Abstract: We study the influence of acceleration on the twin-Fock state which is a class of specific multibody entangled quantum state and was already realized experimentally with high precision and sensitivity. We show that the multi-body quantum entanglement can be increased with the acceleration, consistent with the "anti-Unruh effect" in reference to the counterintuitive cooling previously pointed out for an accelerated detector coupled to the vacuum. In particular, this kind of entanglement increase can lead to the improvement of the phase sensitivity, which provides a way to test the anti-Unruh effect in the future experiments.

Influence of field mass and acceleration on entanglement generation [0.0]
We find that the maximum entanglement between detectors does not exhibit a strict monotonic dependence on detector acceleration. Novelly, our findings indicate the absence of a strong anti-Unruh effect in (3+1)-dimensional massive scalar fields.

Observation-dependent suppression and enhancement of two-photon coincidences by tailored losses [68.8204255655161]
Hong-Ou-Mandel (HOM) effect can lead to a perfect suppression of two-particle coincidences between the output ports of a balanced beam splitter. In this work, we demonstrate experimentally that the two-particle coincidence statistics of two bosons can instead be seamlessly tuned to substantial enhancement. Our findings reveal a new approach to harnessing non-Hermitian settings for the manipulation of multi-particle quantum states.

Detectable Signature of Quantum Friction on a Sliding Particle in Vacuum [58.720142291102135]
We show traces of quantum friction in the degradation of the quantum coherence of a particle. We propose to use the accumulated geometric phase acquired by a particle as a quantum friction sensor. The experimentally viable scheme presented can spark renewed optimism for the detection of non-contact friction.

Unruh Effect of Detectors with Quantized Center-of-Mass [0.0]
The Unruh effect is the prediction that particle detectors accelerated through the vacuum get excited by the apparent presence of radiation quanta. Here, we study more realistic detectors whose center of mass is a quantized degree of freedom being accelerated by an external classical field. We find that the recoil due to the emission of Unruh quanta may be a relevant experimental signature of the Unruh effect.

The Unruh effect in slow motion [0.0]
We show in what regimes the probe forgets' that it is traversing cavities and thermalizes to a temperature proportional to its acceleration. We analyze in detail how this thermalization relates to the renowned Unruh effect. We propose an experimental testbed for the direct detection of the Unruh effect at relatively low probe speeds and accelerations.

Enhanced decoherence for a neutral particle sliding on a metallic surface in vacuum [68.8204255655161]
We show that non-contact friction enhances the decoherence of the moving atom. We suggest that measuring decoherence times through velocity dependence of coherences could indirectly demonstrate the existence of quantum friction.

Beyond the Limits of Conventional Stark Deceleration [54.992903498251174]
Stark deceleration enables the production of cold and dense molecular beams with applications in trapping, collisional studies, and precision measurement. One of the chief limitations arises from the transverse focusing properties of Stark decelerators. We introduce a new operation strategy that circumvents this limit without any hardware modifications, and experimentally verify our results for hydroxyl radicals.
