local quantum uncertainty and l1-norm of coherence remain nonzero. In addition, we also highlight the role of Unruh temperature and energy spacing of detectors on quantum correlations for different choices of initial states.

  This work focuses on the theoretical feasibility of probing quantum properties in de Sitter (dS) and Anti-de Sitter (AdS) spacetimes via detectors. By employing the Unruh-DeWitt detector coupled with a massless scalar field, quantum uncertainty and quantum coherence in both dS and AdS spacetimes are investigated.

• Accelerated detector in a superposed spacetime [0.0]
  We find resonance peaks in the detector response at rational ratios of the superposed compactified lengths, which we observe to be accentuated by the acceleration of the detector. For the first time we confirm the detailed balance condition due to acceleration in a superposition of spacetimes, commensurate with the Unruh effect in a single spacetime state.

  We investigate the completion of a nonadiabatic evolution into a shortcut to adiabaticity for a quantum field confined within a one-dimensional cavity containing two movable mirrors. We achieve a smooth extension of the Moore functions that implements the STA. We draw attention to the existence of a comparable problem within nonrelativistic quantum mechanics.

  We consider an Unruh-DeWitt detector coupled to a quantum scalar field in the (2+1)-dimensional Minkowski spacetime. We find that both the accelerated detector's dissipation rate and the shift of its frequency caused by the coupling to the field bath depend on the acceleration temperature.

Our scheme can directly extract the decoherence of the phase-sensitive quantum correlation $langle hatahatbrangle$ between two entangled modes. This is an experimental study on the decoherence effect of a squeezed vacuum state, which has been rarely investigated.
