We show that a detector acquires a Berry phase due to its motion in spacetime. The phase is different in the inertial and accelerated case as a direct consequence of the Unruh effect. We exploit this fact to design a novel method to measure the Unruh effect. Surprisingly, the effect is detectable for accelerations 10(9) times smaller than previous proposals sustained only for times of nanoseconds.

Decoherence as a detector of the Unruh effect
We propose a new type of the Unruh-DeWitt detector which measures the decoherence of the reduced density matrix of the detector interacting with the massless quantum scalar field. We find that the
Geometric phase for an accelerated two-level atom and the Unruh effect
We study, in the framework of open quantum systems, the geometric phase acquired by a uniformly accelerated two-level atom undergoing nonunitary evolution due to its coupling to a bath of fluctuating
Universality and thermalization in the Unruh effect
We explore the effects of different boundary conditions and coupling schemes on the response of a particle detector undergoing uniform acceleration in optical cavities. We analyze the thermalization
Vacuum Condensate, Geometric Phase, Unruh Effect, and Temperature Measurement
In our previous work the possibility to use the Aharonov-Anandan invariant as a tool in the analysis of disparate systems has been shown, including Hawking and Unruh effects, as well as graphene
Detecting the Change of Hawking Temperature with Geometric Phase
We show the possibility to detect Hawking radiation by geometric phase with Dirac particles. If the initial state of the particle is near the ground state, the geometric phase experiences a sudden
Unruh Effect without Thermality.
It is shown that uniformly accelerated detectors can display genuinely thermal features even if the Kubo-Martin-Schwinger (KMS) condition fails to hold, and the necessary and sufficient conditions for the response function of an accelerated detector to be thermal in the infinitely adiabatic limit are extracted.
Unruh effect and information flow
We study memory effects as information backflow for an accelerating two-level detector weakly interacting with a scalar field in the Minkowski vacuum. This is the framework of the well-known Unruh
Velocity effects on an accelerated Unruh–DeWitt detector
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
Unruh effect for detectors in superposition of accelerations
The Unruh effect is the phenomenon that accelerated observers detect particles even when inertial observers experience the vacuum state. In particular, uniformly accelerated observers are predicted


Decay of accelerated protons and the existence of the Fulling-Davies-Unruh effect.
The weak decay of uniformly accelerated protons in the context of standard quantum field theory is investigated by considering the Fulling-Davies-Unruh effect to achieve equality in inertial and coaccelerated frames.
Backreaction and the Unruh effect: New insights from exact solutions of uniformly accelerated detectors
Using nonperturbative results obtained recently for a uniformly accelerated Unruh-DeWitt detector, we discover new features in the dynamical evolution of the detector's internal degree of freedom,
Testing Unruh Radiation with Ultraintense Lasers
We point out that using the state-of-the-art (or soon-to-be) intense electromagnetic pulses, violent accelerations that may be suitable for testing quantum field theory in curved spacetime can be
Analogue Hawking radiation in a dc-SQUID array transmission line.
A superconducting transmission line formed from an array of direct-currentsuperconducting quantum interference devices for investigating analogue Hawking radiation by biasing the array with a space-time varying flux leads to an effective metric with a horizon.
The adiabatic theorem and Berry’s phase
A study is presented of Berry’s observation that when a quantum‐mechanical system is transported on a closed adiabatic journey, a topological phase arises in addition to the usual dynamical phase
The Unruh effect and its applications
It has been 30 years since the discovery of the Unruh effect. It has played a crucial role in our understanding that the particle content of a field theory is observer dependent. This effect is
Geometric phases for mixed states in interferometry.
This work defines the parallel transport condition that provides a connection form for obtaining the geometric phase for mixed states and reduces to well known formulas in the pure state case when a system undergoes noncyclic and unitary quantum evolution.
Fiber-Optical Analog of the Event Horizon
This work used ultrashort pulses in microstructured optical fibers to demonstrate the formation of an artificial event horizon in optics and observed a classical optical effect: the blue-shifting of light at a white-hole horizon.
Enhancing acceleration radiation from ground-state atoms via cavity quantum electrodynamics.
When ground-state atoms are accelerated through a high Q microwave cavity, radiation is produced with an intensity which can exceed the intensity of Unruh acceleration radiation in free space by many
