- Title: The Unruh effect in slow motion
- Authors: Silas Vriend, Daniel Grimmer and Eduardo Mart\'in-Mart\'inez
- Abstract summary: 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.

- Abstract: We show under what conditions an accelerated detector (e.g., an
atom/ion/molecule) thermalizes while interacting with the vacuum state of a
quantum field in a setup where the detector's acceleration alternates sign
across multiple optical cavities. We show (non-perturbatively) in what regimes
the probe `forgets' that it is traversing cavities and thermalizes to a
temperature proportional to its acceleration. Then we analyze in detail how
this thermalization relates to the renowned Unruh effect. Finally, we use these
results to propose an experimental testbed for the direct detection of the
Unruh effect at relatively low probe speeds and accelerations, potentially
orders of magnitude below previous proposals.

We show that a purely-noninertial radiative shift as large as 50 times the inertial energy shift can be obtained at small, experimentally achievable accelerations.
We argue that the radiative energy-level shift is a promising observable for detecting Unruh thermality with current technology.

The density of field modes inside such a cavity shows a it resonance structure i.e. it rises abruptly for some specific cavity configurations.
We show that an accelerating detector inside the cavity exhibits a non-trivial excitation and de-excitation rates for it small accelerations around such resonance points.

We show that the Zitterbewegung effect manifests itself as a series of quantum beats of the particle density in the long-time limit.
We also find a time-domain where the particle density of the point source is governed by the propagation of a main wavefront.
The relative positions of these wavefronts are used to investigate the time-delay of quantum waves in the Klein-tunneling regime.
