We analyze the response of an Unruh-DeWitt detector moving along an unbounded spatial trajectory in a two-dimensional spatial plane with constant independent magnitudes of both the four-acceleration and of a timelike proper time derivative of the four-accelration. In a Fermi-Walker frame moving with the detector, the direction of the acceleration rotates at a constant rate around a great circle. This is the motion of a charge in a uniform electric field when in the frame of the charge there is… 

Static detectors and circular-geodesic detectors on the Schwarzschild black hole

We examine the response of an Unruh-DeWitt particle detector coupled to a massless scalar field on the (3+1)-dimensional Schwarzschild spacetime, in the Boulware, Hartle-Hawking and Unruh states, for

Does relativistic motion always degrade quantum Fisher information?

We investigate the ultimate estimation precision, characterized by the quantum Fisher information, of a two-level atom as a detector which is coupled to massless scalar field in the Minkowski vacuum.

Relation between quantum effects in general relativity and embedding theory

We discuss results relevant to the relation between quantum effects in a Riemannian space and on the surface appearing as a result of its isometric embedding in a flat space of a higher dimension. We

Measuring acceleration using the Purcell effect

We show that a two-level atom resonantly coupled to one of the modes of a cavity field can be used as a sensitive tool to measure the proper acceleration of a combined atom-cavity system. To achieve

When Hawking into Unruh mapping works

We discuss for which smooth embeddings of a metric into a flat ambient space the Hawking into Unruh mapping takes place? We show that for some new embeddings of the Schwarzschild and

Embeddings of the black holes in a flat space

Two new minimal embeddings of the Schwarzchild-de Sitter metric which smoothly cover both horizons of this metric are obtained.

When does the Hawking into Unruh mapping for global embeddings work?

A bstractWe discuss for which smooth global embeddings of a metric into a Minkowskian spacetime the Hawking into Unruh mapping takes place. There is a series of examples of global embeddings into the

Unruh-DeWitt detector event rate for trajectories with time-dependent acceleration

We analyze the response function of an Unruh-DeWitt detector moving with time-dependent acceleration along a one-dimensional trajectory in Minkowski spacetime. To extract the physics of the process,

Fulling-Unruh effect in general stationary accelerated frames

We study the generalized Unruh effect for accelerated reference frames that include rotation in addition to acceleration. We focus particularly on the case where the motion is planar, with the

Unruh-DeWitt particle detector models are studied in a variety of time-dependent and time-independent settings. We work within the framework of first-order perturbation theory and couple the detector

Modified dispersion relations and the response of the rotating Unruh-DeWitt detector

We study the response of a rotating monopole detector that is coupled to a massless scalar field which is described by a nonlinear dispersion relation in flat spacetime. Since it does not seem to be

We analyse within first-order perturbation theory the instantaneous transition rate of an accelerated Unruh–DeWitt particle detector whose coupling to a massless scalar field on four-dimensional

Quantum electrodynamics of accelerated atoms in free space and in cavities

We consider a gedanken experiment with a beam of atoms in their ground state that are accelerated through a single-mode cavity. We show that taking into account of the “counterrotating” terms in the

Considerations on the Unruh effect: causality and regularization

This paper is motivated by the observation that calculations of the Unruh effect based on idealized particle detectors are usually made in a way that involves integrations along the entire detector

Then again, how often does the Unruh–DeWitt detector click if we switch it carefully?

The transition probability in the first-order perturbation theory for an Unruh–DeWitt detector coupled to a massless scalar field in Minkowski space is calculated. It has been shown recently that the

The stationary world lines, on which quantized field detectors in a vacuum have time-independent excitation spectra, are discussed. They are characterized by the requirement that the geodetic
