• Abstract: Atoms falling into a black hole (BH) through a cavity are shown to enable coherent amplification of light quanta powered by the BH gravitational vacuum energy. This process can harness the BH energy towards useful purposes, such as propelling a spaceship trapped by the BH. The process can occur via transient amplification of a signal field by falling atoms that are partly excited by Hawking radiation reflected by an orbiting mirror. In the steady-state regime of thermally equilibrated atoms that weakly couple to the field, this amplifier constitutes a BH-powered quantum heat engine. The envisaged effects substantiate the thermodynamic approach to BH acceleration radiation.

• Schr\"odinger and Klein-Gordon theories of black holes from the quantization of the Oppenheimer and Snyder gravitational collapse [0.0]
  The Schr"odinger equation of the Schwarzschild black hole (BH) shows that a BH is composed of a particle, the "electron", interacting with a central field, the "nucleus" The analogy between this BH Schr"odinger equation and the Schr"odinger equation of the s states of the hydrogen atom permits us to solve the same equation. BHs are well defined quantum gravitational systems obeying Schr"odinger's theory: the "gravitational hydrogen atoms"

• The BHL-BCL crossover: from nonlinear to linear quantum amplification [55.2480439325792]
  The black-hole laser (BHL) effect is the self-amplification of Hawking radiation between a pair of horizons which act as a resonant cavity. In a flowing atomic condensate, the BHL effect arises in a finite supersonic region, where Bogoliubov-Cherenkov-Landau (BCL) radiation is resonantly excited by any static perturbation. Here, we perform a theoretical study of the BHL-BCL crossover using an idealized model where both phenomena can be unambiguously isolated.

• Nonthermal radiation of evaporating black holes [0.0]
  Black hole (BH) evaporation is caused by creation of entangled particle-antiparticle pairs near the event horizon. We show that due to entanglement between photons moving inside and outside the event horizon, nonunitary absorption of the negative energy photons near the BH center, alters the outgoing radiation. As a result, radiation of the evaporating BH is not thermal; it carries information about BH interior, and entropy is preserved during evaporation.

  Cavity quantum electrodynamics (QED) uses a cavity to engineer the mode structure of the vacuum electromagnetic field. Controllably decoupling a qubit from the cavity's photon population, effectively cloaking the qubit from the cavity. Experiment demonstrates how qubit cloaking can be exploited to cancel ac-Stark shift and measurement-induced dephasing.

• Probing the symmetry breaking of a light--matter system by an ancillary qubit [50.591267188664666]
  Hybrid quantum systems in the ultrastrong, and even more in the deep-strong, coupling regimes can exhibit exotic physical phenomena. We experimentally observe the parity symmetry breaking of an ancillary Xmon artificial atom induced by the field of a lumped-element superconducting resonator. This result opens a way to experimentally explore the novel quantum-vacuum effects emerging in the deep-strong coupling regime.

The quantum walks of quasi-particle in the curved spacetime reflect the gravitational effect near the black hole, resulting in the behaviour of stimulated Hawking radiation.

• Gravitational waves affect vacuum entanglement [68.8204255655161]
  The entanglement harvesting protocol is an operational way to probe vacuum entanglement. Using this protocol, it is demonstrated that while the transition probability of an individual atom is unaffected by the presence of a gravitational wave, the entanglement harvested by two atoms depends sensitively on the frequency of the gravitational wave. This suggests that the entanglement signature left by a gravitational wave may be useful in characterizing its properties, and potentially useful in exploring the gravitational-wave memory effect and gravitational-wave induced decoherence.
